Pediatric gastroenterology is a medical specialty that focuses on diagnosing and treating digestive system disorders in infants, children, and adolescents. It deals with conditions affecting the esophagus, stomach, intestines, liver, and pancreas. Common issues include gastroesophageal reflux, constipation, diarrhea, celiac disease, inflammatory bowel disease, and liver disorders. Children with symptoms like abdominal pain, poor appetite, vomiting, or growth problems are often referred to pediatric gastroenterologists for evaluation. Diagnosis involves medical history, physical examination, lab tests, imaging, and sometimes endoscopy. Treatment may include dietary changes, medications, and nutritional support. Pediatric gastroenterologists work closely with families to manage chronic conditions and improve quality of life. Early diagnosis and proper care are essential to prevent complications and support normal growth and development in children with digestive disorders.
