LISTEN | The ultimate guide to understanding H. pylori disease: Why it matters

Helicobacter pylori (H. pylori) is a type of bacteria that infects the stomach. In the majority ofpeople, it causes no problems, however in 10-20% of people it can cause ulcers (or sores) andinflammation mainly in the lining of your stomach.

For some people (in 1-2%), an infection can lead to stomach cancer.

The disease is an important public health concern in Africa.

The African Helicobacter and Microbiota Study Group's founding president Prof Stella Smith and Prof Mashiko Setshedi elaborate further:

How do you get H. pylori? 

Although the mode of transmission is unclear, H. pylori is thought to spread by direct person-to-person through: 

• kissing, sharing contaminated utensils 

• contaminated food, water, and surfaces from inadequate handwashing after a bowel movement 

• contaminated water sources in the environment

Is H. pylori contagious? 

Yes. It is a transmissible infection (as explained above) either through direct contact from saliva, poor hygiene practices or contaminated environmental water sources.  

When to get emergency help 

Sometimes, the ulcers are so deep that they can erode the blood vessels supplying the stomach and cause bleeding. This is a serious and potentially life-threatening complication. Call your doctor if you have any of these symptoms: 

• bloody, dark red or black poop 

• dizziness or fainting
