A girl’s menstruation once every half a month may be due to physiological reasons or pathological reasons, such as dysfunctional uterine bleeding, uterine fibroids and other causes.
1. Physiological reasons: girls who have just started menstruating, the reproductive endocrine axis in the body has not yet been fully established, and the secretion of sex hormones in the body is still unstable, which may lead to the situation that menstruation occurs once every half a month. If this happens occasionally, it can be left untreated for the time being.
2. Dysfunctional uterine bleeding: if a girl often has semi-monthly menstruation and heavy menstruation, it may be caused by anovulatory uterine bleeding.
3. Uterine fibroids: If a girl suffers from uterine submucous fibroids, it may also affect her menstrual cycle, leading to menstruation once every half a month.
There may be other reasons for girls to have menstrual periods once every half a month, so it is recommended to consult a doctor in time, complete the relevant examinations, clarify the causes under the guidance of a professional doctor, and actively target treatment.
