Sugar man generally refers to a person with diabetes who needs to be treated aggressively under the guidance of a medical professional to improve his or her prognosis. Diabetes mellitus is a common chronic metabolic disease. Abnormally elevated blood glucose levels due to reduced insulin secretion or impaired utilization are the most prominent manifestation of the disease. Under the action of long-term high blood glucose level, it may cause damage to the patient’s heart, liver, kidneys, brain cells, optic nerves, blood vessels and other systemic organs and functions of the whole body, and in serious cases, it may lead to the death of the patient, which requires timely treatment. There is no cure for diabetes. For diabetic patients, the main treatment modalities are health education, diet, medication, proper exercise, and blood glucose monitoring, which are also known as the five carriages of diabetes treatment, which can slow down the progression of the disease. Diabetic patients who have been actively treated under the guidance of a professional physician and whose blood glucose levels are well controlled generally have a later onset of diabetic complications, a lower morbidity rate, and a better prognosis.
