Postprandial Glucose Handing in Contraceptive and IUD Users

Goals: The long-term use of hormonal birth control has been shown to effect glucose handling, or blood sugar regulation, and potentially lead to insulin resistance which increases a person's risk for metabolic diseases such as type 2 diabetes. The goal of this study is to investigate how the body handles glucose, in three groups of young, healthy females: NAT (naturally cycling, or not using hormonal birth control), OCP (taking a birth control pill), and IUD (using an intrauterine device). Objectives: We will investigate if the body's ability to handle glucose differs between these groups. We will also explore if these differences are linked to the levels of primary sex hormones in females, estrogen and progesterone, and if the synthetic versions produced by hormonal birth control have the same negative effect. We will use an oral glucose tolerance test to investigate these potential differences, having participants drink a 75 gram glucose beverage and taking blood samples every 15-30 minutes for a 2-hour timespan. These blood samples will be used to measure glucose and insulin levels in the blood to determine any changes that occur in the body in response to glucose.
