Euthyroid

Euthyroid

The state of having normal thyroid gland function. Found in 40-70% of hospitalised elderly patients. Due to chronic/severe illness or surgery, there is a marked decrease in the liver conversion of T4 to T3Clarifyme|date=September 2008. This is because of the reduced activity of Type 1 deiodinase. The condition is characterised by a low plasma T3 despite a normally functioning thyroid.

Examples of a nonfunctioning thyroid gland may be hypothyroidism or hyperthyroidism as opposed to euthyroidism, a functioning thyroid.
