Perimenopause anxiety: why it happens and what helps

"It's just stress."

What it sounds like

• "My heart pounds for no reason, then I'm hot."
• "I lie awake at 3am running through everything."
• "I snap at people I love, then cry about it."
• "I used to handle this much. Now I can't."

Mood swings, irritability, tearfulness, anxiety, low mood and a loss of motivation and energy are the most common mood symptoms in perimenopause. They're symptoms. They are not a character flaw, and they are not "just stress".

Why it happens now

"You've always been a worrier."

Perimenopause is when hormone levels rise and fall unpredictably. Ontario Health's standard lists changes in mood, including anxiety and depressive symptoms, among its symptoms, and says perimenopause is a particularly vulnerable time for depressive symptoms, even in people with no history of depression. It also says these symptoms are often under-recognized and undertreated.

Two things feed it. Hot flashes can come with anxiety or palpitations, so the body can feel panic before the mind has a reason. And mood symptoms get worse when sleep is broken, which in perimenopause it often is.

Why it's worse at night

"Just try to relax."

Night sweats are a big cause of broken sleep in perimenopause, and waking at 3am with a racing heart and a racing mind can come together. Ontario's standard says hormone therapy may improve sleep in people who have hot flashes and night sweats, because those symptoms are an important cause of the disruption. Cognitive behavioural therapy for insomnia and aerobic exercise have also shown benefit for sleep.

What helps, plainly

• If hot flashes and night sweats come with it. Treating them is the first step. Hormone therapy is offered first line for them, after your own risks are assessed, and there are non-hormonal prescription options if hormones aren't for you.
• For low mood in perimenopause that isn't diagnosed depression, Ontario's standard lists hormone therapy and cognitive behavioural therapy as options, alone or together. CBT can be online, in a group or self-guided.
• For an anxiety disorder or diagnosed depression, the standard points to their own care pathways. If that's what's going on, we say so plainly, and talk through the right next step with you.

Straight answer: nobody can promise hormone therapy will fix anxiety. What we can do is look at the whole picture, the sweats, the sleep, the timing, your history, and tell you plainly which options fit.

When to book, and when not to wait

• The anxiety is new, or newly worse, in your 40s or early 50s.
• It comes with night sweats, broken sleep or changing periods.
• It's getting in the way of work, sleep or home.
