The Claim
Long-lasting Helicobacter pylori infection, defined by histological evidence of gastric atrophy, metaplasia, or dysplasia, is associated with a 34% higher odds of autoimmune thyroid disease in adult women from Northern Sardinia, independent of age, body mass index, and smoking status.
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.
Adult women from Northern Sardinia with long-lasting Helicobacter pylori infection, confirmed by gastric tissue changes, have a 34% higher likelihood of developing autoimmune thyroid disease compared to those without such infection, after accounting for age, body mass index, and smoking.
See the scientific wording
Long-lasting Helicobacter pylori infection, defined by histological evidence of gastric atrophy, metaplasia, or dysplasia, is associated with a 34% higher odds of autoimmune thyroid disease in adult women from Northern Sardinia, independent of age, body mass index, and smoking status, suggesting a potential role of chronic gastric inflammation in autoimmune thyroid pathogenesis.
A long-lasting stomach infection damages the stomach lining and releases proteins that look similar to proteins in the thyroid. The immune system attacks these stomach proteins but also mistakes thyroid proteins for the same threat, leading to immune cells and antibodies attacking the thyroid. At the same time, the infection changes how the immune system behaves, making it less able to stop these mistaken attacks.
What the research says
1 studyStudy: Association of Helicobacter pylori Infection with Autoimmune Thyroid Disease in the Female Sex
Women in Northern Sardinia who have had a long-term stomach infection caused by H. pylori, shown by tissue damage, are about 34% more likely to have an autoimmune thyroid disease like Hashimoto’s, even when you account for their age, weight, and smoking habits.
