As we all know, eggs will hatch chicks after a certain period of time at a certain temperature, while eggs in the refrigerator will not see the same result no matter how long they are left. For example, the oranges in the West Mountain were fresh and sweet, but after transplanting to the South Mountain, the fruit became sour and astringent, and then returned to the West Mountain to regain its original color. Similar situations abound in our daily life. This shows that environmental factors play a catalytic role in the change of the internal properties of substances. The same is true to a certain extent for the development of diabetes. We know that diabetes is a polygenic disease with a certain degree of heredity. Anyone carrying the genes that cause diabetes is likely to develop the disease, but which member of the family is the first to be “hit” and become a pre-disposed person depends on whether he or she has the “right” environmental conditions. So, what are the environmental factors that predispose to diabetes, other than genetic qualities? The risk factors for diabetes are broadly summarized as follows: 1. pre-diabetic (blood glucose has risen above normal levels, but has not yet reached the blood glucose level for the current diagnosis of diabetes); 2. overweight/obese, family history of diabetes; 3. too little exercise (<30 minutes per day, <3-5 times per week); 4. psychological stress; 5. disease status: recurrent infections, history of stroke, history of coronary heart disease, hypertension, hyperlipidemia, anxiety; 6. Hypertension, hyperlipidemia, anxiety; 6, women who have had gestational diabetes or delivered a huge fetus; 7, long-term use of drugs that affect glucose metabolism: anxiolytics, glucocorticoids; 8, increased age (old age is a high prevalence of diabetes, but age is not an absolute risk factor, and the onset of diabetes is now significantly younger). Hypertension, hyperlipidemia, anxiety disorders; in short, although the first to be hit is a misfortune, but also to the rest of the family and we "bystanders" a "warning", if we still do not know what to learn from it, tomorrow may be another If we don't learn something from it, we may be another "insider" tomorrow, and that will be a greater misfortune for society. Except for genetic factors and age, which cannot be changed, many of the above environmental factors are acquired and can be changed. By controlling the acquired factors, i.e. environmental factors, abandoning bad habits (overeating, smoking and drinking, good food and laziness), being open-minded and generous, and having a balanced mind, is by far the most effective way to prevent diabetes.
