On the afternoon of June 14, a three-year-old child underwent endoscopic surgery for ten hours, because the child often complained of stomachache and nausea and vomiting. The mother took the child to the Children's Hospital affiliated to Zhejiang University School of Medicine for examination and found that the child had hair in his stomach. Finally, the doctor learned that children used to like to eat things in their mouths. After stopping them many times, the child did not appear in front of them. These are all eaten by adults. Even adults can relax and children can move. Moreover, it is even more difficult to prevent this from being eaten by adults. The deputy chief physician of gastroenterology said that it is also a disease that children like to pick up things and stuff them in their mouths. It's medically called pica. The main performance is that little things are quietly swallowed, and they like to lick with their tongues if they can't eat. The real harm of pica is all kinds of things that children eat by mistake, which will cause all kinds of harm to their internal organs. ? People with pica usually lack the necessary trace elements in their bodies. 70 kinds of trace elements that our human body needs, no matter which one has a very important role in the operation of the human body. When children are found to have this kind of situation, parents should go to the hospital to find out the reasons, choose the corresponding drugs under the advice of doctors, and pay attention to the nutritional balance of food in life. You need to pay more attention to the abnormal behavior of children in your life. With the development of society, children eat more and more kinds of snacks, which leads to partial eclipse, picky eaters and incomplete nutrition intake. It is suggested that children's snacks should be reduced and the types of recipes should be diversified. If children don't like it, they can change the food or change the way, so that children can take the initiative to eat. Don't force children to eat, which will make them psychologically resistant. It is suggested that parents, mothers and fathers should first appease and divert their children's attention and care when their children's diets are different, instead of blindly accusing and severely stopping them. It is not only to put away things that children are easy to eat by mistake, but also to pay attention and care from parents is the most important treatment plan.
