With the improvement of people’s material living standards and the continuous westernization of their lifestyles, the incidence of diabetes in China is rising year by year, and now it is estimated that an average of 3,000 new diabetics are diagnosed every day, and the total number of diabetics in China has ranked second in the world. Diabetes is a lifelong disease that cannot be cured until now, and any drug or method that boasts of curing diabetes is irresponsible and deceptive. We have been engaged in the clinical and scientific research of diabetes for a long time, and in the course of our work, we have summed up a set of proven principles for the treatment of diabetes: “control your mouth, practice your legs, and use the right medicine”, referred to as the “nine words”. It is often said that “disease comes from the mouth, disaster comes from the mouth”, the onset of diabetes is very closely related to the acquired bad lifestyle, the first diabetes survey in 1980, the national incidence rate was only 0.67%, but now the incidence rate of diabetes in China has been close to 5%, in the case of ethnicity has not changed the incidence rate of such a rapid change. The rapid change in the incidence of diabetes in China is an indication of the important influence of environmental factors on the development of the disease. The high-calorie diet and the relative lack of physical activity in China nowadays have caused the long-term accumulation of high-calorie substances in the body. Since diabetes is acquired by the mouth, the key to treatment also starts from the mouth, and any treatment of diabetes is based on controlling the “mouth”. Diabetic doctors must pay attention to the dietary education of diabetes in the clinical treatment, do not rely too much on drugs, diabetes behavior treatment than drug treatment to be more effective. The second major factor in the development of diabetes is the reduction of physical activity, “life is exercise”, diabetic patients should pay more attention to exercise, because exercise itself can lower blood sugar, diabetes exercise therapy advocates soothing light to moderate exercise is appropriate, inactivity and strenuous exercise will have a negative impact on patients. “Ten thousand steps a day, health and longevity.” Diabetic patients should not be less than 10,000 steps per day, which is equivalent to a distance of about 10 miles, and the best way of activity is “brisk walking” or “jogging”, which requires slight sweating and panting after the activity. The patient can also count his or her own pulse, and the pulse after activity + age = 170, which is called moderate activity. Diet and exercise therapy are both active ways to lower diabetes, while medication is a passive treatment for diabetes, and there is no way out. The principle of diabetes drug treatment is “add drugs not add dose”, that is, the combination of several drugs to treat rather than simply use a drug and increase the dose, because diabetes drug toxicity is related to the dose. The clinical experience of more than 10 years, the increase of diabetes incidence in China is related to the proliferation of low liquor in recent years, low liquor is a product of the market economy, from a nutritional point of view low liquor is harmful to the human body, especially to the liver and pancreas damage is greater, here to advise readers not to greedy cup, know that each cup of wine is at the cost of your health. In short, there is no secret to the treatment of diabetes, as long as you really practice the “nine words” of “control your mouth, practice your legs, and use the right medicine”, you will definitely overcome diabetes.
