Subclinical Hyperthyroidism (SCH)

  • Subclinical Hyperthyoidism or SCH is a very mild form of hyperthyroidism, wherein the patients experience low TSH levels even when their thyroxine (T3) and triodothyronine (T4) levels are normal.
  • This condition is different from hyperthyroidism, with about 1-2%of the population suffering from the condition and is higher in regions where people suffer from iodine deficiency.

Causes of SCH

  • SCH can be caused due to exogenous and endogenous thyroid hormone excess. Exogenous SCH is generally caused by the excessive consumption of thyroid hormone either intentionally or unintentionally by the patients.
  • This might include the excessive use of levothyroxine (LT4) by patients suffering from thyroid cancer, to suppress the excessive TSH levels.
  • Endogenous SCH might be caused by toxic multinodular goiter, solitary autonomously functioning nodule, Graves’ disease and thyroiditis.


Symptoms And Diagnosis Of SCH

  • Most patients suffering from SCH are asymptomatic, which means that they do not show any symptoms of the ailment.
  • In the rare case that the symptoms might become evident, they are quite similar to the ones seen in patients suffering from overt hyperthyroidism.
  • However, in such cases the symptoms are much milder and might include fatigue, palpitation, anxiety, heat intolerance, weight loss and loose stools etc.

Evaluation And Treatment Options For SCH

A systematic review, excluding the other causes of subnormal serum TSH concentration, offers the following suggestions about the evaluation and treatment of SCH.

  • Retesting Of Patients: Patients having atrial fibrillation, cardiac disease, or a TSH <0.1 mIU/L are advised to undergo a retest after 2-4 weeks while other patents can be retested after 3 months.
  • Patients With TSH <0.1 mIU/L: Such patients are advised a radioactive iodine uptake scan and the treatment of the disease should be based on the results of the test as follows.
    • Patients aged below 60 years and having mild TSH suppression ranging between 0.1–0.45 mIU/L, should follow up the low radioactive iodine uptake with serial TSH testing after a gap of 3-12 months. However, the thyroid suppression might be recommended in patients suffering from cardiac disease, decreased BMD, or symptoms suggestive of hyperthyroidism.
    • Patients above the age of 60 years and having TSH less than 0.1 mIU/L, should be prescribed antithyroid treatment to decrease the risk of complications related to cardiac and bone loss.
    • The dosage of patients receiving thyroid replacement therapy should be adjusted so that a normal serum TSH concentration is maintained. However, a lower TSH may be unavoidable for prevention or reduction of goiter growth and thyroid cancer. In such cases the least level of suppression required can help minimize the adverse effects of treatment.
