Tag: how is perimenopause diagnosed

If you’re in your 40s and suddenly notice irregular periods, brain fog, broken sleep, anxiety, night sweats or hot flushes that seem to appear out of nowhere, it’s natural to wonder: could this be perimenopause? And if you are wondering that, the next question often follows quickly: how is perimenopause actually diagnosed? One of the most frustrating things about perimenopause is that many people feel dismissed whilst searching for answers. You may arrive at a GP appointment with months of poor sleep, mood changes, heavy or unpredictable periods and symptoms that are affecting your work, relationships and confidence, and  be told to just wait and see. This guide explains how perimenopause is diagnosed in the UK, what happens if you are under 45, when blood tests are useful, when they are not, and how Hertility can help you get clarity. Quick facts: What is perimenopause? Perimenopause is the transitional phase leading up to menopause. During this time, the ovaries gradually become less responsive and start producing hormones such as oestrogen and progesterone less consistently. Importantly, hormone levels do not decline in a neat, predictable line. They can fluctuate significantly from one day to the next, and sometimes even within the same day. This hormonal turbulence is what can drive many of the symptoms people associate with perimenopause, including hot flushes, night sweats, mood changes, sleep disruption and cycle changes. Perimenopause can last for a few months, but for many people symptoms may persist for 7 to 9 years, sometimes longer, and they can change over time. It most commonly begins in the mid-40s, although it can start earlier. Menopause itself is confirmed retrospectively when you have gone 12 consecutive months without a period, assuming there is no other cause, such as pregnancy, medication or hormonal contraception. The average age of menopause in the UK is around 51, with a typical range between 45 and 55. Everything before that final period, while symptoms and cycle changes are happening, is considered perimenopause. Can perimenopause happen before 45? When menopause happens before the age of 45, it is called early menopause. When ovarian function reduces significantly before the age of 40, it is called premature ovarian insufficiency, or POI. This is less common than menopause at the average age, but it is not rare. Spontaneous early menopause affects around 5% of the population before age 45, while POI is estimated to affect around 1% of women under 40 and around 0.1% under 30. This distinction matters because early menopause and POI can affect more than periods. They can have implications for fertility, bone density, cardiovascular health, sexual health, emotional wellbeing, cognition and long-term hormone support. People under 45 may also find it harder to get their symptoms recognised because perimenopause is often associated with the late 40s and early 50s. But being younger does not mean your symptoms are irrelevant. It means they should be assessed carefully, with the right investigations and support. What are the symptoms of perimenopause? Because perimenopause is mainly diagnosed through symptoms, it helps to understand what those symptoms can look like. Perimenopause affects everyone differently. Some people have mild symptoms that come and go, while others experience symptoms that significantly affect sleep, mental health, work, relationships and day-to-day life. One of the earliest signs is often a change in your menstrual cycle. Your periods may become closer together, further apart, heavier, lighter, longer, shorter or simply less predictable than before. You might also notice spotting, missed periods or a cycle pattern that feels completely new for your body. Other common perimenopause symptoms include: There can also be symptoms that feel more surprising, such as dry eyes, brittle nails, dizziness, tinnitus, gum sensitivity or changes in taste and smell. Not everyone will experience all of these symptoms. What matters most is the pattern: new or worsening symptoms in midlife, particularly when they appear alongside changes to your menstrual cycle. Perimenopause should also be considered if someone develops new mood or anxiety symptoms in midlife, especially if they have no previous history of depression or anxiety. How is perimenopause diagnosed in the UK? In the UK, perimenopause is usually diagnosed through a clinical assessment. This means a doctor will ask about your age, symptoms, menstrual cycle, medical history, contraception use and how your symptoms are affecting your quality of life. If you are under 40: possible premature ovarian insufficiency should be investigated If you are under 40 and have symptoms that suggest menopause, this should not be brushed off as stress, lifestyle, anxiety or “just hormones” without proper assessment. In this age group, doctors should consider premature ovarian insufficiency, or POI. POI happens when the ovaries stop working normally before the age of 40. It is not the same as typical menopause in the early 50s, and it needs a different level of investigation and support. FSH blood testing is usually important if POI is suspected. Because hormone levels can fluctuate, diagnosis requires two high FSH results taken 4-6 weeks apart, alongside symptoms and menstrual changes. Your doctor may also consider other tests depending on your situation, such as thyroid function, prolactin, pregnancy testing, reproductive hormone testing, autoimmune screening or genetic investigations. This depends on your symptoms, medical history and whether you are trying to conceive. A timely diagnosis matters because POI can affect fertility, bone density and cardiovascular health. Hormone replacement therapy is often recommended until at least the average age of natural menopause, unless there is a medical reason not to use it. If you are under 40 and your periods have become irregular or stopped, especially alongside hot flushes, night sweats, vaginal dryness or fertility concerns, it is reasonable to ask directly whether POI has been considered. If you are 40 to 45: early menopause may need to be assessed Early menopause means menopause before the age of 45. Like POI, it can affect fertility, bone health, cardiovascular health and long-term wellbeing, so it is important not to simply dismiss symptoms. In this age group, a […]
