For many women who enter menopause naturally, their menstrual cycle first becomes irregular. On average, it stops completely within about 4 years. Other symptoms that can happen during this time include: 1  Mood swings. 2  Lower sex drive. 3  Hot flashes. 4  Sweating. 5  Racing heart. 6  Headaches. 7  Vaginal dryness and soreness. 8  Painful sex. 9  Trouble sleeping.
Most of the symptoms associated with menopause actually happen during the perimenopause stage. Some women go through menopause without any complications or unpleasant symptoms. But others find menopausal symptoms debilitating, beginning even during perimenopause and lasting for years. The symptoms that women experience are primarily related to a lowered production of the female sex hormones estrogen and progesterone.
