Diet is important when a person has gestational diabetes, because it can impact blood glucose levels. If your blood glucose is too high, your body might make ketones, which means it’s using fat for energy instead of glucose, according to the NIDDKD. And if you don’t take steps to manage your glucose, there is an increased risk of still birth, birth trauma, and electrolyte abnormalities in your baby, Dr. Brightman says. Your doctor might ask that you use a blood glucose meter to ensure that you’re staying within your target levels. In some cases, people with gestational diabetes might need to take an oral hypoglycemic medication or get insulin injections to maintain normal glucose levels, she says.
