Helicobacter pylori

 

Helicobacter pylori(H. pylori) is a type of bacteria. These germs can enter your body and live in your digestive tract. After many years, they can cause sores, called ulcers, in the lining of your stomach or the upper part of your small intestine. For some people, an infection can lead to stomach cancer.

Infection with H. pylori is common. About two-thirds of the world’s population has it in their bodies. For most people, it doesn’t cause ulcers or any other symptoms. If you do have problems, there are medicines that can kill the germs and help sores heal.

As more of the world gets access to clean water and sanitation, fewer people than before are getting the bacteria. With good health habits, you can protect yourself and your children from H. pylori.

Symptoms

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.

Other signs of an ulcer include:

Bloating

Burping

Not feeling hungry

Nausea

Vomiting

Weight loss for no clear reason

Ulcers can bleed into your stomach or intestines, which can be dangerous to your health. Get medical help right away if you have any of these symptoms:

Stool that is bloody, dark red, or black

Trouble breathing

Dizziness or fainting

Feeling very tired for no reason

Pale skin color

Vomit that has blood or looks like coffee grounds

Severe, sharp stomach pain

It’s not common, but H. pylori infection can cause stomach cancer. The disease has few symptoms at first, such as heartburn. Over time, you may notice:

Belly pain or swelling

Nausea

Not feeling hungry

Feeling full after you eat just a small amount

Vomiting

Weight loss for no reason
