There are many people with diabetes who are concerned about when they can get pregnant, what they should do to prepare for pregnancy, and how to adjust their medications for diabetes. The following is only a brief introduction. I. General preparation It applies to all women who are ready to get pregnant, such as staying away from toxic and harmful chemicals, avoiding overwork, keeping a happy mood, eating more fruits and vegetables, refusing junk food, etc. Diabetic patients should go to the hospital for a comprehensive examination before pregnancy to clarify whether there are complications of diabetes and whether it is safe to get pregnant. Second, the diabetic patient’s blood glucose preparation During pregnancy, the diabetic patient’s blood glucose requirements are more strict, because only more strict control of blood glucose can reduce the occurrence of maternal and fetal complications. The specific requirements are: fasting blood sugar between 3.3-5.6 mmol/L, 5.6-7.1 mmol/L 2 hours after meals, and glycosylated hemoglobin <6%. Since pregnancy itself can make blood glucose difficult to control, it is traditionally believed that if a pregnant woman's blood glucose does not reach the standard after dietary and exercise adjustments, insulin may be considered to be started for the benefit of mother and child. New studies have shown that several oral hypoglycemic agents can also be used during pregnancy, such as gliphenylurea, a drug that promotes insulin secretion and cannot reach the baby through the placenta, so it can also be used safely during pregnancy. Another class of oral medication, metformin, can reach the fetus, but no teratogenic effects have been found. Patients can discuss with their doctors to decide whether to continue taking the drug during pregnancy. If the patient is taking oral antihypertensive drugs with chemical names ending in "Satan" or "Priligy", he/she should consult his/her doctor and change the antihypertensive drug to avoid adverse effects on the fetus. If the patient is taking oral antihypertensive drugs with chemical names ending in "Sartan" or "Pulley", he/she should consult the doctor and change the antihypertensive drugs to avoid adverse effects on the fetus. Exercise is essential for diabetic patients whether they are pregnant or not. Exercise can increase insulin sensitivity, reduce the dose of oral medication or insulin, and improve blood sugar control. Exercise time: 30 minutes after meals Exercise mode: low→moderate intensity aerobic exercise - walking is the easiest Exercise time: 10 to 30 minutes Exercise frequency: 3-4 times/week Exercise precautions: You need to consult your doctor before exercising to ensure safe exercise. Carry sugar cubes, cookies, snacks, etc. during exercise, and eat promptly if symptoms of hypoglycemia occur. V. Preparation of dietary habits Diabetic patients' diet is more difficult to control during pregnancy, both to provide adequate nutrition for fetal growth and to avoid high blood sugar. It is recommended that all patients consult a dietitian to develop a reasonable diet plan. This will be described later.
