[Diabetes and oral contraceptives].

20-30 million women use oral contraceptives. The estrogen component, either ethinyl estradiol or mestranol, inhibits the release of the ovum and affects the cervical secretions, the endometrium, the ovaries, and the Fallopian tubes. The gestagen component is derived from 19-nortestosterone or 17-hydroxyprogesterone, and the metabolism of the gestagen component is not fully known. Disposition to thrombosis, liver illness, diabetes, hypertension, amenorrhea, oligo menorrhea, or tumorous changes in the uterus or breasts should not use oral contraceptives. Menstrual disturbances and endometriosis can be controlled by the use of oral contraceptives. Urine samples, blood pressure, and weight should be monitored during oral contraceptive use.
