I spent nearly ten years working as a specialist respiratory nurse, confident that I understood obstructive sleep apnoea.
It turns out I had been taught to look for it in the wrong people.
Like many clinicians, I saw sleep apnoea largely through the lens of weight and lifestyle. The classic picture was clear in my mind: overweight, middle-aged men, loud snoring, witnessed apnoeas. That was the lens I had been trained to look through, and I had no real reason to question it.
That changed when I started training as an ADHD coach.
I came across research I had never encountered in my nursing career. Rates of obstructive sleep apnoea rise significantly during perimenopause. And it overlaps with ADHD far more than most clinicians realise.
For women with ADHD who are entering perimenopause, there is a possibility that three separate but overlapping things are happening at once. ADHD, often undiagnosed for decades.
Perimenopause, changing everything hormonally. And obstructive sleep apnoea, quietly developing in the background. None of which may be fully recognised or treated.
ADHD and sleep apnoea share so many features: exhaustion, poor concentration, mood changes, irritability. Add in the hormonal changes of perimenopause, which reduce upper airway tone and increase sleep apnoea risk, and the picture becomes genuinely difficult to untangle, even for healthcare professionals who are looking closely.
In women, sleep apnoea rarely looks like the textbook version. It is far more likely to show up as persistent fatigue, broken sleep, insomnia, or low mood. Symptoms that are very easily explained away as something else entirely.
As oestrogen and progesterone decline, upper airway tone decreases. This is not a lifestyle issue. It is a hormonal one. And it 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 is developing underneath, undetected.
If we are only treating one piece of the picture, we will keep missing the rest of it.
If you are a woman with ADHD in perimenopause and something still does not feel right despite treatment, sleep apnoea is worth asking about. You do not have to snore. You do not have to fit the classic profile. Speak to your GP and ask for a referral to a sleep clinic. You deserve to get answers.
We need more awareness around this, both within the clinical community and for the women living with it every day.
Has this resonated with you or someone you know? I would really like to hear your experiences.
