When low blood sugar occurs, we must first find the cause of low blood sugar, and only for the cause can we make the correct adjustment. The main adjustment methods are: 1. If the low blood glucose is caused by irregular diet, we should develop a reasonable diet structure and healthy diet, and avoid late night snacking and overeating. 2. For emotional and stressful conditions that may lead to blood glucose fluctuation, such as excitement, agitation, sadness, grief, cold, heat, stress, trauma, infection, surgery, etc., the triggering factors should be removed as soon as possible. 3. Patients with type 1 diabetes should monitor blood glucose more closely and adjust insulin dosage according to blood glucose and diet in time to avoid hypoglycemia and rebound hyperglycemia after hypoglycemia. 5. Hypoglycemia and fluctuation of blood sugar. When unavoidable triggers lead to low blood sugar, timely treatment should be taken to correct hypoglycemia to prevent the occurrence of severe hypoglycemia, while actively finding the cause of low blood sugar and making adjustments to prevent the recurrence of hypoglycemia.
