meno-
Prefix meaning pertaining to the menses.
menometrorrhagia
Excessive uterine bleeding,
both at the usual time of menstrual periods and at
other irregular intervals. Menometrorrhagia can be
a sign of a number of different disorders, including
hormone imbalance, endometriosis, benign fibroid
tumors in the uterus, and cancer. Anemia may result
from the excessive uterine bleeding. Treatment
depends on the cause: If there does not appear to be
a dangerous cause, such as cancer, then hormone
supplementation or the therapeutic use of birth
control pills to better control the menstrual cycle
may be recommended. See also 
menorrhagia;
metrorrhagia.
menopause
The time for a woman, usually in
middle age, when menstrual periods end.
Menopause is defined as the absence of menstrual
periods for 12 consecutive months. Natural
menopause occurs when the ovaries begin decreas-
ing their production of the sex hormones estrogen
and progesterone, and the timing of menopause
varies, with an average age of 51 in the Western
world. Changes associated with approaching
menopause may include night sweats, mood swings,
vaginal dryness, fluctuations in sexual desire
(libido), forgetfulness, trouble sleeping, and fatigue
(probably due to the loss of sleep). Hormone ther-
apy (HT) is sometimes prescribed to relieve the
symptoms of menopause. Also known as change of
life. See also 
estrogen replacement therapy; hor-
mone replacement therapy; menopause transi-
tion; menopause, induced.
menopause, chemical
Menopause that is
induced by chemotherapy or by other chemicals or
medications. See also 
menopause; menopause,
induced.
menopause, induced
Menopause that is caused
by surgical removal of the ovaries, or grave damage
to the ovaries by radiation, chemotherapy, or med-
ication. Because of the abrupt cutoff of ovarian hor-
mones, induced menopause may cause the sudden
onset of hot flashes and other menopause-related
symptoms, such as vaginal dryness and a decline in
sex drive. See also 
menopause; menopause,
chemical.
