During menarche and adolescence, abnormal uterine bleeding (AUB) may serve as a crucial indicator of a hidden bleeding disorder. When a young woman is suspected of having a bleeding disorder, the obstetrician-gynecologist should collaborate with a hemostasis specialist to arrange the necessary laboratory testing and determine the best course of action. The Italian Society for the Study of Hemostasis and Thrombosis and the Italian Society of Gynecology and Obstetrics jointly offer recommendations on the diagnosis and treatment of AUB. They also suggest diagnostic and therapeutic pathways to decrease diagnostic delay and improve treatment effectiveness and safety.
