Gastroenterology is the medical specialty that focuses on the prevention, diagnosis, and treatment of diseases of the digestive system, a complex and essential system for nutrition and overall health, which anatomically includes the gastrointestinal tract (esophagus, stomach, small intestine, colon, rectum, anus) and associated organs (liver, gallbladder, bile ducts, and pancreas). Our specialists address a wide range of conditions, both acute and chronic, that are very common in the population, such as gastroesophageal reflux disease, gastritis, ulcers, irritable bowel syndrome (IBS), chronic inflammatory bowel diseases (IBD, such as Crohn’s disease and ulcerative colitis), celiac disease, diverticular disease of the colon, viral and metabolic hepatitis, liver cirrhosis, and pancreatitis. The diagnostic process is based on a thorough medical history and examination, supplemented by laboratory tests (liver function, inflammation markers, celiac disease tests) and, most importantly, advanced endoscopic procedures such as gastroscopy and colonoscopy. These allow direct visualization of the mucosa, the performance of biopsies to confirm histological diagnosis, and the execution of operative procedures.
