Postoperative hypothyroidism

Last edited: 4/10/2026

Overview

Postoperative hypothyroidism can occur after thyroid surgery, particularly in the context of thyroid cancer treatment. Management often involves thyroid-stimulating hormone (TSH) suppression therapy.

Diagnosis

Management

  • TSH suppression therapy is used in patients after thyroid cancer surgery 1.
  • Special Populations

    Key Recommendations

  • TSH suppression therapy after thyroid cancer surgery increases the risk of atrial fibrillation 1.
  • TSH suppression therapy after thyroid cancer surgery is associated with higher heart rate, systolic blood pressure, and diastolic blood pressure compared to controls 1.
  • TSH suppression therapy after thyroid cancer surgery does not appear to significantly affect ejection fraction or left ventricular end-diastolic diameter 1.
