What is subclinical hypothyroidism?

Subclinical hypothyroidism means that blood tests indicate hypothyroidism by the presence of high levels of TSH (thyroid-stimulated hormone). Other than test results, there are no obvious symptoms of the disorder. In this case, doctors may choose to prescribe synthetic thyroid hormone medicine or they may simply choose to monitor the condition to see if TSH levels go higher or if symptoms develop.

Subclinical hypothyroidism is when the body is not making sufficient thyroid hormone or the body (or parts of the body) is not recognizing and accepting the hormone. A person can exhibit both physical and mental symptoms of Low thyroid hormone, but all blood test will be within normal ranges (depending on the test diagnostics used). A doctor who suspects a low functioning thyroid may or may not treat the condition depending on office procedure, education and experience. Typically a doctor will monitor blood hormone levels (TSH, T4, Free T4, T3, Free T3) and self-reported symptoms of the patient over a year time period to see if there is an observable a pattern. Hashimoto’s can be the result from untreated or unrecognized low functioning thyroid.
