What are the signs and symptoms of zinc deficiency?

    Last Updated: October 25, 2023

    Because of the widespread role of zinc in several bodily functions, the symptoms of zinc deficiency can arise in several organs — muscles, skin, and bones — and organ systems — immune, digestive, reproductive, and central nervous systems.[1] Diarrhea is a common symptom of zinc deficiency in infants, whereas poor growth and frequent infections are more common symptoms in children.[2][3][4][5] Zinc deficiency can also cause a loss of appetite and alter the sense of taste and smell.[6][4] However, these symptoms are not specific to zinc deficiency and can be caused by other conditions. Therefore, a person who suspects zinc deficiency should consult a doctor for further tests.
