Diagnosis

Differential diagnosis

Mainly identified with eating disorders. Eating disorders in children are a type of problem that is highly valued by parents and physicians. According to a survey of 528 only children, the incidence of eating disorders due to mental health problems was as high as 78.64%. The main reasons were improper feeding methods, excessive love, excessive dependence, children's perseverance, eating with interest, lack of warmth and so on.

First, partial eclipse

Partial eclipse means that children only like to eat certain foods, not other foods. Children's partial eclipse and the eating habits of parents and those around them, as well as the daily comments of adults on food, are related to the child's psychologically good impression. If some parents have serious partial eclipse habits, they even impose their own preferences on their children. Some parents only pay attention to adding protein to their children, while ignoring vegetables and fruits rich in trace elements and vitamins. Another reason for children's partial eclipse is that parents do not understand the basic knowledge of children's nutrition. The meals prepared for children are very monotonous. Monotonous foods are repeated many times, causing bad stimulation to children's nervous system, even if children love food. Eating too much can also cause disgust, which can cause a partial eclipse.

Second, anorexia

Anorexia is a serious form of appetite suppression. The occurrence of anorexia in children is related to the influence of internal and external environment. If you are eating, some unpleasant things or unpleasant sounds can cause appetite suppression and even anorexia. Most notably, there is a serious eating disorder characterized by anorexia in children and adolescents, which is clinically known as anorexia nervosa. This is a type of eating disorder that deliberately diets to significantly reduce weight. This problem most often occurs in adolescent women. At first, patients worried that their body was fat, and some people thought that they were too fat when they were obviously thin, so they took the initiative to control their food intake, or excessive exercise, vomiting, diarrhea and other means to lose weight. In severe cases, the body weight can be reduced by more than 25%, eventually leading to malnutrition, metabolism and endocrine disorders. Although the exact cause of the disease is unknown, many scholars believe that psychosocial and cultural factors have a clear relationship with the disease. This may be related to the blind pursuit of slimness among young people in recent decades.

Third, bulimia

Bulimia refers to a seizure, inability to control a large amount of food in a short period of time. These patients have unstoppable appetite for eating, at least twice a week, each time eating a lot, if they do not get a chance to eat, they will be flustered, restless, and complain of strong hunger.

Fourth, the eclipse

The eclipse refers to persistent biting of non-nutritive substances such as dirt, dirt, stones and paper, which can lead to complications such as lead poisoning, intestinal obstruction and intestinal parasitic diseases. These patients are often accompanied by other forms of mental disorders, more common in patients with mental retardation and schizophrenia. Short-term eating behavior can also occur in intestinal parasites and trace element deficient. Adolescents before and after puberty may have a heterosexual diet.
