Significance of low body weight in ovulatory dysfunction after stopping oral contraceptives

In a group of patients who developed ovulatory dysfunction on stopping oral contraception the mean body weight of those with previosly regular cycles was significantly lower than that of women who had had ovulatory dysfunction beforeoral contraception and also that of a control group. Women of low body weight may be at particular risk of developing post-pill amenorrhoea even when there is no history pointing to ovulatory dysfunction. This should be considered when selecting a form of contraception in such women.
