Scurvy

Definition

Scurvy is a disease resulting from a deficiency of vitamin C, also known as ascorbic acid. This micronutrient is crucial for the synthesis of collagen, a protein necessary for maintaining healthy skin, blood vessels, and connective tissues. Without sufficient vitamin C, the body cannot effectively repair tissues or maintain proper immune function, leading to various health issues.

5 Must Know Facts For Your Next Test

1. Scurvy was historically common among sailors during long sea voyages when fresh fruits and vegetables were scarce, leading to widespread vitamin C deficiency.
2. Symptoms of scurvy include fatigue, swollen and bleeding gums, joint pain, and anemia due to impaired collagen production.
3. The condition can be prevented and treated with dietary sources rich in vitamin C, such as citrus fruits, strawberries, bell peppers, and broccoli.
4. In severe cases, scurvy can lead to complications such as severe joint pain or swelling, poor wound healing, and increased susceptibility to infections.
5. Despite being rare today in developed countries, scurvy can still occur in individuals with limited access to fresh produce or in those with certain medical conditions affecting nutrient absorption.

Review Questions

• What are the primary symptoms of scurvy, and how do they relate to the role of vitamin C in the body?
  • The primary symptoms of scurvy include fatigue, swollen and bleeding gums, joint pain, and anemia. These symptoms are directly related to the role of vitamin C in collagen synthesis; without adequate vitamin C, collagen cannot be properly formed, leading to weakened connective tissues. This results in the characteristic bleeding gums and joint issues seen in individuals with scurvy.
• Discuss how scurvy was historically significant among sailors and what measures have been taken to prevent it in modern times.
  • Scurvy was historically significant among sailors during long voyages when fresh fruits and vegetables were unavailable, leading to outbreaks of this disease. To prevent scurvy today, maritime regulations often require ships to stock fresh produce or vitamin C supplements. The understanding of nutrition has evolved greatly since then, reducing the prevalence of scurvy through better dietary practices and access to a variety of foods.
• Evaluate the implications of micronutrient deficiencies like scurvy on public health, especially in vulnerable populations.
  • Micronutrient deficiencies such as scurvy have serious implications for public health, particularly among vulnerable populations like low-income communities or those with limited access to diverse foods. Scurvy can lead to increased healthcare costs due to complications from untreated symptoms and can hinder physical development in children. Addressing these deficiencies requires targeted nutrition education and improved access to nutrient-rich foods to ensure that all populations maintain adequate vitamin levels for optimal health.
