People with H. pylori infections are more likely to have or develop hypertension, non-alcoholic fatty liver disease, and subclinical atherosclerosis. H. pylori infection may also increase the risk of developing irritable bowel syndrome (IBS), but more research is needed to confirm this association.[1][2][3][4][5]
H. pylori treatment may help to reduce IBS symptoms and is also associated with a reduced risk of gastric cancer. Some research shows that eradication therapy could increase the risk of developing gastroesophageal reflux disease, but other research suggests it has no effect.[5][6]
