 | | The signs and symptoms of zinc deficiency include anorexia, growth retardation, delayed sexual maturation, hypogonadism and hypospermia, alopecia, immune disorders, dermatitis, night blindness, impaired taste (hypogeusia), and impaired wound healing. |
 | | Zinc deficiency develops in some patients with cirrhosis because the ability to retain zinc is lost. |
 | | Biochemical signs associated with zinc deficiency include decreased levels of plasma zinc (< 70 µg/dL [< 10.7 µmol/L]), alkaline phosphatase, alcohol dehydrogenase in the retina (which accounts for night blindness), and plasma testosterone as well as impaired T-lymphocyte function, decreased collagen synthesis (resulting in poor wound healing), and decreased RNA polymerase activity in several tissues. |
