Hypoglycemic tolerance (IGT – fasting blood sugar between 6.1-7.0mmol/L, postprandial blood sugar between 7.8-11.0mmol/L) refers to the intermediate state of glucose metabolism between normal and diabetes, several large national adult diabetes epidemiological surveys in China show that the prevalence of IGT in 1989 The IGT population is the reserve army of diabetic patients, and the huge IGT population indicates that the trend of diabetes mellitus epidemic is still developing, so it must be paid great attention by the society. IGT can have no symptoms and is not considered diabetes, so many people do not take it seriously. However, not only do almost all diabetic patients have to go through the IGT stage, but some of them are at a much higher risk of cardiovascular disease due to long-term insulin resistance or hyperinsulinemia, hyperlipidemia and hypertension. Patients with IGT should first pay attention to the standard of living behavior, try to “control the mouth, move the legs, clear the mind and sleep early”. Western medicine mostly recommends the use of drugs such as Bystolic and Metformin to improve tissue sensitivity to insulin, protect pancreatic B cells and correct abnormalities in glucose tolerance. Diabetes mellitus can be classified as “thirst disorder” or “spleen disease” in Chinese medicine, while hypoglycemia is correspondingly “thirst disorder” or “spleen disease “The hypoglycemia is the pre or early stage of the disease. Su Wen? This person must have eaten a lot of sweet and fatty food. The fatty food makes people hot inside, and the sweet food makes people full in the middle, and the gas overflows upwards, turning into thirst. Both IGT and diabetes mellitus are the result of insufficient relative or absolute secretion of insulin and insulin resistance. From the perspective of Chinese medicine, insulin is the Yin essence of the human body and is the material basis of fluids. Only when fluids (insulin) are sufficient and distributed evenly and run normally, can the body be plump and full of spirit; and when fluids (insulin) are insufficient, it will manifest as dry mouth, thin body, dry skin and other symptoms. Therefore, for patients with IGT who are thin, they should mainly replenish fluid and use the formula for eliminating thirst (the formula contained in “Danxi Xinfa”). It is composed of Huanglian powder, smallpox powder, human milk (or cow’s milk), lotus root juice, raw earth juice, ginger juice, etc., which is contained in the Anti-thirst Pill of Zhongyi Pharmaceutical), Sha Shen Mai Dong Tang (Sha Shen, Mai Dong, Mulberry leaf, Yu Zhu, lentil, smallpox powder, licorice), or agents that benefit Qi and nourish Yin (such as Huang Qi, Bian Jiao Ginseng, Prince’s ginseng, Huai Shan, Xuan Shen, Mai Dong, Female Zhen Zi, Sheng Di Huang, Di Bone Bark, Ge Gen, Dan Shen, Mulberry seed, smallpox powder) etc., can not only lower blood sugar and improve insulin resistance to a certain extent, but also improve symptoms such as dry mouth and excessive drinking, fatigue, and delay and reduce chronic complications. Patients with IGT who are fat, often accompanied by hyperinsulinemia, at this time is not a lack of fluid, but too much fluid, and this excess fluid has often deteriorated and can not play a normal moistening role, just like the clear river water has become flood (turbid) water, not only for use, but for harm, is one of the culprits leading to cardiovascular disease. To treat IGT people with hyperinsulinemia or type 2 diabetes, we should follow the example of the Great Yu in treating water. We should take various methods such as draining, fixing the dike, dividing the flood and clearing the source, so as to restore the fluids to normal. The main purpose of draining is to smooth out the pivotal mechanism (emotions, stress, etc.) and regulate qi and channel stagnation, so that qi, blood and fluids can run smoothly. The treatment can be Xiao Chai Hu Tang, Chai Hu Gui Zhi Tang, Si Wei San, etc.; Fen Hong is to dissolve water, dampness, turbidity, phlegm, drinks and other tangible evil. Mainly includes: 1, to percolate water and dampness, using Wu Ling San (Poria, Ze Di, Pig Ling, etc.), Chun Ze Tang, Ling Gui Zhu Gan Tang, Chai Ling Tang, etc.; 2, to aromatize dampness and turbidity, using Plus and Minus Zheng Qi San (Huo Xiang, Hou Pu, Chen Pi, Fu Ling, etc.), Ping Gastric San, and Ginseng and Bai Zhu San, etc.; solid dike is to cultivate the earth, mainly manifested in: 1, to warm the spleen and Yang, using Li Zhong Tang (Ginseng, Gan Jiang, Bai Zhu, etc.), Gui Bai Li Zhong Tang; 2, to benefit the Spleen qi, with the formula of tonifying Zhong Yi Qi Tang (Huang Qi, Bai Zhu, Ginseng, Radix Angelicae Sinensis, Sheng Ma, Chai Hu, etc.), Yi Qi Smart Tang, etc.; 3. Strengthening the spleen and transportation, with the formula of Ping Gastric San (Cang Zhu, Hou Pu, Chen Pi, etc.), Bao He Tang, Park Ginger, Xia Cao Ginseng Tang, etc. Correcting the origin. As Ke Qin, a famous expert of the Qing Dynasty, said: “Strengthen the Yang to eliminate the Yin and shade, and expel the flow of dirt to clear the water source”. That is, the use of heavy doses of Zhen Wu Tang (cooked with Radix et Rhizoma Polygoni, dried ginger, etc.) and Si Wei Tang, etc. to warm and strengthen the kidney yang. If you retain a portion of yang, you retain a portion of vitality.
