Factitious hyperthyroidism

  • Alternative Names

    Factitious thyrotoxicosis; thyrotoxicosis factitia; thyrotoxicosis medicamentosa


    You must stop taking thyroid hormone. If it is medically necessary, the dose must be reduced.

    You should be re-evaluated in 2 - 4 weeks to be sure that the signs and symptoms of hyperthyroidism are gone. This also helps to confirm the diagnosis.

    People with Munchausen syndrome will need psychiatric treatment and follow-up.

    Expectations (prognosis)

    Factitious hyperthyroidism will clear up on its own when you stop taking or lower the dose of thyroid hormone.


    When factitious hyperthyroidism lasts a long time, patients are at risk for the same complications of untreated or improperly treated hyperthyroidism caused by the thyroid gland.

    These complications include:

    • Atrial fibrillation
    • Chest pain (angina)
    • Heart attack
    • Irregular heart rhythm
    • Loss of bone mass (if severe, osteoporosis)
    • Weight loss
