About the department

The pediatric gastroenterology department at Teknon Medical Center Barcelona provides comprehensive care to patients with various gastrointestinal, nutritional and liver disorders. The department offers the most varied and specialized tests to diagnose gastroenterological conditions, including capsule endoscopy and advanced motor procedures using high-resolution equipment. After complex diagnostic measures, doctors choose individual therapy following national and international standards. Paediatricians strive to improve their knowledge and participate in many congresses on pediatric gastroenterology, hepatology and nutrition. Experienced doctors and caring medical staff try to create the most friendly atmosphere so that the child and parents feel comfortable.

The gastroenterologists and hepatologists work alongside certified nurse practitioners and nutritionists to help children with chronic abdominal pain, reflux, constipation, vomiting, nausea, etc. The department also treats special conditions, including inflammatory bowel disease (Crohn's disease and ulcerative colitis), biliary atresia, hepatitis, celiac disease, eosinophilic gastrointestinal disease, obesity, and short bowel syndrome.
