During pregnancy, if the pregnant woman has diabetes, it is essential to control blood sugar reasonably. Otherwise, high blood sugar can seriously affect both the fetus and the pregnant woman, and in severe cases, it can cause diabetic ketoacidosis in the pregnant woman and fetal death in utero. Diabetes in pregnant women can be intervened in the following ways: First, through dietary control, eat less sugary foods, such as sweets, pastries, and fruits. Second, it is necessary to be moderately active during pregnancy, taking a walk or maintaining 5,000 to 10,000 steps daily, which helps in the consumption of glucose in the body. Third, if the above two methods are ineffective, insulin should be used to control diabetes.
