Quick Summary

Subclinical hypothyroidism is a condition characterized by elevated serum thyrotropin (TSH) concentrations with normal serum concentrations of thyroxine and triiodothyronine. This means that while the pituitary gland is signaling the thyroid to produce more hormones, the thyroid is still functioning adequately to maintain normal levels of circulating thyroid hormones. Consequently, individuals with subclinical hypothyroidism typically experience few or no symptoms.123

The diagnosis is made through thyroid function tests, specifically by measuring serum thyrotropin and thyroxine levels. If left untreated, subclinical hypothyroidism can progress to overt hypothyroidism, where symptoms become apparent.31
