Duodenal Ulcer vs Gastric Ulcer: What's the Difference?
"Peptic ulcer" is the umbrella term for sores in the upper digestive tract. The two main types are named after where they occur.
Duodenal ulcers
These form in the duodenum, the first part of the small intestine just after the stomach.
- More common than gastric ulcers in many populations
- Very strongly linked to H. pylori
- Pain classically appears two to three hours after meals or at night, and may ease with eating
Gastric ulcers
These form in the stomach itself.
- Linked to H. pylori and anti-inflammatory painkillers
- Pain may come on soon after eating
- Can cause loss of appetite and weight loss
These patterns are general. Many people do not fit them neatly, so symptoms alone cannot identify the type.
Why the difference matters
- Follow-up: gastric ulcers are often re-checked by endoscopy after treatment to confirm healing and, rarely, to rule out cancer. Duodenal ulcers are less often re-examined if symptoms resolve and H. pylori is cleared.
- Healing time: gastric ulcers can take a little longer to heal.
What both need
- H. pylori testing and treatment if positive, followed by a retest
- A review of painkillers
- Acid-reducing medicine for several weeks
- Stopping smoking and limiting alcohol
Key takeaway
Duodenal and gastric ulcers share the same main causes and treatments, but gastric ulcers usually need closer follow-up. Ask your doctor which type you have and what follow-up is planned.
