Recently, there have been more patients consulting about poor appetite in children, and I would like to discuss this issue. Appetite is one of the basic desires of human beings. Without appetite, human beings cannot survive and reproduce. Generally, healthy children have a normal appetite, except for diseases. However, with the recent increase in the number of only children, the number of pediatric anorexia is also increasing. Appetite, which is the desire to eat, is governed by the nervous system. In the case of an empty stomach, the stomach and intestines stimulate the appetite center of the brain by contracting to excite and produce the desire to ingest food; on the contrary, when the stomach is filled with food, the stomach wall stretches and stimulates the appetite center to suppress, and the appetite disappears. At the same time, the person’s mental condition also directly affects the appetite, such as in the case of mental tension, even if the fasting does not want to eat, that is, the mental happy to stimulate the appetite center, and vice versa to inhibit the appetite center. In addition, human blood and body fluids also have an impact on appetite, as low blood sugar stimulates the nerve center to produce appetite, and conversely, high blood sugar suppresses appetite. Therefore, in order to stimulate children’s appetite, we should start from the following aspects. First, do not let children eat snacks, children in each meal to maintain an empty stomach, to produce a ‘hungry state’ to stimulate the appetite center of the brain to produce appetite, so that children ‘hunger to eat’, so as to prevent the occurrence of paranoia, but also to make children feel after eating Physical and emotional satisfaction after eating, this satisfaction can promote the appetite of this function to further develop and perfect. Second, control the amount of sugar eaten by children, especially 1-2 hours before meals, it is best not to eat food containing sugar, so that children’s low blood sugar directly stimulates the nerve center to produce appetite. Third, let the child eat in a pleasant environment, never reprimand the child during meals, because strong external stimuli will make the child nervous, resulting in reduced secretion of digestive juices and loss of appetite. Fourth, to prevent children in the diet of rebellious psychology, forcing children to eat a certain food, children will produce a rebellious psychology, more affect the appetite, the more young children, the more serious this situation, ‘you let me eat, I do not eat’, or cope with a little, common parents say; ‘you give me Put this bit of food to eat’, the child is ‘I give you to eat it’, originally appetite is a basic human desire, but by the child as a task to complete, then lost the original meaning of eating, which has a negative impact on the normal development of the appetite of children. In short, the appetite of children is not developed by scolding, reprimanding and other means to force, nor by spoiling, pampering to cultivate, but by scientific feeding, patient guidance to stimulate, to perfect.
