Graves’ disease patients have increased sensitivity to adrenaline, and along with increased thyroid hormone in their blood, this results in rapid heart beat, sweating, shakiness, anxiety, increased appetite, loss of weight, and intolerance to heat. β-blockers help to alleviate these symptoms when given along with antithyroid drugs or radioactive iodine in an effort to make the patient more comfortable while awaiting return to normal thyroid function.
