H Pylori

Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, microaerophilic, spiral bacterium usually found in the stomach. Its helical shape is thought to have evolved in order to penetrate the mucoid lining of the stomach and thereby establish infection.

If you have an ulcer, you may feel a dull or burning pain in your belly. It may come and go, but you’ll probably feel it most when your stomach is empty, such as between meals or in the middle of the night. It can last for a few minutes or for hours. You may feel better after you eat, drink milk, or take an antacid.

If you have ulcers caused by H. pylori, you’ll need treatment to kill the germs, heal your stomach lining, and keep the sores from coming back. It usually takes 1 to 2 weeks of treatment to get better.
