perimenopause is the stretch of time leading up to menopause, when your body gradually shifts away from a regular monthly cycle. it is not a single event but a process, often unfolding over several years, and it can look quite different from one person to the next.
what does perimenopause actually mean?
the word itself simply means "around menopause". menopause is defined as the point twelve months after your last period, so perimenopause is everything that happens in the lead up to that point. during this time, your ovaries slowly produce less oestrogen and progesterone, but not in a smooth, predictable decline. levels can rise and fall unevenly from month to month, which is part of why symptoms can feel so unpredictable.
when does it usually start?
perimenopause most commonly begins in your forties, though for some people it can start earlier, in their late thirties. the length of this transition varies a lot. for some it lasts a couple of years, for others closer to a decade. there is no single "normal" timeline, and your own experience will not necessarily match a friend's or family member's.
common changes you might notice
- periods becoming irregular: shorter, longer, lighter, heavier, or closer together
- changes in sleep quality
- hot flushes or night sweats
- mood changes, including increased irritability or low mood
- difficulty concentrating, sometimes described as brain fog
- changes in weight or where weight is carried
- vaginal dryness or changes in libido
not everyone experiences all of these, and the intensity varies enormously. some people move through perimenopause with barely a ripple, while others find it genuinely disruptive to daily life.
why understanding it matters
because the changes of perimenopause can be gradual and easy to mistake for stress, ageing, or "just having an off few months", many people do not realise what is happening until well into the process. recognising the signs early can make it easier to seek support, make informed choices about lifestyle and nutrition, and feel less alone in what is a completely normal, natural transition.
looking after yourself through the transition
small, sustainable habits like steady meals, regular movement, enough sleep where possible, and stress management can support general wellbeing during this time, even though they will not stop the hormonal changes themselves. some people also look at their nutrition more closely during perimenopause, including habits like seed cycling, as one small part of a broader, supportive routine.
when to speak with a gp
if your symptoms are significant, persistent, or getting in the way of daily life, it is worth booking an appointment with a gp. they can talk through what you are experiencing, rule out other causes, and discuss the full range of evidence based options available, including hrt, so you can make a decision that feels right for you.
