Why am I gaining weight during perimenopause?

Weight gain in perimenopause: one cause or several?

Bring a timeline, not a theory

A clinician who knows your history is the person to sort out which factors apply to you, and the most useful thing you can bring is a timeline. The steps below say what to put in it.

What to look at

The Cleveland Clinic page on perimenopause covers the stage, its signs and its treatment in one place. The Menopause Society page on hot flashes covers another symptom of the same stage, so note what else has changed alongside your weight.

A skeptical reading asks whether "perimenopause" is being used to explain everything. Timing, sleep, stress, medicines and other health conditions are all worth ruling in or out before settling on one cause.

What to put in your timeline and ask at the visit

Note when the weight change began and what else changed around then.
Bring a list of your current medicines and supplements to your appointment.
Ask whether any tests or other causes should be checked before attributing the change to perimenopause.

A note on expertise

A single-cause answer to weight gain in perimenopause deserves a second look, and a clinician who knows your history should guide decisions about your care.
