Fatih Oguz Onder is a Turkish gastroenterologist and professor. He sees patients at Acıbadem Atakent Hospital in Istanbul (Küçükçekmece district) and is engaged in academic work at Acıbadem Mehmet Ali Aydınlar University.
His clinical focus is digestive system diseases: inflammatory bowel diseases (Crohn’s disease, ulcerative colitis), gastritis, peptic ulcer disease, gastroesophageal reflux disease, liver diseases (autoimmune hepatitis, chronic viral hepatitis B, C, D), biliary tract diseases, and chronic pancreatitis.
A particular area of strength is endoscopy. He performs diagnostic and therapeutic upper gastrointestinal endoscopy, colonoscopy, and percutaneous endoscopic gastrostomy (PEG) placement. Endoscopic procedures are a key method for the early diagnosis of stomach cancer and the detection of precancerous changes in the esophagus, stomach, and colon.
He has a strong scientific background: publications in leading international journals on hepatology — Clinical Infectious Diseases, BMC Infectious Disease, Rheumatology International. He completed his subspecialty in gastroenterology at Ankara Türkiye Yüksek İhtisas Training and Research Hospital — one of the most prestigious specialized gastroenterology hospitals in Turkey.
For a patient who needs consultation regarding complex digestive system diseases or an endoscopic examination (including preventive colonoscopy, diagnosis of suspected early stomach or esophageal cancer), this is a well-founded choice in a private academic clinic.
