High glucose tolerance usually indicates elevated blood sugar, but it cannot be diagnosed as diabetes. Weight management should be carried out in time to avoid developing gestational diabetes, which can be harmful to the pregnant woman and the fetus. Generally, you can try to control it by the following methods: 1. control diet: you should control the intake of sweets and fruits with high sugar content, eat more fresh vegetables, eat a light diet, drink some sugar-free soy milk and milk in the morning, and eat some mixed rice and vegetables for lunch and dinner to enhance resistance and avoid symptoms such as anemia and weakness; 2. appropriate exercise: you can take a walk twice a day for 20-30 minutes each time, or do gymnastics for pregnant women. This can effectively alleviate the elevation of blood sugar in the body, but we should pay attention not to exercise on an empty stomach and avoid strenuous exercise; 3, medication: if the control of blood sugar by diet and exercise is not satisfactory, we should consult a doctor in time and use medication to control blood sugar under the guidance of a doctor. If high glucose tolerance is found during pregnancy, it may lead to excessive fetal development, which may easily cause huge babies, and may also trigger hypertonic coma and ketoacidosis in pregnant women, etc. Therefore, attention should be paid to it. Pay attention to regular monitoring of fasting and two-hour post-meal blood glucose. If the blood glucose cannot reach the target value, you should go to the hospital for relevant examination in time and be guided by the doctor for regulation.
