This document discusses gestational diabetes, including its causes, risk factors, diagnosis, treatment, complications, and prevention. Gestational diabetes is a form of diabetes that develops during pregnancy. It occurs when pregnancy hormones interfere with the body's ability to produce and use insulin, resulting in high blood sugar levels. Risk factors include obesity, family history, previous gestational diabetes or large baby, and age over 30. It is diagnosed through glucose tolerance tests. Treatment involves diet, exercise, blood sugar monitoring, and possibly insulin. Complications can affect both mother and baby's health. Maintaining a healthy lifestyle before and during pregnancy can help prevent gestational diabetes.
