Diabetes is a condition that affects pregnancy. The hyperglycemic state of a pregnant woman during pregnancy can affect the development of the fetus and lead to the occurrence of adverse pregnancy outcomes. It is currently considered possible for a person with diabetes to become pregnant. In order for pregnancy to proceed normally and smoothly and to ensure the health of the fetus, the prerequisite for pregnancy in diabetic patients is that the blood sugar is controlled within normal limits. Therefore, it is recommended that diabetic patients see a local hospital to regulate their blood glucose before preparing for pregnancy. During pregnancy, it is important to regularly test blood sugar changes and pay attention to dietary results as well as nutrition. It is important for diabetics to follow a diabetic diet during pregnancy so as to avoid the effects of diet on blood glucose. If the diet does not control blood glucose well during pregnancy, oral medication or insulin is needed to control blood glucose. Monitoring of blood glucose should be accompanied by regular prenatal checkups to observe fetal development. Finally, due to the effect of diabetes on fetal development, it is recommended to terminate the pregnancy in late pregnancy until 39-40 weeks to avoid neonatal respiratory distress after the birth of the newborn. Therefore, it is possible for a diabetic patient to become pregnant and to monitor changes in blood glucose during pregnancy and to give medication if necessary.
