From the eyes of a chemist Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Polypharmacy: the complex landscape of multiple medications 10/07/25, 10:30 Last updated: Published: 21/09/24, 15:48 From the eyes of a chemist The concurrent use of many medications by a patient, known as polypharmacy, poses a complex challenge to modern healthcare, especially for the elderly and those with chronic diseases. Polypharmacy raises the risk of adverse drug responses, drug interactions, and medication non-adherence, even though it is essential for managing complicated health concerns. To maximise patient outcomes and guarantee safe treatment regimens, it is crucial to recognise the chemical interactions and effects of different medications. The chemistry behind polypharmacy Polypharmacy stems from the intricate interactions between several chemicals in the human body. Every drug has unique chemical components intended to interact with biological targets in order to provide therapeutic benefits. Nevertheless, when several medications are taken at once, their combinations may have unexpected effects. Understanding polypharmacy requires a thorough understanding of pharmacokinetics—the way the body absorbs, distributes, metabolises, and excretes medications—and pharmacodynamics—the effects of pharmaceuticals on the body. For example, some pharmaceuticals may cause or inhibit the enzymes that metabolise other drugs, changing the levels of the drug and possibly increasing its toxicity or decreasing its effectiveness. Analytical methods in polypharmacy management Chemistry offers a number of analytical and instrumental techniques for efficient polypharmacy management. Drug levels in the blood are tracked using methods like mass spectrometry (MS) and high-performance liquid chromatography (HPLC) to make sure they stay within therapeutic ranges. These techniques support dose modifications by identifying possible medication interactions. Furthermore, it is impossible to exaggerate the importance of chemistry in the creation of drug interaction databases and predictive modelling instruments. By helping medical professionals foresee and minimise harmful medication interactions, these materials help to ensure patient safety. The role of healthcare professionals To successfully manage the complexity of polypharmacy, healthcare professionals—including physicians, chemists, and nurses—need to have a solid understanding of chemistry. Their expertise is essential for assessing each drug's requirement, taking possible interactions into account, and coming up with methods to make drug regimens easier to follow. Managing polypharmacy is especially important for chemists. They assess patients' prescriptions, look for any interactions, and suggest changes or substitutes using their knowledge of medicinal chemistry. Pharmacists who participate in collaborative care can greatly lower the hazards related to polypharmacy. Innovations in medication management Chemistry-driven advances in medical technology are improving polypharmacy management. Real-time alerts regarding potential drug interactions can be provided to prescribers through computerised physician order entry (CPOE) systems that are coupled with clinical decision support systems (CDSS). Optimising polypharmacy may also be possible with the emergence of personalised medicine, which adjusts drug regimens according to a patient's genetic profile. Conclusion Polypharmacy remains a significant challenge in healthcare, demanding a comprehensive understanding of chemistry and pharmacology to manage effectively. Healthcare practitioners can minimise the hazards associated with several medications and provide safer and enhanced patient care by utilising modern analytical methods, prediction technologies, and multidisciplinary teamwork.

Delving into the impacts of gut bacteria on health Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The Gut Microbiome 11/07/25, 09:58 Last updated: Published: 04/04/24, 16:41 Delving into the impacts of gut bacteria on health Inflammatory Bowel Disease The microbiome is hugely important to human health, and has been shown to beneficial to digestion, the immune system and even our mental health when in good working condition. However, disruption to the balance of the microbial flora has likewise been associated with multiple diseases and poor general health. Dysbiosis, or a poor balance, of human microbiome communities has been implicated in a wide range of disease, such as cardiovascular disease, chronic inflammation, obesity and even mental health issues. A diverse and well-balanced microbial community is important for disease prevention, however modern over usage of antibiotics as well as poor diets low in dietary fibre and high in artificial additives can lead to compromised communities dominated by single pathogenic strains of bacteria. The human microbiome plays a critical role in overall health, from providing valuable metabolites to aiding the immune system. Friendly commensal bacteria colonise major regions in our gut, with characteristic diverse communities of microbes inhabiting them. These microbes occupy these niches and outcompete pathogenic organisms, actively preventing infection and disease. In this article we will be specifically looking into the link between the gut microbiome and Inflammatory Bowel disease (IBD), as this is currently one of the most well researched cases of a causal relationship between the microbiome and disease state. Dysbiosis and Disease state Disruption of the gut flora is associated with painful inflammation of the gastrointestinal tract, diagnosed as IBD. Crohn’s disease and Ulcerative Colitis are conditions under the umbrella term of IBD and cause painful swelling and eventually ulcers in the gastrointestinal tract. The exact cause of IBD remains unclear, with the true cause likely a combination of genetics, environmental factors and the gut microbiome. Evidence has come to light that shows a link between disease state and the gut dysbiosis, where they influence each other and are potentially both each other’s cause and effect. Successfully treating IBD has proved difficult; medications focus on alleviating inflammation or other symptoms as antibiotics have shown limited effectiveness in curing the disease. Antibiotics have even been suggested to weaken the immune system long-term, as evidence suggests that antibiotic clearance of commensal bacteria can provide opportunity for pathogenic strains to establish themselves. Medical treatments destabilizing the microbiome can lead to a change in overall metabolism and chronic Clostridium difficile infection. When colonization resistance is compromised there is more opportunity for single bacteria to dominate the community, with antibiotic-associated diarrhoea a common side effect associated with antibiotic induced dysbiosis. Microbial-based therapies Recently potential therapies pivoted to target the microbiota, as reinstating a healthy colony of gut microbials should alleviate the cause of IBD. Previous treatments relied on antibiotics followed by a course of probiotics; however, this has had variable levels of success as the antibiotic treatment can further reduce bacterial diversity in the gut. Probiotics have limited effectiveness in alleviating symptoms; any effect is transient as no probiotic microbial strains are detectable after 2 weeks of stopping intake. In modern clinical trials we have already seen positive results from microbiome treatments in clearing C. difficile infection, such as faecal microbiota transplantation (FMT) therapy. FMT uses faeces from a healthy donor, which are processed and delivered to the gastrointestinal tract of patients. Faeces contain a high microbial load, with up to 1011 bacterium per gram and multiple archaea, fungi and viruses that could not be delivered orally in a probiotic form. Success in resolving dysbiosis through FMT is variable but shows more promise than other therapies. Future Potential Specific forms of IBD such as ulcerative colitis (UC) was first treated with FMT in 1989, with patients reducing medications within a week of enema treatments and remaining clinically disease free for multiple years after treatment. More recent trials have had more variable levels of remission, suggesting donor compatibility, disease prevalence and engraftment of the microbiota all factor into the success of FMT. There is potential in this therapy, as FMT has proved more robust than previous treatments for IBD. Modern research into the relationship between disease and gut flora has come a long way in a relatively short time and shows there is much potential for future research in this area.

The different models of health and disease Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Beyond medicine: understanding health through various stances 16/10/25, 10:21 Last updated: Published: 22/04/24, 10:24 The different models of health and disease Introduction Various models can show what factors produce health outcomes between individuals and populations. This article looks at the biomedical, social, humanistic and biopsychosocial models, reviewing each through examples and its applications to the real world. With this said, every model has advantages and disadvantages because they are imperfect. Each one is essential as it provides a way to treat patients, so they need to be used alongside one another to address the different aspects involved in a person’s health. Biomedical model- figure 1 To start with the most familiar, the biomedical model looks at finding the cause of illness through a physiological perspective, i.e. finding malfunctions in organs and cells. For example, infections are caused by microorganisms, or metabolic disorders usually occur due to at least one critical genetic mutation. This model has some advantages, such as using evidence-based strategies to treat patients, and it has contributed to medical breakthroughs that have improved overall health. Also, it can lead to effective treatment plans through medical interventions to handle specific diseases. However, the biomedical model does not consider external factors involved in illness. Moreover, it focuses on curing diseases instead of preventative plans that may be more successful, and its recommendation of pharmaceutical drugs for certain conditions may cause addiction, which is another health problem. Social-ecological model- figure 2 Now, the social-ecological model considers societal factors, ranging from economic to political, that are influential in population health. It helps investigate non-communicable and infectious diseases. An advantage of this model is it emphasises preventative strategies, which can lead to long-term advancements in health. Moreover, it encourages cooperation within communities in shaping initiatives that benefit everyone and regards collaboration between multiple work sectors like education and law enforcement as vital to progressing society. A significant downside of the social model is that it is complicated, suggesting it is difficult to tackle all of these determinants of health effectively. In turn, allocating resources to resolve specific issues would take much work. Lastly, some detractors of this model believe it absolves people’s responsibility for their health. Humanistic model- figure 3 Subsequently, the humanistic model is about an individual’s wellbeing, experiences, and self-exploration. Its applications are mainly in psychology, though it can manifest in other areas of life through a person making decisions they are satisfied with. A few advantages of this model include prioritising a person’s autonomy, encouraging their psychological well-being, and facilitating collaboration between clinicians and patients in treatment. On the other hand, only some can think for themselves or their experiences; the model relies on subjectivity, so it can be challenging to measure parts of well-being, and it is more beneficial for chronic conditions than acute ailments. Biopyschosocial model- figure 4 The biopsychosocial (BPS) model includes biological, psychological and social factors related to a patient’s health. Therefore, it can be used for any individual with chronic or acute disease(s) and is used broadly in psychology between the psychiatrist/ counsellor and the patient. One advantage is that it aids primary care doctors in comprehending the interrelations between an illness's biological and psychosocial parts. In turn, this strengthens the patient-clinician relationship. Similar to the social model, this can promote preventative measures against diseases. However, the addition of biological and psychosocial factors makes the model complicated to implement in clinical contexts. Moreover, there needs to be more distinct guidelines for its use in treating patients compared to the biomedical model. Lastly, applying the biopsychosocial can change between healthcare practices, possibly leading to different standards of care. Conclusion Reflecting on the models outlined, the biopsychosocial model seems to be the perfect one compared to the others because it includes all of the models above or others not mentioned in this article. In turn, it succeeds in providing a balanced view of health. On the other hand, as iterated before, the BPS model has its disadvantages. Thus, it may require more refinements to be widely implemented across healthcare settings.

The endowment effect Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Behavioural Economics II 31/10/25, 12:46 Last updated: Published: 22/03/24, 19:51 The endowment effect This is article no. 2 in a series on behavioural economics. Next article: Loss aversion . Previous article: The role of honesty . In microeconomics, we say preferences are reversible. If you would pay £2 for a bar of chocolate, then you would be happy to sell a bar of chocolate for £2, especially if I gave it to you for free. Sounds reasonable? Well, in fact, this is not the case. Once again, consumers, just like you and me, are irrational, and thanks to what’s known as the endowment effect, classical economics falls flat once again. The endowment effect In an experiment conducted by Knetsch, participants were randomly allocated into three different categories. The first were given a coffee mug, the second were given some candy, and the third were given nothing. We say that the first two groups were endowed; they were given an item for free at no cost to them. Then the participants in the first two groups were given the option to either swap their item for either the mug or the candy or keep the item they were endowed with. The third group, treated as a control, was given the option to choose between the two and keep which they preferred the most. In the control group, we saw that about half of the participants chose the mug and half chose the candy. But in the endowed groups, an overwhelming majority decided to keep the item they were given rather than swapping! Therefore, as we can clearly see, when someone is endowed with an item, their perception of its utility (or benefit) seems to increase, so when given the opportunity to switch items, they often decline. Clearly, from an economic perspective, when endowed with an item, your utility curve for that item differs from when given the opportunity to choose. But why might that be the case? When you are endowed with an item, you own that item and, in a sense, hold responsibility over it. You become possessive, and this sense of ownership seems to have its own psychological value; therefore, the act of giving it up for something of equal worth is no longer treated as a fair trade-off. Whereas when not endowed, you have no sentiment value attached to the items, and for the most part, people are indifferent between them! A good example of this could be an old, run-down car. Buyers of this car see it for what it is—something that is barely functional. But owners of the car who have driven it for 20 years see it as more than that. There is an emotional attachment to the car that makes it more valuable in their eyes. Is the endowment effect always true? List conducted a similar experiment. A survey was undertaken by both unexperienced and experienced 'traders', and then after the survey, they were given trading cards as a reward. They were then given the opportunity to trade their cards if they wanted to. Non-experienced traders were subject to the endowment effect, so they kept the cards they worked hard for, but experienced traders knew that some cards may be more valuable, even if only slightly, which meant that they were able to overcome this effect. Additionally, what was found was that when participants were aware and went into the experiment knowing that there would be a trade, they had the intention to trade, which also managed to remove the endowment effect. In essence, the endowment effect serves as a reminder of the complexities inherent in human psychology and decision-making. There are many limitations in traditional economic models, which emphasises the need for behavioural economics and the inclusion of multidisciplinary thinking.

Preserving trust and exposing betrayal Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Uncovering the Disturbing World of Healthcare Serial Killers 14/07/25, 15:06 Last updated: Published: 25/02/24, 15:08 Preserving trust and exposing betrayal Background We depend heavily on medical professionals during our most defenceless and vulnerable moments, trusting them with our well-being. However, what would happen if this trust was broken? What if the medical professionals were to pose harm rather than fulfil their intended function as protectors? Healthcare serial killers are one of the most disturbing subsets of serial killers - the name itself suggests that individuals within the healthcare industry exploit their position to murder patients. True crime and media often go hand in hand in the modern era. There are many web series, TV dramas, and movies that delve into real-life narratives. Accumulating over 68.31 million hours watched, Netflix's film "The Good Nurse" in 2022, depicts the story of Charles Cullen, a figure recognised as one of the most prolific serial killers in American history. The film quickly rose to prominence and became the best-performing English-language film production on the platform. This phenomenon in media underscores a broader pattern wherein the portrayal of serial killers becomes increasingly prevalent within popular culture. Motives Criminologists and true crime filmmakers engaged in extensive efforts to figure out what motivates serial killers to carry out such horrific crimes for decades. The motives behind killings are diverse, complex and sometimes unknown. Some perpetrators may attempt to justify their actions by claiming to ease the patient's suffering under the guise of “mercy killing”. Others can be driven by the desire to be praised, to exert power or control over the patient, or to gain financial benefits. For example, Dr. Harold Shipman, a British doctor killed over 200 patients, primarily driven by sadistic motives. His misdeeds were ultimately exposed when he attempted to forge the will of one of his victims. Key traits and methods Although it might be tempting to create a list of characteristics typical of healthcare serial killers, no universally applicable formula defines their personalities. However, according to research by Yardley, E., and Wilson, D. (2016), attention-seeking, strange behaviour when a patient dies, and frequent changes in hospital working locations are characteristics that healthcare serial killers frequently exhibit. Furthermore, the study conducted by Birmingham City University criminologists shows that the most popular technique employed by healthcare serial killers is poisoning, specifically through insulin overdose. Notably, insulin overdose was the principal method employed by 25% of healthcare serial killers. For instance, in the case of British nurse Lucy Letby, who was given a life sentence for killing seven infants and attempting to murder six others, the use of an insulin overdose was a notable method employed. Ethics Examining the ethical implications of healthcare serial killing is essential, as it involves the breach of trust and violation of core principles of the healthcare profession. The relationship between a medical professional and a patient is based solely on trust, which healthcare serial killers have exploited. What's worse is that medical professionals frequently target elderly, chronically ill, or vulnerable patients, highlighting significant ethical issues. Challenges Detecting healthcare serial killers is difficult, primarily because their victims are frequently elderly or suffering from chronic illnesses. Investigations typically stem from an unusually high number of deaths rather than patient or family complaints. Even if the police initiate an investigation, it may be too late to collect physical evidence, as bodies may have been cremated or significantly decomposed, leaving no trace of substances in the patients' systems. Furthermore, in rare cases where a medical professional faces charges, they may use defences such as assisted suicides or attribute deaths to unintentional medical errors, potentially resulting in reduced sentences or lesser degrees of homicide . Conclusion Healthcare serial killers are a deeply disturbing phenomenon within the medical profession. The idea that people upon whom we rely on to take care of us can occasionally exhibit malevolence is extremely unsettling. By employing research to understand the existence of serial killers in the healthcare industry, we can address the many questions that surround their behaviour. Studying the motive behind such crimes, looking at the key traits and methods, and addressing the challenges associated with identifying such perpetrators provide insights crucial for safeguarding the community of patients who are at risk and preserving the core moral principles of the medical field. Let’s conclude by saying that the way that healthcare serial killings are portrayed in popular media is a clear reminder of the moral and professional obligations inherent in the provision of healthcare.

The concept of memory erasure is huge and complex Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Can you erase your memory? 09/07/25, 13:31 Last updated: Published: 23/11/23, 11:08 The concept of memory erasure is huge and complex What is memory? Our brain is a wiggly structure in our skull, made up of roughly 100 billion neurones. It is a wondrous organ, capable of processing 34 gigabytes of digital data per day, yet being able to retain information, and form memory – something that many would argue, defines who we are. So.. what is memory? And how does our brain form them? Loosely defined, memory is the capacity to store and retrieve information. There are three types of memory: short-term, working, and long-term memory (LTM). Today, we will be focusing on LTM. In order to form LTM, we need to learn and store memory. This follows the process of encoding, storage, retrieval, and consolidation. In order to understand the biochemical attributes of memory in our brain, a psychologist, Dr Lashley, conducted extensive experiments on rats to investigate if there were specific pathways in our brain that we could damage to prevent memory from being recalled. His results showed that despite large areas of the brain being removed, the rats were still able to perform simple tasks ( Figures 1-2 ). Lashley’s experiment transformed our understanding of memory, leading to the concept of “engrams”. Takamiya et al., 2020 defines “memory engrams” as traces of LTM consolidated in the brain by experience. According to Lashley, the engrams were not localised in specific pathways. Rather, they were distributed across the whole of the brain. Can memory be erased? The concept of memory erasure is huge and complex. In order to simplify this, let’s divide them into two categories: unintentional, and intentional. Let’s take amnesia for example. This is a form of unintentional memory ‘erasure’. There are two types of amnesia: retrograde amnesia, and anterograde amnesia. Retrograde amnesia is the loss of memory that was formed before acquiring amnesia. On the other hand, anterograde amnesia is the inability to make new memories since acquiring amnesia. Typically, a person with amnesia would exhibit both retrograde, and anterograde amnesia, but at different degrees of severity ( Figure 3 ). Can we ‘erase’ our memory intentionally? And how would this be of use to us? This is where things get really interesting. Currently, the possibility of intentional memory ‘erasure’ is being investigated in patients for the treatment of post-traumatic stress disorder (PTSD). In these clinical trials, patients with PTSD are given drugs that block these traumatic memories. For example, propranolol, an adrenergic beta receptor blocker impairs the acquisition, retrieval, and reconsolidation of this memory. Incredible, isn’t it? Although this is not the current standard treatment for PTSD, we can only imagine how relieving it would be for our fellow friends who suffer from PTSD if their traumatic memories could be ‘erased’. However, with every step ahead, we must always be extremely cautious. What if things go wrong? We are dealing with our brain, arguably one of the most important organs in our body after all. Regardless, the potential for memory ‘erasure’ in treating PTSD seems both promising and intriguing, and the complexities and ethical considerations surrounding such advancements underscore the need for careful and responsible exploration in the realm of neuroscience and medicine.

Tackling stereotypes and equal access Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Why representation in STEM matters Last updated: 03/04/25, 10:38 Published: 13/03/25, 08:00 Tackling stereotypes and equal access In collaboration with Stemmettes for International Women's Month Representation in Science, Technology, Engineering, and Mathematics (STEM) and Science, Technology, Engineering, Art and Mathematics (STEAM), is crucial for everyone. Historically, STEM fields have been dominated by certain demographics that don’t show the true picture of our world. Maybe you grew up seeing no (or very few) women, people of colour, or other marginalised groups mentioned in your science curriculum. This needs to change because your voice, experiences and talents should be celebrated in any career you choose. Below, we’ll list some of the top reasons why representation is so important. Equal access Why does representation matter? Because it promotes equal access! Whether in an educational or career setting, seeing someone who looks like you do something you never thought possible can be life-changing. After all, you can’t be what you can’t see . Showing up in your role and sharing what you do or your STEM/STEAM interests show other people that these fields are accessible to everyone. Also, finding someone in a field you are (or would like to) get into is a great way to find a mentor, build a network, and boost your knowledge. Feeling excluded or discouraged is bound to happen at some point in your career, but anyone can succeed, no matter their background. Innovation When STEM fields are equally represented, better (and more innovative) ideas come to the table. Everything you’ve experienced can be useful in developing solutions to STEM and STEAM problems, no matter your level of education or upbringing. A lot of STEM doesn’t rely so much on your qualifications, but instead on your problem-solving, creativity, and innovation skills. For example, if you’re part of a culture that nobody else in your team has experienced, or you’ve experienced a disability and made adaptations for yourself, you bring a unique set of ideas to the table that can help solve many different problems. Inclusion There are many examples of when certain demographics haven’t been included in STEM decision-making processes. For example, many face recognition apps have failed to recognise the faces of people of colour, and period trackers have been made with misinformation about cycle lengths. If more diversity were seen throughout the process of creating a STEM product or service, we would see a lot fewer issues and a lot better products! Now, more than ever, your voice is important in STEM because science and technology are shaping the future at a fast rate. With the boom in artificial intelligence (AI) technology and its impact on almost every industry, we can’t afford to have models being trained from an unrepresentative data set. Look at people like Katherine Johnson, who despite facing setbacks as an African American at the time, was a pivotal part of sending astronauts aboard Apollo 11 into space. Or, more recently, Dr Ronx, who is paving the way as a trans-non-binary emergency medicine doctor. Tackling stereotypes Showing up in STEM & STEAM fields is a great way to tackle stereotypes. So many underrepresented groups are usually stereotyped into different career paths that are based on old, outdated notions about what certain people should do. By showing up and talking about what you love, you show that you’re not less capable than anyone else. Shout about your achievements, no matter how big or small, no matter where you are on your career journey so that we can encourage a new idea of what STEM looks like. Conclusion If this article hasn’t already given you the confidence to explore STEM and STEAM fields and all they have to offer, there are so many other reasons why you’re important to these fields and capable of achieving your dreams. Representation from you and others helps us create a more equitable, innovative, and inclusive future. It matters because the progress of science and society depends on the contributions of all, not a select few.

And can we overcome them? Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The Challenges in Modern Day Chemistry 11/07/25, 09:56 Last updated: Published: 24/02/24, 22:09 And can we overcome them? Chemistry, heralded as the linchpin of the natural sciences, serves as the veritable bedrock of our comprehension of the world and concurrently takes on a pivotal role in resolving the multifaceted global challenges that confront humanity. In the context of the modern era, chemistry has undergone a prodigious transformation, with research luminaries persistently challenging the fringes of knowledge and technological application. However, this remarkable trajectory is shadowed by a constellation of intricately interwoven challenges that mandate innovative and often paradigm-shifting solutions. This article embarks on a comprehensive exploration of the salient and formidable challenges that presently beset the discipline of contemporary chemistry. Sustainability and the Imperative of Green Chemistry The paramount challenge confronting modern chemistry pertains to the burgeoning and compelling imperative of environmental sustainability. The chemical industry stands as a colossal contributor to ecological degradation and the inexorable depletion of vital resources. Consequently, an exigent necessity looms: the development of greener and environmentally benign chemical processes. Green chemistry, an avant-garde discipline, is at the vanguard of this transformation, placing paramount emphasis on the architectural design of processes and products that eschew the deployment of hazardous substrates. Researchers within this sphere are diligently exploring alternative, non-toxic materials and propounding energy-efficient methodologies, thereby diminishing the ecological footprint intrinsic to chemical procedures. Energy Storage and Conversion at the Frontier In an epoch marked by the surging clamour for renewable energy sources such as photovoltaic solar panels and wind turbines, the exigency of efficacious energy storage and conversion technologies attains unparalleled urgency. Chemistry assumes a seminal role in the realm of advanced batteries, fuel cells, and supercapacitors.

You can have endometriosis and PCOS at the same time Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Are PCOS and endometriosis sisters? 09/07/25, 10:52 Last updated: Published: 30/01/24, 21:33 You can have endometriosis and PCOS at the same time The label of PCOS or endometriosis can have physical and emotional consequences for women. It is important for both male and females to gain a better understanding of such conditions, the symptoms and the challenges they pose. Such knowledge can act as physical and emotional support in times of need. It creates a safe space where the person with PCOS is comfortable discussing their experiences, feelings and concerns knowing they are being heard and supported by the right people. With research fast developing there is a plethora of information out there, so WHAT do you believe in and WHAT do you ignore and WHOM do you believe and WHOM do you ignore? Endometriosis and polycystic ovary syndrome (PCOS) both affect females and can have similar symptoms. However, the causes and some key symptoms are different. Endometriosis is a painful disorder in which tissue that normally lines the inside of your uterus grows outside the uterus. (Read more on Endometriosis breakthrough ). PCOS is an endocrine system disorder where small fluid-filled sacs develop in the ovaries. You can have endometriosis and PCOS at the same time. A 2015 study found that women with PCOS had a higher risk for a diagnosis of endometriosis. Another 2014 study determined that there is a strong link between endometriosis and PCOS with pelvic pain and trouble getting pregnant. What is a normal menstrual cycle? Let’s polish up the basics! The brain, ovaries and uterus work together to prepare the body per month for pregnancy. Follicle-stimulating Hormone (FSH) and Luteinising Hormone (LH) are made by the pituitary gland and progesterone and oestrogen are made in the ovaries. Many females with PCOS do not ovulate regularly and it may take these females longer to become pregnant. Irregular periods results in months where ovulation does not occur. Where the ovaries do not produce progesterone the lining of the uterus becomes thicker but shedding is very irregular which can lead to heavy and prolonged bleeding. PCOS affects 1 in 10 women in the UK. Women with PCOS experience irregular menstrual cycles, acne, excess hair growth, infertility, pregnancy complications and cardiovascular disease. PCOS can be associated with weight gain and obesity in approximately one-half of females. Females with PCOS can also be at increased risk of other problems that can impact quality of life. These include depression and anxiety, sexual dysfunction and eating disorders. Although PCOS is not ‘completely’ reversible there are many ways you can minimise the symptoms. Most females can lead a normal life and are able to conceive without significant complications. A pelvic examination is requested by your GP to assess the ovaries for a diagnosis to be made. Imaging tests for examining the ovaries are pelvic and intravaginal ultrasonography, however, the latter may be extremely uncomfortable if sexually inactive. Please be aware this article acts to capture your attention, encouraging you to delve further into the subject and continue your self-education on this topic and by no means is everything about PCOS. It is essential to consult with a healthcare professional if you suspect you may have symptoms of either PCOS or endometriosis. Proper diagnosis and management can help address specific concerns and improve overall reproductive health.
