In Graves' disease, the body's immune system accidentally attacks the thyroid by making antibodies that turn it on too much, causing it to overproduce hormones and leading to a condition called hyperthyroidism.

Targeting TSH and IGF-1 Receptors to Treat Thyroid Eye Disease
The study explains that Graves’ disease happens when the immune system makes antibodies that turn on the thyroid too much by targeting TSH receptors, which matches the claim.
This paper shows that if you block the thyroid’s switch, the immune antibodies can’t turn it on—proving they’re the cause of the overactivity.

Hypothyroidism with Graves' disease.
The study looks at people with Graves’ disease who don’t have an overactive thyroid, even though the disease usually causes it. This goes against the idea that Graves’ always leads to too much thyroid hormone.
This paper describes a family with inherited overactive thyroid that isn’t caused by immune attacks, showing not all such cases are autoimmune like Graves’ disease.
This case shows someone with eye symptoms of Graves’ disease but no overactive thyroid and no detectable antibodies, suggesting the disease can happen even without the usual immune markers.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
