Helicobacter Pylori is a bacteria that resides in the mucous layer of the lining of the stomach. It produces an enzyme Urease that can cause inflammation of the stomach lining (gastritis). It is responsible for a vast majority of Gastric and Duodenal Ulcers.

Peptic Ulcer refers to ulcers (break in mucosa or lining) caused by acid. It is a world wide problem and is caused by:

1. Helicobacter infection: This is a bacteria that is transmitted by the feco-oral route and settles in the mucous layer of the stomach and can cause ulcers in the stomach and the duodenum (first part of the small intestine).
2. Nonsteroidal Anti-inflammatory agents: Drugs like Motrin, Ibuprofen, Alieve and Aspirin can cause ulcers in any part of the GI Tract (stomach, duodenum, small bowel, colon).
