Gastric Ulcer vs Duodenal Ulcer: Understanding the Differences

When comparing gastric ulcers and duodenal ulcers, one of the most notable differences lies in the timing and nature of the pain experienced. Gastric ulcers often cause discomfort shortly after eating. This pain typically presents as a burning or aching sensation in the upper abdomen, just below the breastbone or about two fingers above the navel. On the other hand, duodenal ulcers are more likely to cause pain when the stomach is empty, particularly at night or several hours after a meal. These ulcers are commonly associated with hunger pains or nocturnal discomfort.

Location of Pain and Common Symptoms

The location of the ulcer can also influence the type of symptoms experienced. Gastric ulcers are frequently found in the body of the stomach, near the gastric angle, or along the lesser curvature of the stomach. In contrast, duodenal ulcers most commonly occur in the duodenal bulb, which is the first part of the small intestine connected to the stomach. This distinction in location can help explain the differences in symptom patterns between the two types of ulcers.

Diagnostic Methods for Ulcer Differentiation

Accurate diagnosis of either gastric or duodenal ulcers typically involves the use of endoscopy, also known as gastroscopy. During this procedure, a flexible tube with a camera is inserted through the mouth to examine the lining of the stomach and the first part of the small intestine. A gastric ulcer will typically appear in the stomach's body, angular notch, or along the lesser curve, while a duodenal ulcer is most often found in the duodenal bulb. This visual distinction during endoscopy plays a crucial role in confirming the type of ulcer present.
