Helicobacter pylori is a bacteria found in the lining of the stomach or duodenum of a surprising number of people. Its discovery, back in 1983, revolutionised medicine almost overnight because, although most people with H.pylori have no problems, in a significant proportion it can lead to indigestion or peptic inflammation/ulceration. Thus, although we still do not fully understand how this bacteria can cause stomach acid to damage the lining of the gut, antibiotic treatment to rid this infection has cured many people of their indigestion or stomach/duodenal ulcers.
A generation ago, many people would have laughed at the thought that antibiotics might cure indigestion - certainly many doctors were initially sceptical. However, it is now routine to test for this bacteria when people undergo a gastroscopy (OGD see peptic inflammation) as part of investigations for indigestion. Similarly some people who have been taking regular acid-suppressing medication for a long time to control their stomach symptoms, have been able to stop taking this medication after being treated (where this infection has been found to be present).
Unfortunately, not all people who suffer from indigestion or who have ulcers are infected with H.pylori and not all people who have the bacteria are cured of their symptoms after treatment to remove it. Your doctor will be able to advise whether, in your particular case, testing for H.pylori is a good idea.
H.pylori is a fascinating germ, able to resist the stomach acid which normally kills bacteria. However, there remains, a lot about which we are unclear. For example, we still do not know exactly how people become infected with H.pylori, although it is probably caught in childhood following contact with the vomit or faeces from an infected person. This is therefore one more reason to take care to wash your hands after using the toilet.
In order to effectively treat this bacteria a course of 'eradication therapy' is needed. Eradication therapy typically comprises a combination of three medicines, two antibiotics and an acid-suppressing medication, which need to be taken regularly for one week. Combination (triple) therapy is very effective, curing the infection in 90% of those treated. Unfortunately about a quarter of people develop some form of, usually mild, side-effects with the medication including nausea, diarrhoea or headaches. Whenever possible though, it is wise to complete the course of treatment as it can save you from taking indigestion remedies long-term.
