Metabolic correction surgery (formerly called gastric diversion surgery) to treat diabetes is no longer a rare thing, but there are still many people who are skeptical about the effectiveness of this surgery. It doesn’t matter if you are skeptical, so let’s take a closer look at the principles of surgical sugar reduction, and I’m sure you’ll choose to believe it after reading it. Before talking about the principle, let’s talk about the relationship between obesity and diabetes. Obesity leads to diabetes, at the earliest because there is more lipid accumulation in the cells, so that the sensitivity of the cell surface to insulin is affected, the efficiency of insulin to break down blood sugar is reduced, and the glucose level in the blood will rise. After that, the body finds that the blood sugar is high, it will in turn regulate the secretion of more insulin, and it will lead to the excess insulin level in the blood, forming hyperinsulinemia. We can tell you that hyperinsulinemia is one of the causes of diabetes, and if not treated as soon as possible, the pancreatic islet cells will be irreversibly damaged due to overwork, and insulin secretion will be absolutely insufficient at a later stage, making it difficult to control blood sugar. Then we can talk about surgery, which is actually to change the physiological pathway of food flow through the intestine and stomach through intestinal anastomosis and gastrointestinal anastomosis, to correct the metabolic abnormalities and disorders in the body, to eliminate insulin resistance and improve insulin sensitivity, so as to achieve the purpose of getting rid of taking medicine and insulin blood sugar will still be normal. But as said above, the patient’s state insulin function is gradually damaged, and the surgery must be done before the complete loss of secretory function, and the pancreatic function check C peptide in more than half can be done, if the insulin function is damaged too much, insulin is still not enough after doing the surgery, and it may still need to take medicine for regulation. Therefore, if people are first diagnosed and young obese type 2 diabetes patients, it is recommended to receive surgery early, and surgery is better than conventional medical treatment if considered in the long term. And this is an unavailable opportunity, with changes in their own physical conditions, just because they can do it now does not mean they can do it later, when they will lose this opportunity.
