Gestational diabetes is the most common pregnancy complication. There may not be much you can do to prevent it, but managing diet is key to controlling it.\nWhat Is Gestational Diabetes?\nWhen you\u2019re pregnant, your body needs more insulin than it normally does. When your insulin supply can\u2019t keep up with the new demand, gestational diabetes develops.\nOnly about 7 percent of pregnant moms get gestational diabetes, and there\u2019s usually not much you can do to prevent it. However, some factors can put you at higher risk of developing it.\nGestational diabetes risk factors\n\nA family history of diabetes\nBeing overweight\nHaving had a previous child weight more than 9 pounds at birth\n\nHow Is Gestational Diabetes Diagnosed?\nEarly detection is best to help you keep yourself and your baby healthy. That\u2019s why between 24 and 28 weeks of pregnancy, you\u2019ll have a screening test.\nAfter fasting overnight, you\u2019ll be given a sweet glucose solution to drink. In about an hour, your blood glucose level will be tested. If your level is too high, you\u2019ll be asked to come back for a longer glucose tolerance test, which will determine whether you have the condition or not.\nWhat Complications Can Occur?\nAs long as you manage your diabetes, you\u2019ll likely have a healthy pregnancy and labor. If not controlled, some complications can occur for you and your baby:\n\nHigh blood pressure leading to pre-eclampsia\nPreterm labor\nA large baby with extra fat, which could lead to C-section\nLow blood sugar in the baby right after birth\nMom and baby at higher risk for Type 2 diabetes later in life\n\nHow Can I Manage Gestational Diabetes?\nBy following a few guidelines for diet and exercise, you should be able to stay in control:\n\nWatch carbohydrates \u2014 choose whole grains and limit refined carbs\nEat small meals every few hours\nAvoid extremely sugary foods and drinks, including fruit juice\nAdd a healthy protein to every meal, such as nuts, avocado, lean meat, or eggs\nEat foods high in fiber\n\nAdding in even simple physical activity such as a short daily walk will also help you manage diabetes. In severe cases, insulin may be necessary.\nAlthough your food choices may be a little more limited than you\u2019d like, this is not the time to skip meals. If you don\u2019t eat enough food, your body will still struggle to regulate your blood sugar and you may end up with hypoglycemia, or low blood sugar.\nHypoglycemia symptoms\nSigns of hypoglycemia include:\n\nShakiness\nSweating\nHeadache\nConfusion\nHunger\nSleepiness\n\nIf you have these symptoms, check your blood sugar right away. The easiest way to bring it back up is to eat a small, sweet snack and then your next meal if you can.\nThe symptoms of gestational diabetes go away for most women right after birth. Having diabetes during pregnancy can raise your risk of developing Type 2 diabetes. Continue following healthy habits for eating and exercising to keep your blood sugar in check now and in the future.\nLearn more about gestational diabetes management by visiting the Center for Diabetes and Pregnancy at Magee-Womens Hospital of UPMC.
