Diabetes is a disease diagnosed in Western medicine, based on laboratory tests of blood glucose levels. The counterpart in Chinese medicine is the disease of “thirst”. The meaning of the word “thirst” graphically summarizes the patient’s fluid depletion and physical wasting, and the treatment in Chinese medicine is often centered on these two aspects. The ancients divided thirst into upper, middle and lower extremities, with upper extremities belonging to the lungs, thirsty for more drinks; middle extremities belonging to the stomach, eating and hunger; and lower extremities belonging to the kidneys, urinating like fat, and treatment is mostly based on the evidence of the lungs, stomach and kidneys. However, from the current clinical point of view, due to the increasingly strict laboratory diagnostic criteria, diabetes can be diagnosed at the early stage of onset, and the use of Chinese and Western medicine in most diabetic patients for years, so that most of the clinical patients have atypical or complicated symptoms of the three elimination symptoms, and it is difficult to differentiate and treat with the three elimination symptoms. However, the pathological mechanism of thirst remains in the two points of elimination and thirst. Although most of the early stage of diabetes mellitus is obese, as the disease progresses and the blood sugar is poorly controlled, the depletion of the patient’s form gradually manifests itself. At the same time, most patients will show signs of qi deficiency in Chinese medicine such as mental sleepiness, weakness of limbs, little breath and lazy speech, intolerance of fatigue, and thin and weak pulse. This Qi deficiency is clinically focused on the deficiency of lung, spleen and kidney Qi, which is the theoretical basis for the use of Qi-enhancing drugs in the treatment of diabetes in Chinese medicine. Western medicine treatment focuses on lowering sugar, and most of the attention to the consumption of diabetic physique is not enough. Using Chinese medicine treatment or with Chinese medicine treatment, it can improve the physique condition of patients and improve their internal organs function while lowering sugar. This is also the advantage of Chinese medicine treatment. The pathological basis of thirst lies in the depletion of yin fluid. Due to the early intervention of drugs and changes in the disease spectrum, although significant thirst symptoms are now less common in clinical practice, the depletion of yin is still one of the important pathological bases of thirst. The symptoms of thirst are still clinically evident when blood glucose is elevated or fluctuates. The main treatment for thirst in Chinese medicine is to consume more ingredients and medicines that nourish yin and clear heat, and pharmacological studies have shown that various herbs that clear heat and nourish yin have better hypoglycemic effects. ”The pathology of thirst disorders is the result of a long-standing disease that enters the ligament. The development of multiple complications in the late stage of diabetes is an important hazard of diabetes. The early use of blood-activating drugs can effectively improve and prevent the occurrence of diabetic complications, while blood-activating drugs often play an important role in the clinical treatment of diabetic complications, especially cardiac and cerebral complications. In conclusion, Chinese medicine has an important position in the clinical treatment of diabetes. Chinese medicine has a multi-target and multi-path clinical effect on diabetes, and its treatment alone or in combination with western medicine for hypoglycemia can be more effective in preventing, intervening and treating diabetic patients, improving their constitution and their quality of life.
