Can obesity cause amenorrhea?

By Marta Barranquero Gómez B.Sc., M.Sc. (embryologist).
Last Update: 03/09/2022

Obesity or overweight, as well as a low body mass index (BMI), can have consequences on a woman's menstrual cycles. When the BMI is higher than 25, it is possible that a large amount of estrogens may be produced leading to alteration of the menstrual cycle, anovulation (absence of ovulation) and, therefore, absence of menstruation.
