Which of the following is caused by severe Vitamin C deficiency?

Vitamin C deficiency is called Scurvy. Vitamin C acts as an antioxidant, boost immune health, needed to synthesize collagen and many more. Scurvy has been known since ancient Greek and Egyptian times. It is often associated with sailors in the 15th to 18th centuries, when long sea voyages made it hard to get a steady supply of fresh produce. It also occurred during the Irish potato famine in 1845 and the American Civil War. The most recent outbreak was in Afghanistan in 2002, following war and a draught.

Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens, there can be poor wound healing, personality changes, and finally death from infection or bleeding. Other risk factors include intestinal malabsorption and dialysis.

The human body cannot manufacture vitamin C, which must be taken from external sources, especially fruits and vegetables or fortified foods. Vegetables and fruits that contain vitamin C are Oranges, Strawberry, Tomato juice, Kiwi fruit, Cauliflower, Cabbage, Spinach, Sweet red pepper and so on.

Scurvy in infants is rare because breast milk usually supplies enough vitamin C and infant formulas are fortified with the vitamin. Scurvy is rare in the United States but may occur in alcohlics and older people who are malnourished.
