The best way to restore the function of pancreatic islets is to maintain the blood glucose standard and stability for a long period of time, commonly used methods include diet, exercise, weight control, drug therapy, etc. 1. Diet: Excessive sugar and fat in the body will form “glycotoxicity” and “lipotoxicity”, which will directly damage pancreatic islet cells. Reducing the intake of sugar and lipids, combining with low carbon, low fat, high protein and high fiber diet, and controlling the total calorie intake every day can gradually reduce the blood glucose level and improve the internal environment of pancreatic islets. 2. Exercise: Exercise can lower blood sugar and reduce the damage of high blood sugar to pancreatic islets. Exercise helps to control body weight and can increase muscle content, which is conducive to blood glucose control, improve insulin resistance and facilitate the recovery of pancreatic islet function. 3. Weight control:In overweight or obese patients, there is too much fat in the body, which will accumulate in the liver and pancreatic tissues, and it is also easy to cause damage to pancreatic β-cell function. Through reasonable weight reduction, it can reduce the fat in internal organs, liver and pancreatic β-cells. With less fat, organs and cells work hard, which can effectively improve insulin resistance and control blood sugar. 4. Drugs: Oral hypoglycemic drugs can be used to treat high blood sugar, such as metformin hydrochloride extended-release tablets, glimepiride tablets, etc., which need to be taken under the guidance of a doctor. If the blood sugar is too high, insulin injection can be considered. Whether you take medication or inject insulin therapy, keeping your blood sugar at the desired level will protect the remaining pancreatic islet function. The best way to restore pancreatic islet function is to manage blood glucose, monitor blood glucose regularly, visit your doctor regularly, and take treatment under the guidance of a specialist.
