Perimenopause is the span of years before menopause when a woman's
hormone levels and menstrual periods become irregular. Perimenopause has been
described as "going through menopause" or "being in menopause."
After 1 year of having no periods, a woman has reached menopause.
This is usually around age 50. In the years before menopause, changing hormone
levels, particularly estrogen and progesterone, cause perimenopausal symptoms.
These typically start in a woman's mid-40s, and they continue for a year or two
after menopause.
Some women have mild perimenopausal symptoms. Others have severe
symptoms that affect their sleep and daily lives. Symptoms can include:
- Unpredictable changes in menstrual pattern,
including heavier or lighter blood flows and shorter or longer
cycles.
- Hot flashes.
- Night sweats and sleep problems
(insomnia).
- Memory problems and lack of
concentration.
- Depression.
- Anxiety, irritability, and
mood swings.
- Heart palpitations.
- Vaginal itching or
dryness, causing discomfort during sexual activity.
- Decreased sex
drive (libido).
