Basics of Hyperthyroidism
- Hyperthyroidism occurs when the thyroid gland produces excess hormones beyond the body's need.
- It is typically indicated by high thyroid hormones and low TSH levels in blood tests.
Diagnosing Causes of Hyperthyroidism
- After confirming hyperthyroidism, measure TSH receptor antibodies (TRAB) to diagnose Graves' disease.
- Use imaging tests only if TRAB is negative to identify other causes like toxic nodular goiter.
Thyroiditis as a Hyperthyroidism Cause
- Thyroiditis causes overactive thyroid by inflammation that releases preformed hormones, often self-limiting.
- Causes include viral infections, some medications, and iodine from radiology contrast agents.
