Unstable blood glucose may be caused by dietary factors, irregular medication, stressful blood glucose elevation, and hyperthyroidism, gastrojejunostomy.
1. Dietary factors: Irregular diet, not regular, quantitative food or suddenly eating food with high sugar content will cause large fluctuations in blood sugar.
2. Irregular use of medication: diabetic patients adjust the dosage of insulin or oral hypoglycemic drugs on their own can cause unstable blood sugar.
3. Stress blood glucose increase: the body is stimulated by trauma, infection and other stress factors can cause a sudden increase in blood glucose, and then return to normal.
4. Hyperthyroidism or gastrojejunostomy: Due to the fast basal metabolic rate of hyperthyroidism or the structural reasons after gastrojejunostomy, the carbohydrates are absorbed too fast in the intestines, which leads to the high blood glucose half an hour to one hour after meal, but the blood glucose two hours after meal and fasting blood glucose are normal, and the blood glucose instability can also occur in such cases.
In such cases, unstable blood glucose can also occur. You can go to the hospital and ask your doctor to make a judgment.
