The Claim
In adults aged 30 to 70 years, Helicobacter pylori IgG antibody seropositivity is associated with a slightly higher prevalence of thyroid peroxidase antibody positivity, with an adjusted odds ratio of 1.02 (95% CI: 1.00–1.03), indicating a small but statistically significant correlation in a Korean population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 30 to 70 in Korea, the presence of antibodies against Helicobacter pylori is associated with a slightly higher rate of antibodies against thyroid peroxidase.
See the scientific wording
In adults aged 30 to 70 years, the presence of Helicobacter pylori IgG antibodies is associated with a slightly higher prevalence of thyroid peroxidase antibody positivity (8.6% vs. 7.0%), with an adjusted odds ratio of 1.02 (95% CI: 1.00–1.03), suggesting a small but statistically significant correlation between H. pylori seropositivity and autoimmune thyroid markers in a Korean population.
An infection in the stomach triggers the immune system to make antibodies against a bacterial protein that looks similar to a protein in the thyroid. These antibodies mistakenly attack the thyroid protein, leading to the presence of antibodies that target the thyroid.
What the research says
1 studyStudy: Association between thyroid autoimmunity and Helicobacter pylori infection
People who had a past H. pylori stomach infection were slightly more likely to have blood markers showing their immune system was attacking their thyroid, even after accounting for age and gender. But this doesn't mean the infection causes the thyroid problem — just that the two tend to show up together.
