Sometimes ulcers can cause complications, such as bleeding, perforation, penetration, or obstruction. That's why it's important to treat an ulcer, even if you have one that isn't causing any symptoms.
Most peptic ulcers without complications heal, regardless of the cause. But an ulcer is likely to come back if you have an H. pylori infection that is not successfully treated. Recurring ulcers caused by reinfection with H. pylori are not common in the United States, except in areas that are overcrowded or have poor sanitation.
Ulcers in the stomach (gastric ulcers) often heal more slowly than ulcers in the upper small intestine (duodenal ulcers).
