Myths vs facts: Helicobacter and stress

There are many myths about Helicobacter pylori and stress. Fact: H. pylori infection is caused by bacteria, not stress. However, chronic stress can weaken the immune system and gastric mucosal defense, potentially increasing susceptibility or exacerbating symptoms. Some studies show a modest association between stress and peptic ulcers, but the evidence is moderate at best. Stress does not cause the infection; it may influence disease progression. Consumer DNA tests do not diagnose H. pylori; stool or breath tests are used. MyBody-X does not offer H. pylori testing. Bottom line: treat the infection with antibiotics, manage stress for overall health, but don't confuse correlation with causation.
