The Claim
Approximately 11% of patients with Graves' disease experience treatment failure after a single 555 MBq radioactive iodine dose, and 60% of these treatment failures are successfully managed with a second radioactive iodine dose.
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.
About 11 out of 100 people with Graves' disease do not respond to one dose of 555 MBq radioactive iodine, but 6 out of 10 of those people respond to a second dose of radioactive iodine.
See the scientific wording
Approximately 11% of patients with Graves' disease experience treatment failure after a single 555 MBq radioactive iodine (RAI) dose, but most of these cases (60%) can be successfully managed with a second RAI treatment.
Radioactive iodine is absorbed by thyroid cells, but some cells take up less iodine and survive the first treatment. These surviving cells continue producing thyroid hormone, causing the disease to return. A second dose of radioactive iodine kills these remaining cells, curing the disease.
What the research says
1 studyAbout 1 in 10 people treated with one dose of radioactive iodine for Graves' disease don’t get fully better, but most of those people (6 in 10) can be cured with a second dose — and this study proves it.
