What is premature menopause?

Menopause is the time in a woman's life when menstrual periods cease. It is defined medically as the absence of menstrual periods for 12 consecutive months. The average age for a natural menopause is 51. Sometimes, menopause occurs earlier, due to diseases, genetic factors, or surgery. There is also a wide variation among women regarding the timing of normal menopause.

What causes early menopause?

As mentioned previously, menopause before the age of 40 are considered to be in premature, or early, menopause. One medical causes of premature menopause is known as premature ovarian failure. Technically, premature ovarian failure is not the same as premature menopause. In premature ovarian failure, the ovaries stop functioning normally before the age of 40. Women with premature ovarian failure may still occasionally have menstrual periods, but they typically experience infertility. Premature ovarian failure is usually accompanied primary ovarian insufficiency. Premature ovarian failure is usually accompanied by the symptoms of premature menopause.

Premature menopause can also be caused by treatments for cancers or other conditions that involve chemotherapy and/or radiation therapy to the pelvis. These treatments can damage the ovaries and result in ovarian failure.

Surgery to remove the ovaries, either for benign or malignant conditions, results in premature menopause if both ovaries are removed. Surgery to remove the uterus results in menopause only in the sense that menstrual bleeding does not occur. In that case, the ovaries will continue to produce hormones.

Other infrequent causes that may lead to premature menopause include drugs, chronic diseases, pituitary and hypothalamic tumors, psychiatric disorders, and other relatively rare or undefined conditions.

Risk factors for early menopause

Premature ovarian failure affects about 1 out of every 1000 women from ages 15 to 29 and about 1 out of every 100 women aged 30 to 39. It can be related to genetic (inherited) factors, to illnesses like autoimmune diseases, thyroid disease, viral infection, hormonal disorders, and eating disorders. The risk of premature ovarian failure risk increases in women who have relatives with the condition.

Women at risk for surgical or treatment-induced menopause are those who are undergoing treatment for cancer or other conditions that require surgical removal of the female organs.

Signs and symptoms of early menopause

The symptoms of premature menopause are those of typical menopause. They can include:

  • Mood swings
  • Vaginal dryness
  • Changes in cognition and memory
  • Hot flashes
  • Diminished desire for sex
  • Sleep disturbances
  • Weight gain
  • Night sweats
  • Vaginal pain during intercourse

Irregular periods usually precede menopause, and can begin years before periods actually cease.
