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.
The average age that women go through the menopause is 52, but a woman could start to experience menopausal symptoms between the ages of 45 and 55. The symptoms can last two to five years. Medical conditions can cause the menopause to happen much earlier, sometimes in a womanâs 20s or, in extreme cases, in childhood.
