The Progression of Scurvy
Scurvy is caused by a severe, prolonged deficiency of vitamin C (ascorbic acid). Since humans cannot produce vitamin C, it must come from the diet. A dramatic drop in intake depletes the body's stores over weeks to months, impairing collagen synthesis. Collagen is vital for the structure of skin, blood vessels, bone, and connective tissues.
Phase 1: Early Onset (4 to 12 weeks)
The initial symptoms of scurvy can be subtle and non-specific.
- Fatigue: A common early sign is persistent tiredness.
- Weakness and Irritability: Muscle weakness and mood changes like irritability may occur.
- Joint Pain: Aches in the legs and arms are frequent.
- Loss of Appetite: A reduced desire to eat often accompanies general malaise.
Phase 2: Progressive Symptoms (1 to 3 months)
As the deficiency worsens, more specific symptoms appear due to weakened connective tissue.
- Bruising and Bleeding: Easy bruising, pinpoint skin bleeding (petechiae), and joint hemorrhages occur due to fragile capillaries.
- Gum Disease: Gums become swollen, spongy, purple, and bleed easily. Teeth may loosen.
- Poor Wound Healing: New wounds heal poorly, and old scars may reopen.
- Skin Changes: Skin can be rough and dry. "Corkscrew hairs" may develop.
Phase 3: Advanced Stages and Complications
Untreated scurvy can lead to serious complications. These can include severe anemia, nerve damage, fever, and in extreme cases, convulsions or death due to extensive bleeding or infection.
Factors Influencing Scurvy Onset
The 1-3 month timeframe is a general guide, but onset speed varies based on individual factors like initial vitamin C stores, overall diet, the presence of risk factors such as smoking or alcoholism, and age.
Symptom Comparison: Early vs. Late Scurvy
| Feature | Early Scurvy (Weeks 4-12) | Advanced Scurvy (Months 1-3+) | 
|---|---|---|
| Energy Level | Fatigue, weakness | Profound weakness | 
| Mood | Irritability, depression | Significant mood changes | 
| Musculoskeletal | Aches | Severe pain, swelling, hemorrhage | 
| Skin | Easy bruising, petechiae, dry | Widespread bruising, corkscrew hairs | 
| Gums and Teeth | Mild inflammation | Swollen, bleeding, purple, loose teeth | 
| Wound Healing | Reduced rate | Impaired healing, old scars reopen | 
| Anemia | May develop | Often severe | 
Treatment and Prevention
Scurvy is treatable with vitamin C supplements and dietary changes. Symptoms improve within 24-48 hours, resolving in weeks to months. Prevention involves a diet rich in vitamin C. Good sources include citrus fruits, berries, peppers, broccoli, potatoes, tomatoes, and kiwi.
Conclusion
Scurvy typically develops over 1-3 months of severe vitamin C deficiency, progressing from general weakness to specific signs of collagen breakdown. The timeline varies, but early recognition and vitamin C supplementation lead to rapid improvement. A diet rich in vitamin C is the best prevention.
