Menopause is not a sudden change. During the months or years before menopause (perimenopause), your ovaries start to run out of eggs. Your body makes less estrogen and progesterone. This may bring on symptoms, such as hot flashes. You’ve reached menopause when you have not had a period for 1 year. From that point on, you are in menopause.
Perimenopause
In the years leading up to menopause, your ovaries make less estrogen. You release fewer eggs and your periods become less regular.
Symptoms you may have
-
Heavier or lighter periods
-
Longer or shorter time between periods

Hot flashes

Mood swings or depression

Night sweats

Insomnia

Vaginal dryness, which may make having sex uncomfortable or painful
-
Urinary changes, such as incontinence or urinating more often

Postmenopause
After menopause, you make very little estrogen. As a result, the uterine lining doesn't get thicker, and your periods have ended.

Surgical menopause
Menopause occurs if you have your uterus removed. But symptoms of menopause happen only if the ovaries are also removed. This causes a quick drop in the amount of estrogen and progesterone. This drop causes sudden and severe symptoms.
