The absence or abnormal stoppage of menstruation.
The absence of menstruation in a female of reproductive age.
Cessation of menses. It may be due to the cessation of ovulation as occurs in pregnancy or at the end of the female reproductive period (menopause). It can also be due to inadequate food intake as in anorexia or starvation.
abnormal stoppage or absence of the menstrual flow. It may be caused by congenital abnormality of the reproductive tract or by endocrine (hormonal) dysfunction, malnutrition, marked change in the amount of body fat (as occurs in strenuous exercise programs), severe trauma, or emotional upset. Primary amenorrhea is arbitrarily defined as delay of onset of the menstrual flow (menarche) beyond age 18. Secondary amenorrhea refers to cessation of menstruation in a woman who has previously menstruated. Treatment involves correction of the underlying cause and hormone therapy if necessary. Also called amenia.
The absence of menstruation either in a woman who has never menstruated or in a woman whose regular menstrual cycle has ceased temporarily or permanently.
The absence or stopping of the menstrual periods. It is normal for the periods to be absent before puberty, during pregnancy and milk secretion, and after the end of the reproductive period. In primary amenorrhea the menstrual periods fail to appear at puberty, often because of a congenital defect (e.g. ‘Turner’s syndrome). In secondary amenorrhea the menstrual periods stop after establishment at puberty, for a great variety of reasons including disorders of the hypothalamus (a part of the brain), deficiency of ovarian hormone, pituitary or thyroid gland deficiency, diabetes, mental disturbance, depression, anorexia nervosa, change of surroundings, and removal of the womb or ovaries.
Absence of menstruation; lack of menarche; either primary amenorrhea, failure to menstruate (i.e., lack of menstruation by age 16) or secondary amenorrhea; absence of menstruation for more than 3 months in women who had previously experienced menstruation and who are not pregnant. Amenorrhea may be classed as physiological when it occurs during pregnancy, early lactation, or after menopause or may be caused by medications, e.g., by some forms of hormonal contraception. Pathological, or secondary, amenorrhea is caused by several conditions.
Failure to menstruate at an age when regular menstruation is normal, in the absence of pregnancy or breastfeeding.
The lack of menstrual periods, which can be caused by pregnancy or disruptions in the body that inhibit menstruation.
