BNORMAL uterine bleeding is ascribed to a functional origin when A the pelvic organs are normal and when no constitutional disease or blood dyscrasia exists to account for it. The modern conception of its etiology recognizes an alteration from the normal functional relationship between the hypophysis, the thyroid, the ovaries and the endometrium. Functional bleeding occurs most commonly during the fifth decade of life, but it is encountered frequently in women of less mature years in whom preservation of the menstrual and procreative functions is of vital importance. In many of the milder forms, the blood loss is insufficient to require treatment, as is often the case in adolescence. The same may occur during the menopausal age, but here the more likely cause of irregular bleeding is a myoma or cancer and hopeful expectancy is warranted only when the possibility of these organic lesions has been eliminated. The wide age distribution of functional bleeding necessitates a variation in the objectives of its treatment. If we could devise an ideal therapeutic method, it would have for its result preservation of the normal menstrual and procreative functions in women under forty, and the return to normal periods or amenorrhea without severe menopausal symptoms in women beyond this age. Unfortunately, the methods at our disposal often fall short of this ideal, but in our choice of treatment, we should attempt to approach it as nearly as possible. Only too often methods are employed with the control of bleeding as the only objective and with entire disregard of the disastrous sequelae which may accompany the destruction of ovarian or reproductive function. Proof that the ideal treatment of functional bleeding has not been found is the large number of therapeutic procedures which have been and are still being introduced. These methods may be divided into seven groups: (1) Hygienic measures. (2) Uterine stimulants. (3) Means to increase the coagulability of the blood or to decrease the permeability of the capillaries. (4) Endocrine therapy. (5) Removal or ,destruction of the endometrium. (6) Roentgen or radium therapy. (‘7) Surgical procedures upon the ovaries or the uterus. Hygienic measures are of value when used in conjunction with appropriate medical and glandular therapy. Constitutional defects often
