Gestational diabetes after diet control and exercise, blood sugar control is still not up to standard, it is recommended that insulin treatment, specific insulin currently applied for human insulin and recombinant insulin, insulin analogues of three, specifically including short-acting Novolin R, or menthol insulin; long-acting insulin is glargine insulin. The specific insulin usage should be determined according to the patient’s blood glucose, for example, if the blood glucose is generally high and high fasting blood glucose is the main reason, you can use long-acting glargine insulin and inject it subcutaneously before bed to control fasting blood glucose; if the patient’s postprandial blood glucose is mainly elevated, you can use short-acting or fast-acting insulin, such as Novolin R, or menthol insulin to control postprandial blood glucose. Of course, for patients with high fasting blood sugar and postprandial blood sugar, they can use glargine insulin combined with preprandial menthol insulin to control blood sugar.
