Pediatric polyphagia, also known as indigestion, is a very common condition in the growth and development of children. Some children may also suffer from indigestion due to lack of zinc and other nutrients. Symptoms of paediatric anorexia are mostly manifested as lack of food and drink, abdominal distention and fullness, nausea and vomiting, and irregular bowel movements. Parents should provide a quiet and comfortable treatment environment for their children to avoid tension and anxiety. For diet, choose easy-to-digest foods such as vegetables, tofu, rice porridge and noodle soup. You can also take some medications that promote gastrointestinal peristalsis, such as Kid’s Spleen Health San, etc. In addition, you can also ease the discomfort of children through Chinese medicine massage and taking Chinese medicine. Parents should help their children build a good dietary structure in general, for example, let them eat more vegetables and fruits, more calcium, iron, zinc, selenium and other nutrients, and cultivate good eating habits. Note that they should eat less snacks, less high-fat, high-protein foods, and pay attention to keeping warm to prevent the abdomen from being attacked by cold.
