The Claim
In patients with Graves' disease and cagA-positive Helicobacter pylori infection, eradication of Helicobacter pylori is associated with decreased thyroid-stimulating hormone (TSH) levels in individuals not receiving definitive thyroid treatment.
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 people with Graves' disease and a specific strain of H. pylori bacteria, removing the bacteria leads to lower levels of thyroid-stimulating hormone when no other thyroid treatment is given.
See the scientific wording
In patients with Graves’ disease and cagA-positive Helicobacter pylori infection, eradication of H. pylori was associated with decreased thyroid-stimulating hormone (TSH) levels in those not receiving definitive thyroid treatment, suggesting a potential modulatory effect on thyroid autoimmunity when the gland is intact.
A stomach bacterium injects a protein that looks like a thyroid hormone receptor, causing the immune system to attack the thyroid. This triggers chronic inflammation that spreads through the body, making the immune system more likely to target the thyroid and produce antibodies that force it to overproduce hormones.
What the research says
1 studyIn people with Graves’ disease who still have their thyroid and aren’t getting surgery or radiation, getting rid of a certain stomach bacteria (H. pylori) was linked to lower levels of a hormone (TSH) that tells the thyroid to work harder — suggesting the bacteria might be making the autoimmune problem worse.
