The performance of inflammatory bowel disease in children is often less typical than in adults, and children are in a critical period of growth and development, inflammatory damage to the intestinal tract can lead to malabsorption of nutrients, which can easily lead to growth retardation such as lack of growth and weight loss, which often leads to psychological disorders, introversion and isolation and other psychological problems, parents need to pay attention to. Unlike general enteritis, the cause of inflammatory bowel disease is still unclear and may be related to genetics, environment, intestinal flora and autoimmune function.
