The treatment of gestational diabetes includes dietary therapy, exercise therapy, and insulin therapy. For dietary therapy, we mainly control the total calorie intake and supplement with elements such as calcium, iron, folic acid, and various vitamins; in exercise therapy, we aim to control the speed of weight gain, improve the peripheral tissues' utilization of glucose, and improve the lipid profile. For patients whose blood glucose levels do not meet the standards after two weeks of diet and exercise therapy, we initiate insulin therapy. The goal of insulin therapy is to control fasting blood glucose below 5.3 and postprandial blood glucose below 6.7. The methods of insulin therapy include twice daily injections, multiple daily injections, or the use of an insulin pump.
