The age range for perimenopause can vary widely from woman to woman, but it typically starts in the late 30s or early 40s and can last anywhere from a few months to several years. Perimenopause is the transitional period leading up to menopause when a woman's hormone levels begin to fluctuate and her menstrual cycle becomes irregular. During this time, a woman may experience a range of symptoms including hot flashes, mood changes, sleep disturbances, and vaginal dryness.
Perimenopause ends when a woman has began menopause, which is defined as 12 consecutive months without a menstrual period. Once a woman has started menopause, her ovaries have stopped releasing eggs, and she can no longer become pregnant naturally.
It is important for women to talk to their healthcare provider about their individual symptoms and needs during perimenopause, as there are a range of treatment options available to help manage symptoms and promote overall health and well-being during this time.
