Gestational diabetes cannot be treated with oral medications, as they can affect the fetus. Currently, the main treatment for gestational diabetes in China is insulin, with options for short-acting or rapid-acting insulin. If fasting blood glucose is high, long-acting insulin can be used to control fasting blood glucose levels. If post-meal blood glucose is high, short-acting or rapid-acting insulin can be used to control post-meal blood glucose levels. The blood glucose control standards for gestational diabetes are fasting blood glucose between 4.0 and 5.3, and two hours post-meal blood glucose between 4.4 and 6.7.
