Complications of Helicobacter pylori peptic ulcer.

Helicobacter pylori infection can cause peptic ulcer, which can cause complications such as upper gastrointestinal bleeding, perforation, pyloric obstruction, canceration, etc.

1. Upper gastrointestinal bleeding

Peptic ulcer can cause bleeding on the ulcer surface of the stomach wall or duodenal wall, which can cause hematemesis, melena and other symptoms.

2. Perforated

peptic ulcer has not been effectively treated for a long time, which may penetrate the serous layer and cause perforation, increasing the risk of abdominal infection.

3. Pyloric obstruction

Peptic ulcer can lead to stenosis of the pyloric site, resulting in gastric emptying disorders, vomiting, abdominal distension and other symptoms.

4. Canceration

Long-term peptic ulcer can lead to repeated damage and repair of gastric mucosa, which is easy to increase the risk of canceration.
