Gastroenterology is the part of medicine concentrated on the digestive system and its issues. Diseases affecting the gastrointestinal tract, which incorporate the organs from mouth into anus, along the alimentary canal, are the focal point of this speciality. Doctors practicing in this field are called gastroenterologists. They have usually finished around eight years of pre-clinical and clinical education, a year-long internship, three years of an interior medication residency, and three years in the gastroenterology association. Gastroenterologists play out various symptomatic and helpful methods including colonoscopy, esophagogastroduodenoscopy, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, and liver biopsy. Some gastroenterology learners will finish a fourth-year in transplant hepatology, progressed interventional endoscopy, inflammatory bowel disease, motility, or different topics.
