Dysfunctional uterine bleeding as the answer to the question “why won’t my period stop”
The most common etiology of DUB is anovulation, i.e. disturbance of follicle’s maturation and the ovum’s emergence from the latter. As a rule, this happens after the first menstruation and prior to menopause, (in the periods of the endocrine alteration). DUB is mostly treated with hormonal contraceptives, which should be selected by a specialist, with regard to all possible nuances of the disease.
Blood coagulation problems, as one of the causes of prolonged periods
Decreased number of platelets or blood coagulation pathologies (hemophilia) is able to provoke bleeding of various mucous membranes, particularly, prolonged periods, involving a great deal of blood loss. This is not a gynecological pathology. Therefore, its treatment should be trusted to a hematologist.
