Helicobacter pylori infection
Helicobacter pylori causes an infection of the mucous membrane of the stomach known as chronic gastritis, which can remain stable for years or can develop into atrophic gastritis (anacidic stomach).
Risks associated with Helicobacter pylori
In about 10-20% of all patients, Helicobacter pylori infection leads to the development of peptic or duodenal ulceration over the years and increases the risk of gastric cancer 2 to 6 fold. Helicobacter pylori efficiently produces acetaldehyde from the sugar and alcohol contained in food.
Helicobacter pylori symptoms
The infection is usually asymptomatic. However, it may cause some sort of non-specific dyspeptic symptoms, especially during meals. Helicobacter pylori infection is thought to cause non-specific dyspeptic symptoms in patients without peptic ulcer disease too. However, this link is yet to be clearly demonstrated.
Helicobacter pylori infection predisposes individuals to peptic ulceration and increases the risk of gastric cancer.
