Some of the agents known to cause thyroiditis are antibodies (the most common cause), drugs, radiation and organisms (viruses and bacteria).
How does lithium affect thyroid?
Lithium is concentrated by the thyroid and inhibits thyroidal iodine uptake. It also inhibits iodotyrosine coupling, alters thyroglobulin structure, and inhibits thyroid hormone secretion. The latter effect is critical to the development of hypothyroidism and goiter.
What’s the difference between Graves and Hashimoto’s disease?
Hyperthyroidism in Graves’ disease is caused by thyroid-stimulating autoantibodies to the TSH receptor (TSHR), whereas hypothyroidism in Hashimoto’s thyroiditis is associated with thyroid peroxidase and thyroglobulin autoantibodies.
Is subacute thyroiditis an autoimmune disease?
This condition most likely is autoimmune in nature. Patients develop an autoimmune goiter and permanent hypothyroidism more often than they do with subacute granulomatous thyroiditis. An HLA association may be present, suggesting a genetic predisposition to subacute lymphocytic thyroiditis.
Can lithium cause thyroiditis?
Lithium has long been known to affect thyroid function. Lithium decreases production of T4 and T3 and commonly causes hypothyroidism. More rarely, lithium causes hyperthyroidism due to thyroiditis.
Can lithium cause permanent hypothyroidism?
Lithium inhibits thyroid function at various points in the thyroid axis. A large number of studies have shown that anywhere from 0; to 47% of patients on long-term lithium treatment will develop clinical hypothyroidism.
Can Hashimoto’s affect the eyes?
Eye and eyelid abnormalities are common in patients with Hashimoto’s thyroiditis. Thyroid.

How are blood tests used to diagnose thyroiditis?
How is thyroiditis diagnosed? Tests for thyroiditis may include: Thyroid function tests measure the amounts of hormones (thyroid-stimulating hormone or TSH, T3, and T4) in the blood. TSH comes from the pituitary gland and stimulates the thyroid gland to produce T4 and T3.
