What Is Scurvy?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Scurvy is a disease resulting from a deficiency of vitamin C (ascorbic acid), which is essential for various bodily functions, including collagen synthesis and antioxidant protection. This article explores the causes, symptoms, and physiological impacts of scurvy, drawing on recent research findings.

Causes of Scurvy

Scurvy is primarily caused by insufficient intake of vitamin C. Humans, unlike some animals, cannot synthesize vitamin C endogenously and must obtain it through their diet. Ascorbic acid is crucial for the synthesis of collagen, a protein that helps maintain the integrity of skin, blood vessels, bones, and connective tissues. A prolonged deficiency in vitamin C disrupts these processes, leading to the symptoms and complications associated with scurvy1 2.

Symptoms of Scurvy

The symptoms of scurvy can manifest after a few weeks of severe vitamin C deficiency. Early signs include fatigue, malaise, and inflammation of the gums. As the deficiency progresses, more severe symptoms can develop, such as:

• Bleeding Gums and Tooth Loss: The weakening of collagen in the gums leads to bleeding and, eventually, tooth loss.
• Skin Issues: Petechiae (small red spots caused by bleeding under the skin), bruising, and slow wound healing are common due to impaired collagen synthesis.
• Joint Pain and Swelling: Collagen is a critical component of cartilage, and its deficiency can lead to joint pain and swelling.
• Anemia: Vitamin C enhances iron absorption, and its deficiency can contribute to anemia.

Physiological Impacts of Scurvy

Endoplasmic Reticulum Stress and Apoptosis

Recent studies have shown that scurvy can lead to significant cellular stress and damage. For instance, a study on guinea pigs demonstrated that ascorbate deficiency causes endoplasmic reticulum (ER) stress and apoptosis in liver cells. The lack of ascorbate disrupts oxidative protein folding in the ER, leading to an accumulation of misfolded proteins, ER stress, and eventually cell death through apoptosis1. This suggests that insufficient protein processing is a key factor in the pathology of scurvy.

Bone Density and Collagen Synthesis

Scurvy also severely impacts bone health. Research using a guinea pig model revealed that severe ascorbic acid deficiency results in decreased collagen synthesis and bone density. The study found that scorbutic animals exhibited significantly lower bone mineral density and content, as well as reduced collagen synthesis in articular cartilage and tendons. These changes were not observed in animals that were pair-fed but received adequate ascorbic acid, indicating that the effects were specifically due to vitamin C deficiency rather than reduced food intake2.

Conclusion

Scurvy is a serious condition caused by a deficiency in vitamin C, leading to a range of symptoms from gum disease to severe physiological impacts like ER stress and decreased bone density. Ensuring adequate intake of vitamin C through diet or supplementation is crucial for preventing this disease and maintaining overall health.
