Gestational diabetes refers to the onset of diabetes during pregnancy, or the first detection of varying degrees of hyperglycemia, including glucose intolerance and diabetes that were not identified before pregnancy. The risks of gestational diabetes are more severe in patients with serious conditions or poor blood sugar control, as it can easily lead to miscarriage and preterm birth, infections, and in severe cases, ketoacidosis. So, how can gestational diabetes be controlled? It can be managed through dietary control and insulin treatment. Dietary control is crucial; the ideal dietary management aims to ensure and meet the caloric and nutritional needs during pregnancy while preventing hyperglycemia or ketosis due to starvation, ensuring normal fetal growth and development. For cases where dietary management is insufficient to control diabetes, insulin is the primary medication. (Please seek professional medical guidance before using any medication, and do not self-medicate.)
