What’s Really Happening During Perimenopause

It isn’t one thing. It’s many things changing.

Your sleep changes. Your focus feels different. Your mood shifts. Your cycle may stop behaving the way it used to. Perimenopause can affect different women in very different ways. Understanding what’s happening starts with looking beyond a single symptom, and seeing the bigger picture.

Perimenopause is a transition

Your period isn’t the only thing that can change.

Sleep, concentration, mood, temperature regulation, energy and menstrual patterns can all shift during the menopausal transition. But symptoms vary widely from person to person, which is one reason understanding what’s happening can feel so complicated.
