A 43-year-old female patient presents to the clinic with complaints of nervousness, racing heartbeat, anxiety, increased perspiration, heat intolerance, hyperactivity and palpitations. She states she had had the symptoms for several months but attributed the symptoms to beginning to care for her elderly mother who has Alzheimer’s Disease. She has lost 15 pounds in the last 3 months without dieting. Her past medical history is significant for rheumatoid arthritis that she has had for the last 10 years well controlled with methotrexate and prednisone. Physical exam is remarkable for periorbital edema, warm silky feeling skin, and palpable thyroid nodules in both lobes of the thyroid. Pending laboratory diagnostics, the APRN diagnoses the patient as having hyperthyroidism, also called Graves’ Disease.
Explain how the negative feedback loop controls thyroid levels.
