Tag: PMOS treatment

If you’ve recently heard the term PMOS and wondered what it means, or if you’ve had a PCOS diagnosis for years and want to understand what’s changed, this is your complete guide. PMOS stands for polyendocrine metabolic ovarian syndrome. It’s the new name for what was previously called polycystic ovary syndrome (PCOS). The name has changed, but the condition hasn’t, and understanding it properly has never mattered more. PMOS affects an estimated 1 in 8 women and people with ovaries worldwide, more than 3.1 million in the UK alone. Despite being one of the most common hormonal conditions, it remains widely misdiagnosed, misunderstood, and undertreated. On average, it takes two years and multiple doctor visits to get a diagnosis. You deserve better than that. This guide covers everything: what PMOS actually is, what causes it, what it feels like, how it’s diagnosed, and what you can do about it. Quick facts: What is PMOS? P – PolyendocrineM – MetabolicO – OvarianS – Syndrome Let’s break that down: Polyendocrine means more than one hormone system may be involved. PMOS can affect reproductive hormones such as testosterone, LH and FSH, but it may also affect insulin, thyroid hormones, cortisol and other metabolic pathways. Metabolic refers to the way your body processes energy, sugar and insulin. Many people with PCOS/PMOS have some degree of insulin resistance, where the body has to produce more insulin to keep blood sugar stable. Ovarian reflects the fact that the ovaries may be affected, particularly ovulation. However, despite the old name “polycystic ovary syndrome”, you do not need to have cysts on your ovaries to have the condition. Syndrome means it is a collection of features that can look different from person to person. PMOS is the most common cause of irregular periods and ovulatory infertility in people with ovaries. It is also linked to an increased risk of developing insulin resistance and longer-term health risks including type 2 diabetes, cardiovascular disease, endometrial cancer, anxiety and depression. Is PMOS the same as PCOS? PMOS is just the newer name being used for PCOS. For years, the condition was called polycystic ovary syndrome (PCOS), but that name has always been a bit misleading. Not everyone with PCOS has polycystic-looking ovaries, and not everyone with polycystic-looking ovaries has PCOS. The condition also affects far more than the ovaries. The shift towards PMOS aims to better reflect the full-body nature of the condition, including its links with insulin resistance, androgen excess, metabolic health, cardiovascular risk, mental health and fertility. That said, PCOS is still the most widely recognised search term, and most NHS, NICE and clinical guidance currently still uses PCOS. So, for now, you may see both terms used: PCOS = the older, widely used namePMOS = the newer, more accurate name You can read more about why PCOS was renamed PMOS here. What causes PMOS? The exact cause of PMOS isn’t fully understood, but research points to a combination of genetic, hormonal and metabolic factors. It tends to run in families, and if your mother, sister or aunt has PMOS, you might be at a higher risk. At its core, PMOS involves a dysfunction in the way the body produces and responds to hormones, particularly androgens and insulin. Androgen excess – the ovaries (and in some cases the adrenal glands) produce higher levels of androgens than normal. Androgens are often called “male hormones,” but they play important roles in everyone’s body. In PMOS, elevated androgens disrupt the normal development of follicles in the ovaries, preventing regular ovulation. Insulin resistance – the majority of people with PMOS have some degree of insulin resistance, meaning their cells don’t respond efficiently to insulin. This causes the pancreas to produce more insulin to compensate, and elevated insulin in turn stimulates the ovaries to produce more androgens, creating a self-reinforcing cycle. Disrupted pituitary signalling – the hormonal signals from the brain to the ovaries are altered in PMOS. LH (luteinising hormone) is often disproportionately elevated relative to FSH (follicle-stimulating hormone), which further disrupts follicle development and ovulation. Genetic factors – PMOS can run in families, suggesting genes play an important role. Researchers are trying to identify which genes are involved, but because it’s a complex condition, it’s not surprising that it’s not a single gene, but that many genes are involved. What are the symptoms of PMOS? PMOS presents differently  from person to person. Some people have many symptoms; others have very few. Some symptoms are visible; others are internal. This variability is one of the reasons it takes so long to diagnose. Irregular or absent periods Irregular menstrual cycles are one of the hallmark features of PMOS. Because elevated androgens interfere with regular ovulation, periods can arrive unpredictably, sometimes weeks late, sometimes skipped altogether. Some people experience very long cycles (35 days or more); others may go several months without a period. What counts as irregular? Cycles shorter than 21 days or longer than 35 days, fewer than 8 periods per year, or periods that have no predictable pattern. If your periods have always been irregular  or if they became irregular after stopping the pill, PMOS is one of the first things worth looking into. Hormonal acne Hormonal acne is one of the most common and most distressing symptoms of PMOS. PMOS-related acne typically appears along the jawline, chin and lower cheeks. It may flare around the time of a period, or it may be persistent and seemingly random. It tends to involve deeper, more inflamed spots rather than surface-level break out, and it often doesn’t respond well to standard skincare. If you’ve tried everything on your skin and still can’t get it under control, your hormones are worth investigating. Unwanted hair growth (hirsutism) Elevated testosterone stimulates hair growth in areas where most women don’t typically grow coarse hair, the upper lip, chin, jaw, chest, stomach and inner thighs. This is called hirsutism, and it affects a significant proportion of people with PMOS. It can range from fine, barely noticeable hair to […]
