title: [Menstrual disorders in adolescents: commonplace or worrisome?].
abstract: The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.
