Functional Uterine Bleeding

Functional uterine bleeding is deisgnated as irregular uterine bleeding occuring the child-bearing age of a woman in the absence of any detectable pelvic pathology.Hyperplasia of the endometrium is the most important single cause of functional uterine bleeding. Therefore, functional bleeding and metropathia haemorrhagica previously are synonymously used, but it is not so, at present, because the bleeding occures not only from cystic-hyperplastic endometrium but also from atrophic, normally proliferative, and secretory endometrium.The ultimate cause is unknown. But the normal control of menstual function is disordered as a result of disturbance in anterior pituitary function, ovarian reactivity to pituitary stimulation and endometrial sensitivity to ovarian hormones. In most cases, probably, the anterior pituitary gland is primarily disordered.
