Gestational diabetes is defined as impaired glucose tolerance with onset during pregnancy and affects approximately 8.2% of pregnancies. Recently, it has been shown that insulin resistance is a predictor of poor milk supply in women attempting to breastfeed. Some mothers with gestational diabetes who used metformin for optimal glycemic control during pregnancy have found that metformin use has improved their ability to produce milk after delivery; however, the effects of continuing metformin postpartum have not yet been studied. It is theorized that continued metformin use in the postpartum period in women with gestational diabetes may improve postpartum milk production. Using a randomized control trial, our objective is to determine if continuing the use of metformin for 8 weeks postpartum is an effective intervention in increasing milk supply in women who are diagnosed with gestational diabetes. We hypothesize that we will see an increase in breast milk production in these women.
