Study Notes
Thyroid Replacement Therapy
- Thyroid replacement is used to treat hypothyroidism, a condition where the thyroid gland produces insufficient thyroid hormones, hindering the body's metabolic functions.
- Causes include autoimmune diseases (e.g., Hashimoto's thyroiditis), surgical removal, destruction by radiation, and poorly functioning thyroid glands.
- Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism.
- Levothyroxine is an isomer of thyroxine (T4) mimicking T4's action by stimulating T4 receptors in the body and effectively replacing the client's thyroid hormone.
- Side effects of levothyroxine overdose mimic extreme hyperthyroidism.
- Symptoms indicating potential toxicity include chest pain, hypertension, and tachycardia.
- Palpitations are a sign of possible toxicity, indicating potential arrhythmias including atrial fibrillation.
