Helicobacter pylori ​

 

Helicobacter pylori (or H.pylori) is one of the commonest long-term bacterial infections worldwide, affecting up to 50-70% in some parts of the world. In Singapore, it has been estimated that 31% of the population has been infected by H.pylori. Fortunately, this infection is becoming less common with improvement in hygiene standard in many parts of the world. 

​

H.pylori can result in gastritis (stomach lining injury), ulcer as well as stomach cancer. In fact, 80% of stomach cancer can be attributed to H.pylori infection. Successful treatment of H.pylori can reduce risk of stomach cancer. Typical symptoms of H.pylori infection include nausea, gastric discomfort or gastric pain. 

​

There are a few test options to diagnose this infection: urea breath test, blood test and gastroscopy. Treatment involves combination of effective antibiotics and anti-acid medication.
