Scurvy is a disease (sickness). It is caused by not eating enough vitamin C. But scurvy can be prevented. It has many symptoms. People who have scurvy get spots on their skin, especially on their legs. Their teeth may loosen and/or fall out. They may bleed from the mouth, nose, and gums (mucus membranes). A person with scurvy will look pale and feel sad (see depression). They will not be able to move easily, because their joints hurt.
