Causes of Scurvy: Vitamin C Deficiency
Scurvy is caused by a prolonged deficiency of vitamin C (ascorbic acid) in the diet, typically developing after one to three months of inadequate intake. Vitamin C is essential for collagen synthesis, and its absence leads to weakened blood vessels, poor wound healing, and other systemic symptoms 1610. The required daily intake of vitamin C is about 60 mg, which can be easily met with a single medium-sized orange, making scurvy rare in populations with access to fresh fruits and vegetables .
Key Risk Factors for Scurvy
Poor Nutrition and Dietary Habits
The most significant risk factor for scurvy is undernutrition or a diet lacking in fresh fruits and vegetables. This can result from restrictive eating habits, fad diets, or food insecurity 1234+2 MORE. Children with selective eating behaviors, especially those with autism spectrum disorder or other neuropsychiatric conditions, are at increased risk 3459. Even otherwise healthy individuals, including children, can develop scurvy if their diet is extremely limited 35.
Socioeconomic and Lifestyle Factors
Low socioeconomic status, social isolation, and economic marginalization are associated with a higher risk of scurvy due to limited access to nutritious foods 124. Alcoholism and tobacco smoking further increase the risk, as these behaviors are often linked to poor dietary choices and reduced vitamin C absorption 128.
Medical and Psychiatric Conditions
Certain medical conditions, such as chronic kidney disease, hemodialysis, gastrointestinal surgeries (like gastric bypass or sleeve gastrectomy), and severe allergies, can impair vitamin C absorption or increase its requirements, leading to deficiency 1568. Psychiatric illnesses, including severe depression and eating disorders, are also notable risk factors due to their impact on dietary intake 128.
Age and Gender
Older adults and males are more frequently affected by scurvy, possibly due to a combination of dietary habits, social factors, and comorbidities 14.
Scurvy in Modern Contexts
Despite being considered a disease of the past, scurvy is re-emerging in certain populations, particularly with rising living costs, increased rates of bariatric surgery, and persistent food insecurity 489. Clinicians are encouraged to consider scurvy in patients with unexplained fatigue, anemia, musculoskeletal pain, and mucocutaneous bleeding, especially when risk factors are present 14710.
Conclusion
Scurvy is caused by a deficiency of vitamin C and is most commonly seen in individuals with poor nutrition, restrictive diets, low socioeconomic status, certain medical or psychiatric conditions, and in those who are older or male. Awareness of these risk factors is crucial for timely diagnosis and treatment, as scurvy remains a preventable and reversible condition when recognized early 1234+6 MORE.
