Scurvy is the disease you get if you don't get enough vitamin C. Historically associated with sailors on long voyages, this nutritional deficiency disease is still a concern today for individuals with poor diets or malabsorption issues. Vitamin C, or ascorbic acid, is an essential nutrient that humans cannot produce on their own and must be obtained through food. It plays a critical role in the synthesis of collagen, a structural protein necessary for healthy skin, blood vessels, bones, and gums. When collagen production is compromised, it leads to the widespread and varied symptoms of scurvy.
The Role of Vitamin C and the Progression of Scurvy
Vitamin C is vital for several bodily functions, including boosting the immune system, absorbing iron, and acting as a powerful antioxidant to protect against cell damage from free radicals. A deficiency often begins with subtle, non-specific symptoms that can be easy to overlook, gradually worsening over several months if the vitamin C intake is not addressed.
Early Symptoms
Initially, a person with a low vitamin C intake may experience fatigue, weakness, irritability, and muscle or joint aches. These symptoms are often vague and can be mistaken for other health problems, delaying an accurate diagnosis.
Advanced Signs of Deficiency
As the deficiency becomes more severe and develops into scurvy, more characteristic signs appear:
- Gum disease: Gums can become swollen, purple, spongy, and bleed easily. Eventually, teeth may loosen or fall out.
- Skin changes: The skin may become dry and rough, with small red or blue spots (petechiae) appearing around hair follicles, particularly on the legs. Bruising occurs more easily.
- Hair abnormalities: Hair can become dry, brittle, and develop a distinctive coiled or 'corkscrew' shape.
- Wound healing: The ability to heal wounds is severely impaired, and old wounds may reopen.
- Anemia: A deficiency in vitamin C can contribute to anemia due to impaired iron absorption and blood loss from internal bleeding.
- Musculoskeletal pain: Joint and bone pain, sometimes severe, can result from hemorrhages into the joints or under the periosteum, the membrane covering bones.
Causes and Risk Factors for Vitamin C Deficiency
While scurvy is rare in many developed countries, certain groups are at a higher risk due to dietary habits or underlying health conditions. The primary cause is simply not consuming enough fresh fruits and vegetables.

Diagnosis and Treatment
Diagnosing scurvy typically involves a physical examination and review of symptoms, alongside a detailed dietary history. Blood tests can also measure vitamin C levels to confirm a diagnosis. The treatment is straightforward and highly effective: vitamin C supplementation.

Common Symptoms: Vitamin C Deficiency vs. Scurvy
While scurvy is the severe form of a vitamin C deficiency, symptoms can vary depending on the severity. The following table compares common manifestations, with more details available on {Link: Medscape https://emedicine.medscape.com/article/125350-overview}:
| Symptom | Mild Vitamin C Deficiency | Severe Vitamin C Deficiency (Scurvy) |
|---|---|---|
| Energy Level | Feeling tired, weak, and irritable. | Profound fatigue and lethargy. |
| Musculoskeletal | Vague muscle and joint aches. | Severe bone and joint pain, potential for hemorrhages. |
| Skin | Easy bruising, slow wound healing. | Petechiae (small red spots), rough, dry skin, and reopening of healed wounds. |
| Oral Health | Mild bleeding gums, gingivitis. | Swollen, purple, spongy gums; teeth may loosen or fall out. |
| Hair | Dry, splitting hair. | Dry, brittle, and characteristically coiled ('corkscrew') hair. |
Conclusion
Scurvy, the disease resulting from a severe lack of vitamin C, is a reminder of the critical importance of proper nutrition. While largely preventable with a diet rich in fruits and vegetables, it can still affect vulnerable populations today. The key to combating this disease lies in early recognition of its diverse symptoms and swift intervention with vitamin C supplementation. A balanced diet provides sufficient vitamin C for most people, but specific risk factors require careful attention to nutritional intake. Addressing the underlying causes is essential to prevent recurrence and ensure long-term health.

James Lind and the History of Scurvy
James Lind, a British naval surgeon, conducted a groundbreaking controlled clinical experiment in 1747 demonstrating that citrus fruits could cure scurvy among sailors. This was a major step toward understanding nutritional deficiencies. The adoption of citrus provisions by the British Royal Navy improved sailor health and influenced naval battles.
