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 ovaries
stop producing 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
