Postpartum Glucose Tolerance in Women With Recent Gestational Diabetes Using the Levonorgestrel IUD and Non-Hormonal Contraception: A Prospective Cohort Study
The study is being done in order to gain information on the most suitable types of birth
control in women who recently had gestational diabetes, or diabetes diagnosed during
pregnancy. The intrauterine device (IUD) is a highly effective form of birth control. It is
inserted into the uterus and prevents pregnancy for either 5 or 10 years, depending on the
type of IUD (hormone-releasing or copper). The hormone-releasing IUD works for 5 years and
releases a hormone called a progestin into the uterus. The copper IUD contains no hormones
and works for 10 years. The IUD is an excellent form of birth control postpartum, but it is
unknown if the hormone-releasing IUD will affect blood sugars and increase a woman's risk of
becoming diabetic when she's not pregnant. The hypothesis is that the hormone-containing IUD
will NOT increase blood sugars, so women who use the hormone-containing IUD will have
similar blood sugars to those who use the copper IUD or have had their tubes tied (no
hormones).
