The feeling that a breath does not complete. Yawning and sighing repeatedly to try to get one that satisfies. It is frightening in a specific way, because it sounds like your heart or your lungs — and the worst possible response to it is to decide for yourself that it is anxiety.

Where we stand: Menova is an independent publication. We sell no supplements or breathing programmes, we are not your doctor, and this is general education, not a diagnosis. Breathlessness is a symptom to be assessed, not one to explain away.

Get this checked before reading the rest

New or worsening breathlessness needs a clinician. Not because it is usually serious, but because the things it can be are treatable and several of them are missed in women specifically.

Call emergency services for breathlessness that comes on suddenly and severely, breathlessness with chest pain or pressure, breathlessness with a swollen, painful calf, coughing blood, fainting, or blue lips.

Be seen promptly, not eventually, for breathlessness that is new, getting worse over days or weeks, wakes you at night, comes on at rest, or comes with ankle swelling.

And say it plainly. "I get breathless going upstairs, which is new since March" gets investigated. "I've been feeling a bit anxious" does not.

The things it commonly is

Almost all of these are things this site covers because they imitate the transition — and all are treatable.

Iron deficiency. The commonest and most under-checked. Breathlessness on stairs, exhaustion, palpitations, feeling cold — and periods often get heavier before they stop. Ferritin falls before haemoglobin does, so "your bloods were fine" is not enough. See low ferritin in perimenopause and when iron is not the answer.

Thyroid disease, in either direction, which peaks in this age group — see perimenopause versus thyroid.

Asthma, which can appear or worsen around the transition and is frequently mistaken for being unfit — see asthma and menopause.

Sleep apnoea, which is under-diagnosed in women and presents differently from the stereotype — see menopause and sleep apnoea.

Heart rhythm problems. Atrial fibrillation becomes more common in this decade and is often first noticed as breathlessness or fatigue rather than a dramatic palpitation — see atrial fibrillation in midlife women and palpitations in perimenopause.

Blood clot on the lung. Uncommon, serious, and the one to name if you are on hormone therapy, have recently flown long-haul, had surgery, or have a swollen calf. Do not sit on this — see HRT and blood clot risk.

Heart disease. Women's cardiac symptoms are frequently atypical — breathlessness, fatigue and jaw or back discomfort rather than crushing chest pain — and are dismissed more often. See heart health in menopause.

Long COVID, which commonly includes breathlessness and overlaps confusingly with the transition — see long COVID and menopause.

Then there is the pattern with a name

If you have been assessed and those have been excluded, there is a recognised pattern that fits what a lot of women describe.

It does not behave like lung or heart breathlessness. The distinguishing features people report:

  • It is worse at rest and often better during exercise, which is the opposite of cardiac or respiratory breathlessness
  • The problem is the in-breath, not running out of air — a breath that does not feel finished
  • Frequent sighing and yawning, to try to complete one
  • It comes in waves over days, rather than steadily worsening
  • You can distract yourself out of it, at least briefly
  • Nothing is wrong with your oxygen levels

Anxiety is genuinely part of this for many people, and anxiety is itself a recognised feature of the transition rather than a character flaw — see mood and anxiety in menopause.

But the order matters. Assessed first, then this. Not the other way round, because "it's just anxiety" is exactly how women's cardiac and respiratory problems get missed.

Why it becomes self-sustaining

Worth understanding, because it explains why trying harder makes it worse.

Sighing repeatedly to get a satisfying breath blows off carbon dioxide. Lower carbon dioxide produces light-headedness, tingling in the hands and around the mouth, and a stronger sense of not getting enough air — which prompts another big breath. The harder you try to fill your lungs, the worse the sensation gets.

That is why the useful advice is counter-intuitive: the fix is a smaller, slower breath out, not a bigger one in.

What actually helps, once it is been checked

  • Breathe out longer than you breathe in. Four in, six out, through the nose, for a few minutes. Do not take a big breath first
  • Stop the sighs when you notice them. Each one perpetuates the loop
  • Nose, not mouth, and low in the belly rather than high in the chest
  • Do it when you are fine, not only when it happens. It works as a practised habit, not as a rescue
  • Physiotherapy for breathing pattern disorder exists and is under-referred. Ask about it explicitly — a specialist physiotherapist can retrain this properly
  • Treat the sleep, because everything here is worse on broken nights — see menopause insomnia
  • Caffeine and alcohol both make it more likely — see caffeine and menopause
  • CBT has a reasonable evidence base for the anxiety component — see CBT for menopause

Do not use a paper bag. It is dangerous advice that persists, and it can mask a serious cause.

Does hormone therapy help?

There is no good evidence that hormone therapy treats breathlessness, and it should not be started for that. If it improves sleep, hot flashes and anxiety, some women find this eases as a consequence — that is a plausible indirect effect, not a treatment claim.

One thing to know if you are already on it: new breathlessness on hormone therapy is a reason to think about clot risk and get seen, not a reason to assume the transition. See HRT and blood clot risk.

What to say

"I keep feeling like I can't get a full breath and I'm sighing constantly. It's newer than the last few months. Before we call it anxiety, could we check ferritin, thyroid and my heart rhythm — and I'm on HRT, so should we think about a clot?"

That describes the symptom precisely, gives a timeline, names the tests, and raises the one thing that must not be missed.

Our free 30-day symptom tracker shows whether it tracks anything, the free printable visit prep sheet keeps it to one page, and our free blood test sheet covers what should be checked. The free 2-minute Menova self-check organizes your wider symptom picture — no account, not a diagnosis, and your answers never leave your device.

This article is general education, not medical advice or a diagnosis. Breathlessness requires assessment by a licensed clinician before it is attributed to anxiety or to menopause. Sudden or severe breathlessness, breathlessness with chest pain, or breathlessness with a swollen painful calf requires emergency assessment.
