Gestational diabetes can drink mung bean soup, but no sugar can be put in it, otherwise it will easily cause an increase in blood sugar or abnormal blood sugar. Mung bean soup has the effect of clearing heat and detoxifying the body, but you should not drink too much of it. Drinking too much of it can easily cause stomach cold and harm the gastrointestinal tract, causing gastrointestinal tract dysfunction, which may cause stomach pain or gastrointestinal discomfort. If you have diabetes during pregnancy, it is best to control your diet, eat more fresh vegetables, fruits, foods with low sugar content, and try to eat less sugary or greasy foods. In addition, you should also strengthen your exercise, and moderate exercise is good for sugar control. If the blood sugar is not well controlled, unstable or persistently elevated, it is best to treat with insulin under the guidance of a doctor, because pregnant women are not allowed to take oral hypoglycemic drugs.
