Perimenopause, or menopause transition, is the stage of a woman's reproductive life that begins several years before menopause, when the ovaries gradually begin to produce less estrogen.
Menopause is the permanent end of menstruation. It's a turning point, not a disease, but it can have a big impact on a woman's wellbeing.
Causes & Symptoms
Natural and expected hormone changes cause perimenopause, menopause, and postmenopause.
