What are three signs and symptoms of scurvy?
Scurvy arises when the body lacks sufficient vitamin C, a key nutrient for synthesizing collagen. Collagen is a crucial protein that maintains the structure and integrity of connective tissues, blood vessels, skin, bones, and gums. When collagen production is compromised, the body's tissues start to break down, leading to a cascade of observable symptoms. While the disease can manifest in many ways, three of the most classic and pronounced signs are related to bleeding gums, easy bruising, and profound fatigue.
1. Swollen, Spongy, and Bleeding Gums
One of the most widely recognized hallmarks of scurvy is the deterioration of gum health. The gums, which are a type of connective tissue, rely heavily on collagen for their structural integrity. Without adequate vitamin C, this collagen synthesis is severely impaired, causing the gums to become swollen, purple, and spongy. They are prone to bleeding from even the slightest irritation, such as gentle brushing or light pressure. In advanced cases, this gingival tissue can become so compromised that the teeth may loosen or even fall out.
2. Easy Bruising and Skin Hemorrhages
Another prominent sign of scurvy is the easy formation of bruises and small, pinpoint hemorrhages under the skin. This is a direct consequence of fragile blood vessels. The walls of blood vessels, like other connective tissues, are supported by collagen. A deficiency of vitamin C weakens these walls, making them susceptible to rupture from minor impacts or even spontaneously.
- Petechiae: These are small, red or blue, pinpoint spots that appear on the skin, often around hair follicles, particularly on the lower legs and feet.
- Ecchymoses: Larger areas of bleeding under the skin lead to easy and widespread bruising.
- Perifollicular Hemorrhage: This occurs when blood leaks from capillaries surrounding the hair follicles. Along with coiled, brittle hair (often described as corkscrew hairs), this is a very specific dermatological sign of scurvy.
3. Profound Fatigue and Weakness
Persistent and debilitating fatigue is a common early symptom of scurvy, often accompanied by general weakness and lethargy. The link between vitamin C and fatigue is twofold. First, vitamin C is necessary for the synthesis of carnitine, a molecule essential for transporting fatty acids into the mitochondria for energy production. A lack of carnitine can lead to impaired energy metabolism, causing weakness and lethargy. Second, vitamin C aids in the absorption of iron, and its deficiency can lead to anemia, a known cause of fatigue.
Other Important Symptoms of Scurvy
Beyond the primary triad, scurvy can present with a variety of other symptoms as the deficiency progresses:
- Joint and Muscle Pain: This can result from bleeding into the muscles or around the joints, causing excruciating pain and sometimes a reluctance to move.
- Poor Wound Healing: Since collagen is critical for tissue repair, a lack of vitamin C significantly delays wound healing. Previously healed wounds may even reopen.
- Mood Changes: Individuals may experience irritability, mood swings, or depression.
- Anemia: Iron deficiency anemia is common due to impaired iron absorption and internal bleeding.
The Pathophysiology Behind Scurvy
As mentioned, the root cause of these symptoms is the impaired synthesis of collagen. Ascorbic acid, or vitamin C ($$C_6H_8O_6$$), is a required cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase. These enzymes add hydroxyl groups to the amino acids proline and lysine in the collagen precursor molecule. This hydroxylation is critical for forming the stable, triple-helix structure of mature collagen. Without stable collagen, connective tissues throughout the body become weak and fragile, leading to the bleeding and tissue breakdown seen in scurvy.
Comparison of Early vs. Advanced Scurvy
| Feature | Early Scurvy (1-3 months of deficiency) | Advanced Scurvy (3+ months of deficiency) |
|---|---|---|
| Energy Level | Vague fatigue, irritability, weakness | Profound lethargy, depression, severe weakness |
| Skin | Easy bruising, petechiae, perifollicular hemorrhages | Widespread ecchymoses, follicular hyperkeratosis, corkscrew hairs |
| Oral Health | Mild gingivitis, soreness | Swollen, purple, spongy, and severely bleeding gums |
| Teeth | Generally stable, but can become sore | Loosened teeth, potential for tooth loss |
| Wound Healing | Delayed | Poor or non-existent healing, reopening of old wounds |
| Musculoskeletal | Vague aches, joint pain | Severe bone pain, joint effusions, hemarthrosis |
Prevention and Treatment through Nutrition Diet
Fortunately, scurvy is a highly treatable and preventable disease. Treatment involves addressing the vitamin C deficiency, with symptoms often improving within 24-48 hours. The primary prevention strategy is incorporating a nutrition diet rich in vitamin C.
Excellent sources of vitamin C include:
- Citrus Fruits: Oranges, lemons, limes, and grapefruits.
- Berries: Strawberries, blackcurrants, and raspberries.
- Vegetables: Bell peppers (especially red and green), broccoli, Brussels sprouts, spinach, and tomatoes.
- Other: Kiwi, papaya, and cantaloupe.
Cooking can destroy a significant portion of a food's vitamin C content, so consuming fresh, raw fruits and vegetables is the most effective way to prevent deficiency. Supplements are a viable option for those unable to meet their daily needs through diet alone. It is important to consult a healthcare professional regarding appropriate supplementation.

Conclusion
While rare in modern developed societies, scurvy remains a threat to vulnerable populations with poor dietary intake. The classic triad of swollen, bleeding gums, easy bruising, and fatigue are critical indicators of a severe vitamin C deficiency. Recognizing these symptoms allows for swift diagnosis and simple, effective treatment by addressing the vitamin C deficiency, reversing the condition and preventing more serious complications. A balanced, nutrient-rich diet, centered on fresh fruits and vegetables, is the best defense against this easily preventable disease.
