Mood swings in menopause

You snap at your partner over something small and startle yourself. An advert brings you to tears. And an hour later it has passed. For many women, menopause does not announce itself with hot flushes. They notice first that their fuse is getting shorter. This page explains why your mood swings so much, how it differs from depression, and what actually helps.

How women describe it

"My fuse is so much shorter than it used to be."

"I burst into tears over nothing."

"One moment I'm fine, the next I'm boiling with rage."

"I don't recognise myself anymore."

Sound familiar? You are far from alone. Mood swings are among the most reported symptoms in menopause, yet hardly anyone connects them to hormones straight away.¹ Part of that is because women expect sadness, while for many it starts with irritation and anger instead. That anger is the most underrated symptom of the lot.

What happens in your head

Oestrogen does more than regulate your cycle. In your brain it also supports serotonin, the messenger that keeps your mood steady. When oestrogen falls, an enzyme in the brain breaks serotonin down faster, so your mood loses some of its buffer.¹ Progesterone plays a part too: it is converted in the brain into a substance that has a calming effect through GABA, a kind of natural brake on tension and irritability. When progesterone drops away, part of that brake goes with it.

In perimenopause these hormones do not fall smoothly. They swing sharply from one day to the next, sometimes from one hour to the next.² It is precisely that swinging, rather than the low level itself, that makes your mood so changeable. That is why symptoms are often strongest in perimenopause, and why for many women they ease once hormones settle after menopause.

Mood swings rarely travel alone, either. Poor sleep, night sweats, fatigue and anxiety all become more common in the same phase, and each one puts extra strain on your mood. That is why some weeks feel heavier than others.

Mood swings or depression: the difference

Many women wonder whether this is still "just the hormones" or something more serious. That question deserves an honest answer, because it is true on both sides.

The difference is in the pattern. Mood swings fluctuate: after a good night or a good afternoon, the cloud clears again. Depression does not. Your mood stays low, day after day, for longer than two weeks, and you lose interest or pleasure in things you used to look forward to.

At the same time, perimenopause is a vulnerable period, and that should not be waved away. During this phase women are roughly one and a half to three times more likely to experience depression than before, including women who never had it before. Dismissing your symptoms as something that simply comes with the territory is not always fair.

If your mood stays low for more than two weeks, if you no longer enjoy anything, or if you feel hopeless, seek support; this responds well to treatment. If you are having thoughts of harming yourself, do not wait: contact your GP, or call a crisis line. You do not have to carry this on your own.

The impact on your relationships and work

Mood swings rarely stay inside your own head. You react more sharply towards your partner or your children, and feel guilty afterwards. At work it takes more effort to hold your patience or stay calm in a difficult meeting. This is not a character flaw and not a sign that you can no longer cope. It is a body adjusting to a new hormonal balance. Explaining to the people around you what is going on, and naming that it surprises you too, often takes some of the tension out of the room.

What you can do yourself

There is no pill that flattens your mood. There are habits with solid evidence behind them, and they support your general health at the same time.³ Many women find it steadying to map their pattern first: for a week or two, note your sleep, your hot flushes, your stress and the moments you tip over. It makes your triggers visible, and shows you that it fluctuates.

• Move regularly. Aim for around 150 minutes of moderate activity per week, such as brisk walking or cycling. Movement has a proven calming effect on mood and stress.
• Protect your sleep. Too little sleep makes you more irritable and low. If night sweats wake you, discuss them with a doctor, because they are treatable. There is more on this under sleep problems.
• Take the pressure off. Real breaks, fewer things at once and time to recover count as treatment, not luxury. Keep pushing until the tension builds up and everything hits harder.
• Watch alcohol and caffeine. Both feed restlessness and disrupt your sleep. A glass of wine in the evening relaxes you briefly but often leaves you more irritable the next day.
• Talk about it when it gets heavy. Cognitive behavioural therapy works well for low mood and anxiety, and can improve your sleep at the same time.

Does hormone therapy help?

Here the advice differs from some other menopause symptoms. For a low or changeable mood that arises as part of menopause, hormone therapy can genuinely help. Guidelines recommend considering it in that case.^4,5,6

Clinical depression is different. It is treated with talk therapy and, if needed, antidepressants, in menopause as at any other time. So antidepressants are not the first choice for a menopause-related low mood, unless there is genuine depression.

Indirectly, hormone therapy often helps as well. If hot flushes and night sweats keep you awake less, you wake up with a longer fuse. A care provider who knows menopause well can look at what is useful and safe in your specific situation.

Where to find help

Are the symptoms still heavy, or steering your relationships, your work or your confidence? You don't have to figure this out alone.

Your GP (huisarts) is a good first stop. With a blood test they can rule out other causes, such as a thyroid problem or an iron or vitamin B12 deficiency, refer you to a gynaecologist or a psychologist if needed, and take the first steps with you. Some Belgian hospitals also run a dedicated menopause clinic.
