Oral bleeding in scurvy. Close-up of the mouth of a patient with scurvy, showing bleeding of the gums (gingiva). Scurvy is a disease caused by a deficiency of vitamin C (ascorbic acid). It results from a diet that lacks sufficient fresh fruit and 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.
