Perimenopause: 'I don't recognize myself.' What is happening to you and when to seek advice

So, what is perimenopause?

Menopause, in reality, is a single day: the date of your last period. And the curious thing is that we can only confirm it by looking back, once twelve months have already passed without menstruation.

Perimenopause is everything that comes before: the years of transition during which the ovary stops working regularly. And here is the key point I want you to take away: hormones do not drop all at once or in a straight line. They go up and down, they fluctuate. That rollercoaster explains a large part of what you are feeling.

It usually begins around the mid-forties, but the range is enormous. Some women notice it earlier and others much later. There is no single 'correct' way to experience it.

The signs that tend to appear

The first thing is usually the period itself: it comes earlier, it comes later, it becomes heavier or lighter, cycles shorten or lengthen. That change in menstrual pattern is one of the most characteristic clues.

From there, a bit of everything can appear: hot flushes and sweats, especially at night; sleep that no longer feels as restful; mood changes, irritability or increased anxiety; that 'brain fog' that makes it hard to concentrate or find the right words; vaginal dryness or discomfort during intimacy; and changes in the body, with a greater tendency to accumulate fat around the abdominal area.

But be mindful of one thing: not all women experience all of this, nor with the same intensity. I have patients who barely notice anything and others whose quality of life is genuinely affected. Both situations are absolutely normal.

'Can't you just run a hormone test and settle the question?'

It is, quite probably, the question I am asked most often. And I understand the impulse: a number feels reassuring. But here I have to be honest with you.

In a woman of the typical age and with compatible symptoms, the diagnosis of perimenopause is primarily clinical. That is to say, we make it by listening to your story, not by chasing a figure. And because hormones fluctuate so much from one day to the next, a single blood test can mislead us: today it comes back 'normal' and the following week, abnormal. That is why clinical guidelines do not recommend basing the diagnosis on a single hormonal measurement in the majority of cases.

When does it make sense to request tests? When symptoms appear early, when there is genuine uncertainty, or to rule out other conditions that can masquerade as menopause. And I want to pause here, because I think it matters.

Let's not assume that 'everything is menopause'

Fatigue, mood changes and poor sleep are tremendously non-specific symptoms. They could be perimenopause… or they could be the thyroid, an iron deficiency, a sleep disorder or a particularly stressful period in life.

I have seen women drag on for months of fatigue attributed to 'age' that was actually concealing an underactive thyroid or rock-bottom ferritin levels. That is why a thorough assessment looks at you as a whole person, not just at one organ or one isolated hormone.

And when is it worth making an appointment?

Consult a doctor if symptoms are affecting your quality of life, sleep, or motivation. Also consult if you have any bleeding that concerns you: very heavy periods, bleeding between periods, or — and this is important — any bleeding that appears after you have already gone twelve months without a period. That last one always needs to be evaluated.

And consult, simply, if you have questions. You do not need to wait until you feel unwell to ask for information. Understanding what is happening to you is, in itself, a way of taking care of yourself.

What I really want you to take away from this

Perimenopause is not a disease. It is a natural stage of life. But the fact that it is natural does not mean you have to live through it in silence or resign yourself to feeling unwell.

There are lifestyle measures that help, ways to treat symptoms, and, in some very specific cases and always on an individualised basis, hormonal treatment options that you can discuss with your doctor. The key is neither fear nor resignation: it is information and making decisions together.
