There are already hundreds of millions of people with diabetes in China. The best we know about the pathogenesis of type 2 diabetes is that a large intake of carbohydrates leads to a “roller coaster” of blood glucose and insulin, resulting in “insulin resistance”, which will slowly develop over time and eventually become a disease. When the supply of basic nutrients is hindered, it is more likely to cause disorders of cellular glucose metabolism, which can lead to the development of diabetes when the glucose content in human plasma rises abnormally and the cell population declines and organ tissue lesions are damaged. If glucose is the coal used to generate electricity, the cells that consume glucose are the “boiler room”, and the liver and muscles that temporarily store glucose are like the “warehouse”. Every time we eat, a group of “coal distributors” called insulin will move the glucose in the blood system to the “boiler room” and store all the excess in the warehouse for emergencies. When people start to overeat and have a series of unhealthy eating habits, the coal in the logistics line becomes more and more, and the amount of insulin also increases, resulting in the boiler room not being burned out and the warehouse being filled, and many blood glucose delivered to the door being rejected, resulting in more and more blood glucose accumulating in the blood, which in turn produces hyperglycemia and diabetes. Why are most diabetics fat? Long-term persistent obese people, the incidence of diabetes significantly higher, can be as high as four times as much as the general population. In type 2 diabetics 80% are obese, 60% of obese patients have low glucose tolerance, so obesity and diabetes “inseparable”. The fundamental reason is that there is a special “soil” in the body of obese people, called insulin resistance. Insulin is the main hypoglycemic hormone in the human body. After eating, people will absorb a large amount of sugar into the blood, through the blood circulation to all parts of the body. Only by relying on insulin can blood sugar enter the cells and be used by the body, while the level of glucose in the blood is maintained within a certain range by insulin. One of the causes of diabetes is obesity, so why do diabetics get thinner and thinner? Some diabetics may even experience a greater appetite and increase in food consumption, but lose weight instead! Many people are baffled by the fact that weight loss is one of the typical symptoms of diabetes. When the body’s blood sugar is higher than the renal sugar threshold, a large amount of glucose will be excreted from the body with the original urine, when the concentration of organic matter in the original urine is higher than the cells, a large amount of water will pour into the urine, and then excreted from the body, the body loses a lot of water, the body water content is relatively low, the body will be obviously thin, that is, polyuria. In diabetic patients, there is a relative or absolute shortage of insulin in the body, and the cells cannot enter the cells through the medium of insulin to be digested and absorbed by the body, so the phenomenon of “cell starvation” occurs. When cells are unable to use blood sugar, they burn fat and protein and use the phenomenon of gluconeogenesis to produce a portion of blood sugar to maintain basic life activities! When a large amount of fat and protein is consumed, the body slowly loses weight, the body’s immune system decreases, and fatigue and lack of energy ensues, i.e. weight loss.
