Simple obesity refers to the body’s intake of calories for a long time higher than the consumption of calories, thus causing fat accumulation of obesity. To put it simply, the fat that eats more and moves less is simple obesity. Simple obesity in the obese population accounted for as high as 95%. That is to say, most of the fat friends of obesity, basically is difficult to control their appetite. And where does appetite come from? Humans get energy through blood sugar in the blood, which comes from nutrients obtained from food by digestive organs such as the small intestine. A person can feel hungry due to a decrease in the concentration of blood sugar in the blood. This is the process by which human beings obtain energy and it is very normal. But why is it that fat people with simple obesity are always haunted by hunger, and they are hungry again in no time after they have eaten enough? It is likely that something is wrong with your blood, small intestine or other bodily functions! When the blood sugar concentration of the blood due to reasons such as heredity, has been lower than the normal concentration, it will be easy to feel hungry all the time. One of the presenting symptoms of low blood sugar is easy hunger. The immune system is also low. The second is low digestive tract function. The digestive function of the small intestine and the stomach can’t function properly, then it can’t convert the food into nutrients, which leads to the blood sugar concentration being low all the time. Of course there are other metabolic reasons. However, if it is difficult to control appetite for a long time, which leads to obesity, it is recommended to have a checkup in the hospital! Currently, stomach reduction surgery is able to reduce the secretion of hormones that stimulate the production of hunger by reducing the capacity of the stomach, which is applicable to all obesity. Weight loss surgery is the only long-term effective weight loss method for obese patients. It can eliminate obesity and regain weight from the root cause of hunger, which is more effective and has a lower rebound rate.
