Helicobacter pylori infection

H pylori infection

Helicobacter pylori (H pylori) is a type of bacteria that infects the stomach. It is very common, affecting about two thirds of the world's population. H pylori infection is the most common cause of peptic ulcers. However, the infection does not cause problems for most people.

Stomach

The stomach is the portion of the digestive system most responsible for breaking down food. The lower esophageal sphincter at the top of the stomach regulates food passing from the esophagus into the stomach, and prevents the contents of the stomach from reentering the esophagus. The pyloric sphincter at the bottom of the stomach governs the passage of food out of the stomach into the small intestine.

Esophagogastroduodenoscopy (EGD)

Esophagogastroduodenoscopy (EGD) is a test procedure to examine the lining of the esophagus, stomach, and first part of the small intestine. The procedure uses an endoscope. This is a flexible tube with a light and camera at the end. A biopsy can be taken through the endoscope of any suspicious areas that are seen.

Location of peptic ulcers

A peptic ulcer is an open sore or raw area in the lining of the stomach (gastric) or the upper part of the small intestine (duodenal).
