Gestational diabetes is easy to occur after pregnancy. If the blood sugar is high, it is necessary to control the staple food, eat leafy vegetables instead of some staple foods, do more activities and not eat sweets. You can go to the hospital a week later to check your blood sugar and see if it returns to normal. If it continues to increase, it is necessary to use hypoglycemic drugs in time. Keep a happy mood, exercise more, avoid the blood sugar rising caused by mood swings, and go to the hospital regularly to check the changes of blood sugar.
