What is an H. pylori infection?
Class: "Campylobacteria"
Family: Helicobacteraceae
Genus: Helicobacter
Order: Campylobacterales
Phylum: Campylobacterota
H. pylori (Helicobacter pylori) are bacteria that can cause an infection in the stomach or duodenum (first part of the small intestine). It’s the most common cause of peptic ulcer disease. H. pylori can also inflame and irritate the stomach lining (gastritis). Untreated, long-term H. pylori infection can lead to stomach cancer (rarely).
Can H. pylori spread from person to person?
Yes, H. pylori can spread from person to person. H. pylori are found in saliva, plaque on teeth and p**p. Infection can be spread through kissing and by transferring the bacteria from the hands of those who have not thoroughly washed them after a bowel movement.
Scientists think H. pylori also might be spread through H. pylori-contaminated water and food
What’s the association between H. pylori infection and stomach cancer?
If you have an H. pylori infection, you have an increased risk for stomach cancer later in life. If you have a strong family history of stomach cancer and other cancer risk factors, even though you may not have symptoms of a stomach ulcer, your healthcare provider may recommend being tested for H. pylori antibodies. In addition to screening and treatment, your provider may suggest some lifestyle changes, such as including more fruits, vegetables and fiber in your diet. Regular checkups with your provider and following their recommendations can reduce your cancer risk.
What are the symptoms of H. pylori infection?
Most children with H. pylori infection don’t have symptoms. Only about 20% do.
Symptoms and signs, if present, are those that arise from gastritis or peptic ulcer and include:
Dull or burning pain in your stomach (more often a few hours after eating and at night). Your pain may last minutes to hours and may come and go over several days to weeks.
Unplanned weight loss.
Bloating.
Nausea and vomiting (bloody vomit).
Indigestion (dyspepsia).
Burping.
Loss of appetite.
Dark stools (from blood in your stool).
