A serious gastric ulcer requires surgery. A serious gastric ulcer refers to complications of gastric ulcer, such as gastric ulcer with bleeding, gastric ulcer with perforation, gastric ulcer with obstruction. It is likely that surgery is needed, especially if the gastric ulcer becomes cancerous, so it is necessary to strive for early surgery. For other gastric ulcer conditions, when there are no complications, conservative treatment with medication can achieve a cure, so please rest assured. Stomach ulcers are mainly treated with anti-ulcer drugs, such as oral acid suppressants combined with bismuth. If the gastric ulcer is caused by H. pylori infection, you can use a quadruple or triple therapy program to eradicate H. pylori treatment. Even if there is bleeding from gastric ulcer, the first step is to give drugs to suppress acid and stop bleeding. Only in case of severe bleeding, the need for surgical hemostasis will be considered after the failure of conservative drug treatment.
