Also called: Change of life

Menopause is the time in a woman's life when her period stops. It usually occurs naturally, most often after age 45. Menopause happens because the woman's ovary stops producing the hormones estrogen and progesterone.

A woman has reached menopause when she has not had a period for one year. Changes and symptoms can start several years earlier. They include

  • A change in periods - shorter or longer, lighter or heavier, with more or less time in between
  • Hot flashes and/or night sweats
  • Trouble sleeping
  • Vaginal dryness
  • Mood swings
  • Trouble focusing
  • Less hair on head, more on face

Menopause is not a disorder. Most women do not need treatment for it. However, if symptoms are severe, medicines may help. After menopause, women are more vulnerable to bone loss and heart disease. Exercise and eating right can help keep women healthy as they age.
