Sleep Apnoea, ADHD and Perimenopause: The Connection That Too Many Women Are Missing

Many women with ADHD who are going through perimenopause are struggling with exhaustion, broken sleep and a feeling that something is not right, and not getting answers. One piece of the picture that is frequently missed is obstructive sleep apnoea. I spent nearly ten years as a specialist respiratory nurse, confident I understood this condition. It turns out I had been taught to look for it in the wrong people.

What I thought I knew

My understanding of obstructive sleep apnoea was built around a very specific picture: overweight, middle-aged men, loud snoring, witnessed apnoeas, daytime sleepiness. That was the clinical lens I had been trained to look through, and for nearly a decade, I had no reason to question it.

Like many clinicians, I saw sleep apnoea largely through the lens of weight and lifestyle. What I did not fully appreciate was how often it shows up alongside ADHD, and how significantly the risk changes for women during perimenopause.

That understanding shifted when I began training as an ADHD coach. The more I read, the more I realised there was a significant gap in what I had been taught, and in what many women were being told about their own health.

"If we are only treating one piece of the picture, we will keep missing the rest of it."

Three things that can interact at once

For women with ADHD who are entering perimenopause, there is a possibility that three separate but overlapping conditions are happening simultaneously, and none of them may be fully recognised or treated.

1. ADHD, often undiagnosed for decades

2. Perimenopause, changing everything hormonally

3. Obstructive sleep apnoea, quietly developing in the background

Each of these conditions is complex in its own right. Together, they create a clinical picture that is genuinely difficult to untangle, even for healthcare professionals who are looking closely.

Why it is so easy to miss

ADHD and obstructive sleep apnoea share a striking number of features. When you are trying to work out what is driving what, the overlap makes it very hard to see clearly.

Both conditions, alongside perimenopause, commonly present with: persistent exhaustion, poor concentration, mood changes, irritability, broken sleep, low mood, insomnia, and a general feeling of being unrested.

To complicate things further, obstructive sleep apnoea in women is frequently underdiagnosed because it does not always look like the classic presentation. In women, it is far more likely to show up as persistent fatigue, low mood, broken sleep, or insomnia. These are symptoms that get very easily explained away, often attributed to stress, burnout, depression, or simply what perimenopause feels like.

The hormonal connection

As oestrogen and progesterone decline during perimenopause, upper airway tone decreases. This is the physiological mechanism that increases the risk of obstructive sleep apnoea developing at this stage of life. It is not a lifestyle issue. It is a hormonal one.

This means that women who have spent years managing ADHD symptoms, perhaps without even knowing they had ADHD, may find things becoming significantly harder during perimenopause. Not only because of the hormonal changes themselves, but because something else may be developing underneath, undetected.

"You do not have to snore loudly to have obstructive sleep apnoea. You do not have to fit the classic profile. In women, the presentation is often subtler and more easily dismissed. If something does not feel right, speak to your GP and ask for a referral to a sleep clinic. You deserve to get answers."

What this means in practice

I am not suggesting that every woman with ADHD and perimenopause has sleep apnoea. But I do think we need better screening, and a much clearer understanding of how these conditions interact.

If you have ADHD and you are in perimenopause, and you are struggling with exhaustion, broken sleep, or a feeling that something still is not right despite treatment, it is worth asking whether sleep apnoea has been properly considered. Speak to your GP and ask for a referral to a sleep clinic. You do not have to snore. You do not have to fit the classic profile.

If you are a clinician supporting this group of women, it may be worth revisiting the screening questions you use and the assumptions behind them. The classic picture of sleep apnoea was largely built on research conducted in men. Women deserve a more complete assessment.

This is exactly the kind of conversation I have been having with others working in this space, and it has reinforced for me just how much more awareness we need around this, both within the clinical community and for the women living with it every day.

When we treat only one piece of the picture, we will keep missing the rest of it.

If this resonates, or you have concerns about your own sleep, speak to your GP and ask for a referral to a sleep clinic. You deserve to get answers.
