Best Gastroenterology Doctors in Turkey

Turkey's best gastroenterology doctors specialize in the diagnosis and treatment of digestive system, liver, pancreas, and gallbladder disorders. These experts provide comprehensive, minimally invasive, and patient-centered care for conditions such as acid reflux (GERD), irritable bowel syndrome (IBS), liver cirrhosis, fatty liver disease, pancreatitis, hepatitis B/C, inflammatory bowel disease (Crohn's/ulcerative colitis), and colorectal cancer.

Turkey's premier gastroenterologists are trained at leading international institutions like Hacettepe University and Istanbul Medical Faculty, practicing in world-class JCI-accredited hospitals equipped with cutting-edge technology for high-definition endoscopy, colonoscopy, ERCP with spyglass cholangioscopy, endoscopic ultrasound (EUS), liver elastography (FibroScan), capsule endoscopy, and AI-assisted polyp detection.​

With expertise in both medical management (biologics for IBD, antivirals for hepatitis) and interventional gastroenterology (ESD for early cancers, balloon enteroscopy), they deliver accurate diagnoses and effective, personalized treatment plans. Whether suffering from chronic digestive issues like refractory GERD or needing specialized liver care for NASH/cirrhosis, Turkey offers affordable (60-80% less than West) and globally trusted GI treatment options.

International patients from Europe and the Middle East regularly travel to Turkey for access to advanced procedures like radiofrequency ablation for Barrett's esophagus, experienced doctors like Prof. Zeynel Mungan, and excellent success rates in complex cases.
