Close-up of the mouth of a person suffering from scurvy, a disease caused by a deficiency of vitamin C (ascorbic acid), showing swollen and bleeding gums and loss of teeth. Scurvy results from a diet that is devoid of fresh fruit & vegetables. Swollen and bleeding gums are initial symptoms and may be followed by bruising of the skin (subcutaneous bleeding) and the opening of previously healed wounds. A prolonged deficiency may cause death.
