Jiangbei District, a 4-year-old boy Chao Chao (a pseudonym) recently severe constipation, his parents took him to the hospital gastroenterology treatment, the condition has not improved. Finally, the psychiatrist quickly found Chao Chao constipation "knot", because in the kindergarten defecation soiled trousers criticised by the teacher, Chao Chao from then on do not dare to go to the toilet in the kindergarten before suffocating out of the disease.

　　Yesterday, in the Children's Hospital Psychology Department treatment room, Ms Liu said her son Chao Chao on the crying and laughing. Ms Liu said, a month ago, he noticed that the child is a little bit wrong. Every time to the kindergarten to pick up Chao Chao after school, Chao Chao will always run towards home, the first thing to do is to enter the toilet.

　　Ms Liu noticed that Chaochao every time to take off his trousers on the side, no matter how cold the day is so. Later, Chaochao would always close the door when he went to the toilet, not letting anyone see. Strangely enough, Chaochao's breakfast is also decreasing. When the family asked why, Chaochao was evasive and didn't want to answer. Last week, Chaochao became constipated and didn't go to the toilet for a few days, so his family became anxious and took him to the Gastroenterology Department of the Children's Hospital. After a few days of medication, the constipation did not improve.

　　After the psychiatrist Wang Min patient enquiry, finally found Chao Chao constipation "knot". It turned out that a month ago, Chaochao defecated in the kindergarten and soiled his trousers, and was criticised by his teacher. Since then, he has not dared to defecate in the kindergarten, no matter how painful and difficult it is to hold back and go home.

　　Dr Wang Min reminded parents that when a child wets the bed and wets his trousers, parents and teachers should be tolerant and not scold him. Timid and low self-esteem of the child is scolded easily after the emergence of emotional disorders, long-term repression of the child's physical and mental health is extremely unfavourable.
