Oligomenorrhea (also oligomenorrhea, from the Greek oligos "little", menos "month", rhoe "flow") denotes a too rare menstrual bleeding . Oligomenorrhea is used when the overall cycle is extended to over 35 days to a maximum of 90 days. The severity of the bleeding and its duration are mostly normal or only slightly reduced. Affected women almost always had normal bleeding cycles before the onset of oligomenorrhea. At the beginning of puberty ( menarche ), oligomenorrhea can also be an expression of normal development, before the hormonal rhythms become regular.
causes
Oligomenorrhea is a symptom of polycystic ovaries caused by an increase in androgens (male sex hormones) in the blood. Hormone secreting tumors can also lengthen menstrual cycles. Much more often, however, oligomenorrhea is a functional disorder as an expression of high physical or emotional stress, prolonged malnutrition (also with anorexia nervosa ), severe chronic diseases with emaciation ( cachexia ). High-performance training can also lead to oligomenorrhea in competitive athletes.
Symptoms
Apart from the extension of the cycle, there are usually no other symptoms.
therapy
The treatment depends on the underlying causes in each individual case.
