Gestational diabetes is a form of high blood sugar that appears during pregnancy and usually resolves after birth. Many people have no obvious symptoms, which is why screening (often a glucose test around the middle of pregnancy) is important. When symptoms do occur they can include increased thirst, frequent urination, tiredness, and a dry mouth, but these overlap with normal pregnancy.
Risk is higher with factors like a higher body weight, a family history of diabetes, certain ethnic backgrounds, previous gestational diabetes, or a previous large baby.
If diagnosed, it is managed with dietary changes, activity, blood sugar monitoring, and sometimes medication, all guided by your care team. Good control lowers risks to you and your baby. Attend recommended screening and follow-up, since untreated high blood sugar can affect the baby's growth and delivery.
