Gastroenterology

What is Gastroenterology?

Gastroenterology is the medical speciality focused on diagnosing, managing, and treating conditions affecting the digestive system — including the oesophagus, stomach, liver, pancreas, gallbladder, small intestine, and large intestine (colon).

Your digestive health plays a vital role in your overall well-being. Symptoms such as abdominal pain, changes in bowel habits, persistent heartburn, or rectal bleeding may indicate underlying issues that require expert assessment.
