Polymenorrhea (synonyms: Bleeding abnormality – (interval < 25 days); Bleeding abnormality – polymenorrhea (interval < 25 days); Menstrual bleeding (interval < 25 days); Polymenorrhea; Polymenorrhea; Cycle disorder – polymenorrhea (interval < 25 days); ICD-10 N92.0: Menstruation too heavy or too frequent with regular menstrual cycle: polymenorrhea) is a rhythm disorder. The interval between bleeding is less than 25 days, so bleeding occurs too often. Bleeding abnormalities (bleeding or menstrual cycle disorders) are divided into rhythm disorders and type disorders.
The rhythm disorders include:
- Polymenorrhea – the interval between bleeding is < 25 days, i.e., bleeding occurs too often
- Oligomenorrhea – the interval between bleeding is > 35 days and ≤ 90 days, i.e. bleeding occurs too infrequently
- Amenorrhea – no menstrual bleeding until the age of 15 (primary amenorrhea) or no menstrual bleeding for > 90 days (secondary amenorrhea)
In polymenorrhea, there is usually an ovarian dysfunction (ovarian dysfunction), which is often hypothalamic-dysfunctional. The hypothalamus is part of the diencephalon (interbrain) and serves as the supreme regulatory center for all endocrine and autonomic processes.
Frequency peak: the maximum occurrence of polymenorrhea is after menarche (first menstrual period) and before the climacteric (female menopause), since endocrinological (hormonal) changes take place in the body at both times.Polymenorrhea may also occur postpartum (i.e. after childbirth).
Course and prognosis: If polymenorrhea persists for more than two years after menarche (time of the first menstrual period), these cycle disorders must be clarified. The therapy is cause-related. If stress is the trigger for polymenorrhea or other psychological stress, pharmacotherapy (drug therapy) is usually not necessary – the cycle returns to normal on its own when the triggering factors cease to exist.
