Hormones and anxiety: the links that get missed

There are two patterns I have learned to ask about directly, because otherwise they rarely come up.

The first is anxiety that runs on a timetable. Three good weeks, then a week where everything feels thin and sharp, then three good weeks again. The second is anxiety arriving in someone's forties who has never had it before, often with broken sleep and a shorter fuse alongside it.

Neither pattern proves anything on its own. But both are worth a question that often goes unasked, because the appointment was booked about anxiety and nobody thinks to bring up periods.

The short version

• Generalised anxiety disorder is more common in women than men in England: 8.9 per cent compared with 5.7 per cent in the most recent national survey. Hormones are one possible thread in that, not the whole story.
• If your symptoms cluster in the two weeks before your period, that has a name and a treatment pathway.
• NICE recognises anxiety arising as a result of the menopause and says to consider CBT for it.
• An overactive thyroid can look almost exactly like anxiety, and a blood test settles it.

What the numbers show, and what they do not

In the 2023/4 Adult Psychiatric Morbidity Survey, one in five adults in England had a common mental health condition, and the rate was higher in women (24.2 per cent) than men (15.4 per cent). For generalised anxiety disorder the figures were 8.9 per cent of women and 5.7 per cent of men. Among working age adults, the overall gap has been consistent since the survey began in 1993.

I would be cautious about reading that as a hormone story. A gap like this has many possible parents: social circumstances, caring load, how likely each group is to report symptoms, as well as biology. "It is your hormones" is not a diagnosis, it is a hypothesis, and the useful thing about a hypothesis is that you can test it.

When anxiety runs on a monthly timetable

Premenstrual syndrome is not only bloating and sore breasts. The RCOG's own guideline describes PMS as covering depression, anxiety, irritability, loss of confidence and mood swings, alongside the physical symptoms. It puts the figures at around four in ten women getting premenstrual symptoms, with 5 to 8 per cent of those experiencing severe PMS. Its patient information puts the severe end at between 2 and 4 in 100 women, bad enough to stop them getting on with daily life.

That is a lot of people whose anxiety has a shape and has been called just stress.

Both the NHS and the RCOG advise the same unglamorous test: keep a symptom diary across two full menstrual cycles. Date, what you felt, severity out of ten. A pattern on paper is much harder to dismiss than a feeling you are trying to describe in ten minutes.

If a pattern emerges, treatment is not a shrug. The RCOG says CBT is known to help PMS symptoms and should be offered as an option, and the NHS lists it alongside hormonal treatment such as the combined pill, and antidepressants. A small number of women have a much more intense form, premenstrual dysphoric disorder, which deserves proper attention rather than another year of tolerating it.

Perimenopause, the one that gets missed

The clinical framing here has moved, and a lot of people have not been told. NICE's menopause guideline explicitly says to consider CBT to relieve low mood or anxiety that arises as a result of the menopause. Anxiety is in the guideline. It is not something you have invented.

You may not get the blood test, and that is not a brush-off

For otherwise healthy women over 45, NICE says perimenopause should be diagnosed on symptoms and an irregular cycle, without laboratory tests. Blood tests are reserved for younger women, roughly 40 to 45 with symptoms, or under 40 where menopause is suspected. NICE also advises against using an FSH test to diagnose menopause in women on combined hormonal contraception or high-dose progestogen, because it will not tell you what you want to know.

Being told you do not need a blood test is not the same as being told nothing is happening.

What NICE actually says about antidepressants

NICE's position here is narrower than it is sometimes taken to be. It says there is no clear evidence that SSRIs or SNRIs ease low mood in menopausal women who have not been diagnosed with depression, and that they should not be routinely offered as first-line treatment for hot flushes and night sweats alone. Both of those points are about low mood and flushes, not anxiety. If one is suggested to you, asking what it is aimed at is a fair question, not an awkward one.

There is a practical problem hiding in all of this, which is timing. If your worst stretch is the week before your period, or a run of broken nights in the middle of perimenopause, an appointment six weeks away lands after the window has closed. It is one reason we built brightloaf around therapy in 20 minutes rather than an hour you have to clear the diary for: short enough to book in the week you actually need it, and again next month.

The blood test that is worth doing

An overactive thyroid produces nervousness, anxiety and irritability, palpitations, trembling, poor sleep, heat sensitivity and weight loss despite a decent appetite. Read that list back and you can see the problem. It is uncommon, but cheap to exclude, and it would be a grim way to spend a year in therapy for something a blood test would have caught. If your anxiety is new and arrived with physical changes, ask.

What to do with this

Track it for two cycles, or three months if your cycles are irregular. Take the pattern to your GP rather than the feeling, and say the timing out loud, because we do not always ask. There is more on framing that conversation in how to get the most from a short GP appointment, and on whether to go at all in when to see your GP about anxiety.

None of this means your anxiety is only hormonal. But a pattern that repeats is information, and information is the one thing a ten minute appointment is short of.

This is general information and not a substitute for personal medical advice. If you are in crisis or feel unsafe, call 999 or go to A&E, or call Samaritans free on 116 123. brightloaf is not a crisis service.
