Patients with high blood glucose should go to the hospital for a review of their blood glucose levels to rule out transient elevation of blood glucose caused by various factors, or to clarify whether there is impaired glucose tolerance, diabetes, etc. Patients with confirmed diabetes need to cooperate with their physicians for glucose-lowering treatment in a timely manner. It is recommended that patients with high blood glucose go to the endocrinology department of regular hospitals for detailed consultation.
