Selenium Deficiency

Selenium deficiency, while not common, does occur in surgical patients, particularly those patients on TPN (total parenteral nutrition.)

Selenium is essential for most tissues in the body and acts as a cofactor in peroxidase enzyme reactions.

Signs and symptoms of selenium deficiency include cardiomyopathy (can be fatal), discoloration of the nails, hyperpigmentation of the skin, vision changes, and loss of neurological function.
