The Claim
In women with levothyroxine-resistant hypothyroidism, Helicobacter pylori infection is associated with significantly elevated TSH and reduced free T4 and free T3 levels compared to healthy individuals.
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.
Women with levothyroxine-resistant hypothyroidism who have Helicobacter pylori infection have higher TSH levels and lower free T4 and free T3 levels than women without the infection.
See the scientific wording
In women with levothyroxine-resistant hypothyroidism, Helicobacter pylori infection is associated with significantly elevated TSH and reduced free T4 and free T3 levels compared to healthy individuals, suggesting a potential role for gastric infection in impairing thyroid hormone regulation.
A stomach infection causes low acid levels, which stops thyroid medicine from dissolving properly, so the body cannot absorb enough of it. The infection also tricks the immune system into attacking the thyroid gland, which destroys hormone-producing cells. Together, this lowers active thyroid hormone levels and makes the brain signal for more hormone production.
What the research says
1 studyWomen with thyroid problems that don’t improve with medicine had worse hormone levels when they also had a stomach infection called H. pylori. When doctors treated the infection, their thyroid levels got better, suggesting the infection was making their thyroid problem worse.
