Gastroenterology is the medical specialty that focuses on the functioning and diseases of the digestive system. The gastroenterologist's role is to identify, diagnose, treat, and prevent diseases of the digestive system, which includes the oesophagus, stomach, small and large intestines, rectum, and related organs such as the liver, gallbladder, and pancreas.
To make a diagnosis, gastroenterologists perform various tests such as endoscopic procedures (gastroscopy, colonoscopy), ultrasound, and laboratory tests. Gastroenterology plays a crucial role in the early detection and treatment of abdominal pain, digestive issues, bleeding, and more serious diseases.
If there is a family history of colorectal cancer, stomach cancer, or other digestive system cancers, especially after the age of 50, regular screening is recommended, including colonoscopy or other diagnostic methods.
The following symptoms may require urgent medical intervention:
What do these mean exactly?
Gastroscopy – Also known as an upper endoscopy, this is a diagnostic procedure in which the doctor inserts a thin, flexible tube (endoscope) through the mouth into the oesophagus, stomach, and duodenum (the initial part of the small intestine). The endoscope has a camera at its tip that transmits live images of the examined organs, allowing for a detailed examination of the upper digestive tract. The procedure can be performed while the patient is awake or under sedation.
Colonoscopy – A diagnostic procedure in which the doctor inserts a long, flexible endoscopic instrument (colonoscope) through the anus into the large intestine to examine its inner lining. The camera at the end of the colonoscope transmits live images to a monitor, allowing detailed examination of the bowel lining, removal of polyps, and tissue sampling (biopsy). This procedure can also be performed while the patient is awake or sedated.
Breath tests – The H₂ (hydrogen) and CH₄ (methane) breath tests are non-invasive diagnostic methods used to diagnose digestive problems such as lactose, fructose, and sorbitol intolerance, small intestinal bacterial overgrowth (SIBO), and malabsorption disorders. Undigested carbohydrates (such as lactose, fructose) that reach the colon are fermented by bacteria, producing hydrogen (H₂) and methane (CH₄) gases, which enter the bloodstream and can be exhaled through the lungs. The test measures changes in these gases. H₂ and CH₄ breath tests are an effective tool for diagnosing digestive disorders, carbohydrate intolerances, and bacterial overgrowth, helping to determine the appropriate diet or treatment.
