Perimenopause, understood

Hot flashes at 3am. Brain fog that won't lift. Anxiety from nowhere. What if it's not just stress?

Perimenopause is one of the most significant transitions of your life — and most women navigate it without the right information or anyone who truly understands.

Evainne is being built to help you track your symptoms, understand what's happening, and walk into your next appointment knowing exactly what to say. The symptoms are real. You are not imagining it, and you are not falling apart.

Understanding perimenopause

You're not imagining it. It's real.

Perimenopause is the years-long transition before menopause, when shifting hormones can affect your body and mind in ways no one warned you about. Here's what the evidence says.

2–8 yrs
It lasts longer than you'd think
Perimenopause averages about four years, but can range from two to eight — and symptoms often begin well before periods stop.
80%
Hot flashes are the norm
Up to 80% of women experience hot flashes during this transition. If it's happening to you, you're in the overwhelming majority.
CBT
Evidence-supported tools exist
Cognitive behavioural therapy is evidence-supported for reducing how often some symptoms occur — one of several approaches worth discussing with your provider.

Evainne shares general, evidence-supported information and is not a substitute for medical advice. Always consult your own healthcare provider about your symptoms and options.
