Gastroenterology is a branch of medicine that deals with the study and treatment of the digestive system and its associated disorders. This includes the diagnosis and treatment of conditions affecting the esophagus, stomach, small intestine, colon, rectum, pancreas, gallbladder, and liver.

Some of the most common conditions that gastroenterologists diagnose and treat include:

Acid reflux disease (also known as gastroesophageal reflux disease or GERD)


Irritable bowel syndrome (IBS)

Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis

Gallbladder disease



Celiac disease

Gastroenterologists use a range of diagnostic tests to help identify and diagnose these conditions, including colonoscopies, endoscopies, blood tests, and imaging studies such as CT scans and MRIs.

Treatment for gastroenterological conditions depends on the specific condition and its severity, but may include lifestyle changes (such as dietary modifications), medication, surgery, or a combination of these approaches.
