By far the leading cause of type 2 diabetes is obesity. Many people are not moved by the diagnosis of diabetes and continue to do as they please. The most frightening thing about diabetes is that it can also lead to various complications. The cruel reality is that most people with diabetes are not aware that they have type 2 diabetes, and by the time they are diagnosed, they have already had the disease for quite some time. Is there an age requirement for weight loss surgery that can treat diabetes? The answer is yes. According to the international criteria for the indication of diabetes surgery, one of the requirements is that the age of type 2 diabetes is ≤ 15 years. Of course, in general diabetic patients do not get diagnosed with type 2 diabetes until they are 15 years old. After all, you can wait for diabetes, but the complications of diabetes don’t wait for you. Although the initial symptoms of diabetes are not obvious and do not cause much impact on a person’s daily life. However, after a few years, as the disease worsens, the body develops complications such as retinopathy, fatty liver, diabetic bone and joint disease, myocardial infarction, diabetic foot ulcers and gangrene, and more than a dozen other complications involving the entire system of the body. Therefore, if type 2 diabetes is caused by severe obesity, it is best to consider weight loss surgery as a treatment option. Because with conventional medical treatment, diabetes can only be suppressed by lifelong medication, and the physical problems cannot be solved.
