WHAT IS PERIMENOPAUSE?
Perimenopause, or pre-menopause is a transitional stage of two to ten years before complete cessation of the menstrual period. Its average duration is six years, and can appear in women from 35 to 50 years of age. This has not been a stage of women's lives much talked about, and a woman can find herself experiencing puzzling changes, and not know why. What is actually going on is a gradual decrease of estrogen. The manifestations of perimenopause can vary. Here are some of the most commonly reported ones:
