Is gastric ulcer contagious?

　　Gastric mucosal injury—caused by various factors—can lead to ulcer formation when the damage reaches a certain depth. So, is gastric ulcer contagious?

　　Is gastric ulcer contagious?

　　Gastric ulcer itself is not contagious. Whether or not it spreads depends primarily on infection with *Helicobacter pylori* (*H. pylori*). If an individual tests positive for *H. pylori*, the bacterium can be transmitted orally to others. However, *H. pylori* infection does not inevitably lead to gastric ulcer development. Thus, gastric ulcer is considered non-contagious; while *H. pylori* infection may cause gastritis, gastric ulcer, or even gastric cancer, the incidence of these conditions remains relatively low. Individuals testing positive for *H. pylori* must undergo active anti-*H. pylori* treatment. Moreover, they should use separate utensils from family members to minimize the risk of cross-infection.

　　The optimal approach to treating gastric ulcer begins with testing for *H. pylori*. If the test is positive, quadruple therapy (a combination of four medications) is required. If negative, no specific anti-*H. pylori* treatment is needed. Next, evaluate whether the patient experiences upper abdominal pain, acid reflux, heartburn, or bloating—and assess the nature of the pain (e.g., rhythmic or cyclical). If symptoms align with those typical of gastric ulcer and *H. pylori* testing is negative, proton pump inhibitors (PPIs)—which suppress gastric acid secretion by parietal cells—may be prescribed.

　　Dietary recommendations for patients include avoiding spicy and cold foods. After recovery, meals should be gradually reintroduced in a structured manner, and medications must be taken consistently as prescribed. We hope this information is helpful. Wishing you good health and happiness!
