title: Plasma glucose and insulin levels in women using a levonorgestrel-containing triphasic oral contraceptive for three months.
abstract: Plasma glucose and insulin levels were measured for three hours after an oral glucose challenge in twenty-nine women before and after using a triphasic oral contraceptive containing ethinyl estradiol and levonorgestrel for three months. There were significant elevations in the glucose levels during the three-month tolerance test, while the insulin levels were unchanged. These data suggest that this OC can alter carbohydrate metabolism and that long-term studies are needed to assess the extent of this metabolic change.
