Many patients with stomach problems usually pay special attention to their diet and eat less, so this diet will not lead to an increase in blood sugar or even diabetes. However, patients who do not pay attention to their diet, overeat, eat a lot of sweets, and are relatively obese are prone to diabetes. The onset of diabetes is mainly due to a decrease in the level of insulin secretion by pancreatic beta cells or the presence of insulin resistance, which leads to the occurrence of diabetes, and there is no direct link between itself and stomach disease, which are two completely different diseases. If diabetic patients are treated with diet control and proper exercise, along with appropriate hypoglycemic drugs, blood sugar will be better controlled, but poor long-term control of blood sugar will lead to the occurrence of gastroparesis.
