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.
Menopause is the time in a woman's life when menstrual periods permanently stop, also called the change of life. Menopause symptoms include hot flashes, night sweats, irregular vaginal bleeding, vaginal dryness, painful intercourse, urinary incontinence, weight gain, and emotional symptoms such as mood swings. Treatment of menopausal symptoms varies, and should be discussed with your physician.
