Menopause is defined by the loss of ovarian function and absence of menstrual period for at least a year.

The average age of menopause is 50.

If menopause is experienced before the age of 40, it is called premature or early menopause and calls for medical attention. It occurs in about 1% of female population.

Menopause transition years are called climacterium or perimenopause, and are the period of time before and after the loss of ovarian function.

The climacteric or perimenopausal period is the period before and after the definitive end of ovarian function.

Symptomology


Most common and bothersome symptom following menopause is hot flushes

They first appear during perimenopause, and the majority of women experience them for many years.

Fast heartbeat, vaginal dryness, loss of sexual drive, weakness, vertigo, faint, headaches, sleep disturbances, skin wrinkles, mood swings, dysuria and breast atrophy are other distressing effects.

Some of these effects are related to hypoestrogenaemia, the sudden drop in estrogen levels due to changes in the thermoregulatory centre of the hypothalamus.
