Pregnancies often come with a lot of hormonal changes in the human body. These changes can create a wide range of health conditions that weren't there before. Gestational diabetes is among the conditions you may develop when you're expectant. If you've been diagnosed with it, taking appropriate steps to manage the condition is crucial to the health of both yourself and your child. If left unmanaged, gestational diabetes can result in issues such as stillbirth, miscarriages, a larger-than-normal baby and the need for caesarean delivery.
