Can Helicobacter help with longevity?

Whether Helicobacter pylori can promote longevity is scientifically controversial. H. pylori is a bacterium that colonizes the stomach lining and is known to cause peptic ulcers and gastric cancer. Some epidemiological studies suggest a possible protective role against esophageal cancer and asthma, leading to speculation about a net benefit for longevity. However, the evidence is weak and conflicting. Most people with H. pylori infection are asymptomatic, but the risk of serious gastric disease generally outweighs any potential benefits. Modern longevity research focuses on inflammation reduction, metabolic health, and cellular repair – areas where H. pylori is more likely harmful. In summary, there is no robust evidence that H. pylori infection extends lifespan. Eradication therapy is recommended for symptomatic infections. For asymptomatic carriers without risk factors, the benefit of treatment is unclear. Beware of marketing claims portraying H. pylori as a 'longevity bug.'
