More about Gastroenterology
Gastroenterology is the study of the normal function and diseases of the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver.
Gastroenterology involves a detailed understanding of the normal action (physiology) of the gastrointestinal organs including the movement of material through the stomach and intestine (motility), the digestion and absorption of nutrients into the body, removal of waste from the system, and the function of the liver as a digestive organ.
It includes common and important conditions such as colon polyps and cancer, hepatitis, gastroesophageal reflux (heartburn), peptic ulcer disease, colitis, gallbladder and biliary tract disease, nutritional problems, Irritable Bowel Syndrome (IBS), and pancreatitis. In essence, all normal activity and disease of the digestive organs are part of the study of Gastroenterology.
A gastroenterologist specialises in and treats diseases that affect the gastro-intestinal tract or gut, such as:
- Oesophagitis, gastritis, peptic ulcer disease and duodenal ulceration – all these conditions involve a degree of erosion or ulceration of the lining of the proximal gut generally causing pain, classically a burning, gnawing pain worse after eating
- Inflammatory bowel disease like Crohn’s disease or ulcerative colitis – these involve ulceration of the lower gut
- Liver problems such as hepatitis (inflammation of the liver from many different causes) and liver cirrhosis (scarring again from numerous possible causes)
- Malignancy (cancer) and benign (non-cancerous) tumours of the gut – like stomach and bowel cancer
- Investigation of bleeding from the gut, or abdominal pain.
Treatment often involves medications which may be prescribed on a short term or long term basis. If an operation is required generally you will be referred to a surgeon.
Some procedures a gastroenterologist performs include:
- Endoscopy
- Colonoscopy
- Biopsy.
