Type 2 diabetes does not necessarily end up with complications. The specifics are related to their treatment, condition, etc. Type 2 diabetes is an elevation of blood glucose due to insufficient insulin secretion or insulin resistance. Whether or not type 2 diabetes will develop complications is related to the control of the patient’s condition. When patients are detected early, treated early, have good glycemic control, control cardiovascular factors, and have good lifestyle habits, patients may not develop complications. When patients with type 2 diabetes are treated late, have poor glycemic control, and poor control of cardiovascular factors, the patient’s blood glucose level is high, which can lead to complications such as diabetic nephropathy and diabetic foot. Type 2 diabetes should go to the hospital in time for further examination and treatment under the guidance of professional doctors.
