Causes of Early Menopause. Like in menopause that happens later in life, hormonal fluctuations are one of the root causes of early menopause. However, it is not fully known why these hormonal fluctuations are triggered earlier for some women.
Women who experience menopause symptoms. A woman reaches menopause when she has not had a menstrual period for one year, though symptoms often start earlier. They may include sleep issues, mood changes, trouble focusing, vaginal and urinary problems, hot flashes and night sweats. The severity of symptoms varies greatly from person to person, and many women do not need treatment for their symptoms, which tend to go away over time.
