If you take insulin twice a day and your blood sugar is still high, it is recommended that you consult a doctor in time, and under the guidance of the doctor, formulate an individualized diet plan, exercise appropriately, or add oral hypoglycemic drugs, as well as increase the dosage of insulin injections and replace the insulin, and so on. 1. Adjust the diet: adopt diabetic diet as much as possible, avoiding the intake of foods with too much sugar and foods that are easy to be absorbed, such as thin rice and porridge. 2. Adding oral hypoglycemic drugs: Oral hypoglycemic drugs such as acarbose and metformin can be added in combination with insulin hypoglycemic treatment. 3. Increase the amount of insulin injection: Increase the amount of insulin injection according to the blood glucose situation. 4. Changing insulin: You can change the type of insulin to lower blood sugar better. The treatment of hypoglycemia should be under doctor’s guidance, and you should not take drugs or increase the dosage without authorization.
