Type 2 diabetes is also a disease, which is a chronic metabolic disorder. It is usually closely related to genetic background, which is usually reflected in the presence of type 2 diabetes in the family. It is also associated with lifestyle, such as a love of sugary, fatty foods and living in a state of overweight and obesity, which can easily induce metabolic abnormalities that lead to insulin resistance and induce type 2 diabetes. The reason why some people think it is not a disease is because type 2 diabetes usually works well in terms of treatment. Some populations can even achieve the possibility of reversal through dietary interventions combined with exercise and aggressive weight control in the early stages of the disease. But this state of health comes with a caveat, and if lifestyle interventions are poor or medications are not taken on time and in the right amount, serious complications may arise. Without active lifestyle interventions and good weight management, type 2 diabetes can also lead to complications associated with elevated blood sugar. High blood glucose can lead to diabetic ketoacidosis and even to hyperglycemia and hyperosmolarity syndrome. Chronic high blood sugar can cause damage to various organs, including kidney damage, eye damage, and vascular disease. Therefore, although there is no need to worry too much about type 2 diabetes, it is important to pay attention to the condition and control it well.
