Diets deficient in vitamin D can cause rickets. Today, milk is fortified with vitamin D; therefore, rickets is seldom seen in the United States. Vitamin A deficiency causes night blindness, dry eyes, and poor bone growth. Vitamin E deficiency causes hyporeflexia, retinal degeneration, and red cell hemolysis in malnourished infants. Vitamin K deficiency results in prolonged bleeding and prothrombin time, which are hemorrhagic manifestations.
