scurvy
Scurvy is a disease caused by a deficiency of vitamin C, which is essential for the production of collagen, a protein important for skin, blood vessels, and connective tissues. Without enough vitamin C, symptoms can include fatigue, swollen gums, joint pain, and bruising. Historically, scurvy affected sailors on long voyages who lacked fresh fruits and vegetables. It is now rare in developed countries but can still occur, particularly in those with poor diets or malabsorption issues. Prevention and treatment involve increasing vitamin C intake through food or supplements, with citrus fruits being a well-known source.
