A duodenal ulcer is a sore that develops in the lining of the duodenum, which is the first segment of the small intestine. It occurs when stomach acid breaks down the protective mucosal barrier, allowing the acid to damage the tissue beneath. Unlike gastric ulcers (which appear in the stomach), duodenal ulcers often produce pain a few hours after eating or during the night.
He reviews your symptoms, NSAID or aspirin use, alcohol and tobacco habits, stress factors, and overall health history.
We perform a urea breath test, stool antigen test, or blood antibody test to detect Helicobacter pylori infection.
Using a thin, flexible camera, Dr. Rishi directly inspects the stomach and duodenum lining for ulcers, bleeding, or inflammation.
If indicated, small tissue samples are taken to rule out malignancy and confirm H. pylori presence.

Duodenal ulcers form in the first part of the small intestine (duodenum), while gastric ulcers occur in the stomach. Pain from duodenal ulcers typically comes a few hours after eating, whereas gastric ulcer pain often worsens with meals.
With proper treatment including medications like PPIs and H. pylori eradication most duodenal ulcers heal within 4 to 8 weeks.
The general code for an unspecified duodenal ulcer without bleeding or perforation is K26.9. Different codes apply if there is bleeding or perforation.
Complications like severe bleeding or perforation are rare but can be serious. Prompt diagnosis and treatment by a specialist reduce these risks.
Dr. Chadha uses endoscopy to visualize the ulcer, tests for H. pylori (breath, stool, or blood), and may order imaging (X-ray or CT) if needed.
If you experience persistent abdominal pain, unexplained weight loss, vomiting blood, or black/tarry stools, schedule an appointment with Dr. Rishi Chadha for evaluation and care.
