Hypomenorrhea

Patients with hypomenorrhea have regularly timed menses but an unusually light amount of flow. This is commonly caused by hypogonadotropic hypogonadism in anorexics and athletes. Atrophic endometrium can also occur in the case of Asherman's syndrome (intrauterine adhesions or synechiae), congenital malformations, infection, and intrauterine trauma. Patients on OCPs, Depo-Provera and the progestin-containing IUDs also have atrophic endometrium and often have light menses as do women who have undergone endometrial ablation. Outlet obstruction secondary to cervical stenosis or congenital abnormalities can also result in hypomenorrhea.
