Diabetic patients can get married. Diabetic patients with early blood sugar control up to standard, blood pressure, lipid and weight control up to standard can reduce the incidence of chronic complications of diabetes, and have no impact on patients’ study, work and life expectancy, so they can get married. After marriage, diabetic patients need standardized glucose-lowering treatment, regular monitoring of blood glucose, fundus and urine microalbumin, lipids and other indicators to make the condition control stable. If there is no chronic complications such as diabetic retinopathy and diabetic nephropathy, with good glycemic control, glycosylated hemoglobin control below 6.5% can be normal pregnancy and childbirth, and there is no impact on the patient’s life, the key is to achieve the standard of glycemic control and stable disease control.
