I often come across patients who say, “Doctor, if I take insulin, can I stop controlling my diet?” . In fact, this is a wrong understanding of diabetes and diabetes diet, the basis of diabetes treatment is diet therapy, so whether oral hypoglycemic drugs or insulin injections, should adhere to the diabetic diet. In the implementation of the diabetic diet should pay attention to the following points: 1, strict “timed, quantitative, fixed meals” insulin injections need to determine the time to eat put, so that the meal time needs to be relatively fixed, so as not to delay the role of insulin, or to avoid hypoglycemic reactions caused by the strongest role of insulin when not eaten. 2.Less food and more meals The insulin supplemented outside the body is directly injected into the body, and it will not decrease due to the drop of blood sugar, nor will it increase due to the rise of blood sugar, while regulating blood sugar with less food and more meals can avoid blood sugar being too high or too low. The general diet arrangement can be made according to three meals in the morning, afternoon and evening. However, some patients are easy to be hungry or have low blood sugar, and they cannot eat too much at one regular meal, so they can arrange 1-2 extra meals in the middle of two meals or before going to bed. It is advisable to choose snacks rich in complex carbohydrates for extra meals. 3.Balanced diet Through a balanced diet, patients can achieve their own nutritional requirements and prevent complications. 4. Carry snacks with you Insulin injections are prone to hypoglycemia, so carry some sweets with you when you go out, such as fruit candies, milk candies, chocolates, cookies, pastries and so on. Eat when hypoglycemic reactions such as heartburn and hunger occur. Xylitol, stevia and other sweeteners or sugar substitutes are not useful for relieving hypoglycemic reactions. 5.Eating before exercise Patients who inject insulin should follow the order of eating snacks→exercise→insulin injection→eating to prevent accidents. When you first start to participate in sports, the dose of insulin needs to be reduced in an appropriate amount.
