Diabetes mellitus is a metabolic disease characterized by hyperglycemia, which is called achalasia in Chinese medicine and is now collectively referred to as diabetes mellitus, and is divided into type 1 diabetes, type 2 diabetes, gestational diabetes, and other special types of diabetes. Diabetes is associated with genetic factors, environmental factors, and inappropriate lifestyles, such as diet. Diabetes can be diagnosed if there are symptoms such as thirst, excessive drinking, polyuria, weight loss, and fasting blood glucose ≥ 7.0 mmol/L or 2 hours postprandial blood glucose ≥ 11.1 mmol/L, or random blood glucose ≥ 11.1 mmol/L. If there are no these obvious symptoms, the blood glucose needs to be retested, and if it exceeds this value, diabetes can also be diagnosed.
