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 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
Some symptoms require treatment. Talk to your doctor about how to best manage menopause. Make sure the doctor knows your medical history and your family medical history. This includes whether you are at risk for heart disease, osteoporosis, or breast cancer.
