Is Helicobacter useful for Haut?

The question of whether Helicobacter pylori (H. pylori) is useful for skin health is not clearly answered by current science. H. pylori is primarily known as a stomach pathogen causing gastritis and ulcers. Some studies suggest associations with skin conditions like rosacea or chronic urticaria, but mostly as a potential trigger rather than a protective factor. There are speculative hypotheses about immunomodulatory effects on the skin, but evidence is weak and contradictory. In clinical practice, H. pylori is not considered beneficial for the skin; eradication is recommended when infection is confirmed and symptomatic. MyBody-X does not offer a specific test for H. pylori in relation to skin. Consumer genetic or microbiome tests detecting H. pylori should be interpreted cautiously: a positive result from stool or breath tests does not imply a skin benefit. The current evidence does not support tolerating or promoting H. pylori for skin purposes. Safety note: untreated H. pylori infection can lead to gastric cancer over the long term. Therefore, labeling this bacterium as 'useful' is premature and potentially dangerous. In summary, the evidence is unclear, and any benefit for the skin is unproven.
