Question
How are the symptoms of pediatric phenylketonuria?
Answer
The symptoms of phenylketonuria in children mainly manifest as abnormal body odor. Due to an abnormal metabolism of phenylalanine in the body, phenylacetic acid and phenylacetaldehyde are produced, which are excreted through sweat and urine, resulting in a distinctive musty or mouse-like smell. In addition, there may also be digestive problems such as diarrhea or constipation. The treatment of phenylketonuria primarily involves dietary control, limiting the intake of phenylalanine. When preparing the diet, it is necessary to increase the intake of fatty foods such as lard, sesame paste, candy, and sweets according to the child’s age and absorption capacity. At the same time, ensure an adequate intake of inorganic salts and vitamins. In winter, foods such as sweet potatoes, carrots, and yams can be used to replace staple foods to meet energy needs. The diet should be as varied as possible to ensure balanced nutrition and increase the intake of fresh vegetables and fruits according to the condition.
