Clinically, there is no grade 2 diabetes, it should be type 2 diabetes.The severity of type 2 diabetes is mainly related to the patient’s specific condition and whether there are serious complications, etc. If the patient has no other complications, it is not particularly serious. If the patient has no other complications, it is not particularly serious. In general, type 2 diabetes mellitus can be controlled within the ideal range of blood glucose through dietary control, appropriate exercise and hypoglycemic drugs, which can alleviate the patient’s clinical discomfort, improve his/her quality of life, and minimize the occurrence of complications. However, if the patient is accompanied by complications, such as diabetic nephropathy, diabetic foot, diabetic ketoacidosis, etc., such a situation is relatively serious, the patient needs to go to a regular hospital in time, and be given by a professional physician to give symptomatic treatment programs to prevent further aggravation of complications. Whether type 2 diabetes is serious or not should be assessed and judged by a medical professional according to the patient’s actual condition.
