They presented their results in a new study at the ENDO 2025 meeting of The Endocrine Society.<\/p>\n
They focused on the small intestine (the part most active in nutrient absorption) to look for a direct connection.<\/p>\n
The research had two parts.<\/p>\n
In the first, scientists examined data from 49 patients with Hashimoto thyroiditis (the most common cause of hypothyroidism) and 323 people without the condition.<\/p>\n
All thyroid patients were already on medication, so their hormone levels appeared normal.<\/p>\n
They collected fluid samples from the small intestine during upper endoscopies and used DNA sequencing to identify which bacteria were present.<\/p>\n
In the second, they reviewed 10 years of medical records from more than one million people with hypothyroidism, comparing them to another one million without thyroid problems.<\/p>\n
This allowed them to measure the long-term risk of developing small intestinal bacterial overgrowth (SIBO).<\/p>\n
The results were striking:<\/p>\n
●\tThese gut bacteria differences existed even when thyroid hormone levels were similar, suggesting the link isn\u2019t just from hormone imbalance.<\/p>\n
●\tPeople with hypothyroidism had unique bacterial profiles, including more gram-negative bacteria and higher levels of Neisseria<\/em>, both tied to inflammation and infection.<\/p>\n ●\tIn the second analysis, those with hypothyroidism were 2.2 times more likely to develop SIBO than healthy controls.<\/p>\n ●\tPeople with Hashimoto\u2019s specifically had an even higher risk\u20142.4 times greater.\n<\/dd>\n<\/dl>\n Researchers concluded that hypothyroidism and gut bacterial imbalances are closely linked, even when thyroid levels are medically controlled.<\/p>\n This comes as no surprise to me.<\/p>\n For more than two decades, I\u2019ve helped hundreds of people to heal their hypothyroidism successfully.<\/p>\n
