To date, according to statistics, the number of people with diabetes worldwide is approaching 400 million, and 4.9 million people die from diabetes each year, which is equivalent to one death every seven seconds. It is said that half of the people with diabetes do not know they have the disease. As we all know, diabetes is getting younger and younger and more and more people are suffering from the disease. In China, the prevalence of diabetes has nearly tripled in the last 10 years, making it the world’s number one diabetic country. The above data shows that diabetes is no longer a “benefit” for the rich and powerful. We should pay attention to the problem of diabetes. The factors that cause type 2 diabetes: 1, the diet structure is unreasonable Nowadays, the standard of living can be said to be higher and higher, but many people’s diet structure is getting unhealthy. The meal fine rice and white noodles, ton of big fish and meat, too much meat, eggs and milk, too little coarse grains and vegetables, high calorie, high fat, high protein diet to make the diabetes team unprecedented growth. 2, unhealthy lifestyle Unhealthy lifestyle is very common in our life, and this is very easy to cause diabetes to occur. People’s health care knowledge lags behind, meals fat, sweet and thick taste, go out to the car, coupled with excessive calorie intake, serious lack of exercise, as well as the fast pace of life, work pressure, increased psychological stress, these factors can induce or aggravate diabetes. 3, obesity The body of people who are too obese are prone to a variety of diseases, and diabetes is also one of the common. The total amount of fat in the body of obese people increases, and the number of insulin receptors on the surface of fat cells decreases, making it less sensitive to insulin, and eventually diabetes occurs. According to the survey, 60% to 90% of adult diabetic patients belong to obese body type. Surgery for type 2 diabetes: Gastric diversion surgery treatment is a good choice for obese type 2 diabetes patients, which can remove insulin resistance, cure diabetes, free patients from lifelong medication, and also help patients lose weight, with outstanding results in one stroke. Gastric diversion surgery intervenes in the metabolism of sugar and fat by changing the flow path of food in the gastrointestinal tract, increasing insulin sensitivity and reducing insulin resistance, promoting the proliferation of pancreatic beta cells, improving the function of the pancreas, and correcting the disordered glucose metabolism to cure diabetes. Two mechanisms of gastrointestinal diversion surgery to lower blood glucose: The first is the restorative effect of islet function; reconstruction of islet repair of gastrointestinal hormones, the provincial role of gastrointestinal hormones is to regulate islet function, and there is gastrointestinal hormone regulation of insulin dysfunction in diabetic patients. After surgery, food still passes through the distal small intestine, and the hormones secreted here from the small intestine have a hypoglycemic effect, such as glucagon-like state-1. While there is no food passing through the distal stomach, duodenum and proximal small intestine, the hormones secreted here have an elevating effect on blood glucose. The second is the load-shedding effect of the islets; that is, the heavier the body is, the more capacity it needs, and the more insulin it naturally requires. The reason: glucose is the main energy supply substance in the body, and the role of insulin is to promote the uptake and utilization of glucose. Therefore, the process of releasing energy from glucose is inevitably inseparable from insulin. When the absorption of sugar is artificially controlled, the amount of insulin required by the body is also reduced, and the contradiction between the supply and demand of insulin is relieved, which helps to control the blood sugar level. Advantages of surgical treatment: Advantage 1: Cure diabetes, normal blood sugar, patients get rid of lifelong medication and do not need to control diet. There are two main reasons for the development of diabetes: one is insulin resistance. The second is pancreatic islet failure. After gastric diversion surgery, insulin resistance is gone, islet function is restored, and diabetes is gone. Advantage 2: Diabetic complications are recovered. While internal medicine cannot reverse the complications that have occurred in patients, after gastric diversion surgery, most patients gradually recover from diabetic complications such as numbness in hands and feet, retinopathy, diabetic foot, abnormal urine protein, and hypertension. Advantage 3: Avoid the occurrence of disabling and fatal conditions caused by diabetes. When diabetes develops to a serious level, it can pose a serious threat to a person’s life safety. After gastric diversion surgery, blood sugar is normal, complications no longer occur, and the danger of diabetes is gone. Advantage 4: Weight loss in obese patients and weight gain in thinner patients. Gastric diversion surgery can bring some unexpected effects to patients, very thin patients will gain weight after surgery, and very fat patients achieve satisfactory weight loss after surgery. Advantage 5: Reduce the financial burden of the patient. The relative cost is not high, which is the obvious advantage of gastric diversion surgery. According to the survey, most diabetic patients who have been ill for more than 5 years will develop various complications, and the cost of treating these complications is very high. For diabetic patients, a single surgical treatment, complications no longer appear and the financial burden is reduced. Advantage 6: Gastric diversion surgery has low risk and fast recovery after surgery. The surgery is easy and quick, with little trauma, quick recovery and no recurrence, and you can eat in 3 days after the surgery and be discharged in a week. Post-operative diet and nutrition absorption are basically unaffected.
