  • Title: Effect of oral contraceptives on plasma glucose, insulin, and glucagon levels.
    Author: Gossain VV, Sherma NK, Michelakis AM, Rovner DR.
    Journal: Am J Obstet Gynecol; 1983 Nov 15; 147(6):618-23. PubMed ID: 6356926.
    Abstract:
    Effects of oral contraceptive agents (mestranol and norethindrone) on carbohydrate metabolism were evaluated in a group of 18 healthy young women. Plasma glucose, insulin, and glucagon responses were evaluated after a glucose load (oral and intravenous) and an amino acid challenge (oral and intravenous). The oral glucose tolerance was normal and was unaltered by the use of oral contraceptive agents. However, following intravenous administration of glucose, plasma glucose levels were slightly but significantly elevated when subjects were using oral contraceptives. Plasma insulin concentrations were slightly but significantly higher than control values in response to oral and intravenous administration of glucose while subjects were using oral contraceptives. Plasma glucagon concentrations in response to oral and intravenous glucose were similar whether the subjects were using oral contraceptive agents or not. No significant differences from control values were observed after oral and intravenous amino acid challenges when subjects were using oral contraceptive agents. Mild elevations of glucose and insulin without any significant change in glucagon concentrations suggest that glucagon levels do not play a major role in the development of insulin resistance seen in some patients using oral contraceptive agents. Effects of oral contraceptive (OCs; mestranol and norethindrone) on carbohydrate methabolism were evaluated in a group of 18 healthy young women. Plama glucose, insulin, and glucagon responses were evaluated after a glucose load (oral and intravenous) and an amino acid challenge (oral and intravenous). The oral glucose tolerance was normal and was unaltered by the use of OCs. However, following intravenous administration of glucose, plasma glucose levels were slightly but significantly elevated when subjects were using OCs. Plasma insulin concentrations were slightly but significantly higher than control values in response to oral and intravenous glucose administration while subjects were using OCs. Plasma glucagon concentrations in response to oral and intravenous glucose were similar whether the subjects were using OCs or not. No significant differences from control values were observed after intravenous and oral amino acid challenges when subjects were using OCs. Mild elevations of glucose and insulin without any significant change in glucagon concentrations suggest that glucagon levels do not play a major role in the development of insulin resistance seen in patients using OCs.
