When someone has Graves’ disease, their thyroid hormones get too high, which tells the brain to stop making a hormone that stimulates the thyroid — so that hormone ends up being very low or even missing in blood tests.

Iodide-sensitive Graves' hyperthyroidism and the strategy for resistant or escaped patients during potassium iodide treatment.

Cohort Study
Human
2022 Aug 29

The study looks at how a medication affects thyroid levels in Graves’ disease, but it also shows that patients start with low TSH, which matches what the claim says should happen when thyroid hormones are too high.

The study shows that when someone has too much thyroid hormone in Graves’ disease, their TSH level drops, which is exactly what the claim says happens.

The study looked at a patient with Graves’ disease and found that their TSH was very low while T3 and T4 were high, which is exactly what the claim says should happen.

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.

Similar Assertions

In Graves’ disease, there might be something else besides known triggers that’s revving up the thyroid — and dexamethasone could be affecting it, since the hormone changes happen too fast to be just from antibodies.

Even in people with Graves’ disease, the thyroid still responds to its main hormone signal — TSH — by producing a key internal messenger, showing the system still works in lab tests.

Some people with an overactive thyroid get better after taking potassium iodide. If their TSH hormone goes back to normal or high, they’re much more likely to stay in remission long-term compared to those whose TSH stays too low.

Kids can have an overactive thyroid even if their TSH blood test looks normal, especially if they have a small overactive lump in the thyroid that makes hormones on its own.

Antibodies from people with Graves’ disease make thyroid cells way more active in a lab dish — like turning the volume up to 11 — by directly pushing the thyroid’s main control switch.
