Scurvy is a nutritional deficiency disorder caused by inadequate intake or absorption of vitamin C (ascorbic acid).
Vitamin C is an essential, water-soluble micronutrient that humans cannot synthesize endogenously and must obtain through dietary sources such as fruits and vegetables. Scurvy results from prolonged vitamin C deficiency, leading to impaired collagen synthesis, capillary fragility, defective bone formation, anemia, and immune dysfunction.
Historically associated with maritime exploration, scurvy is often considered a disease of the past. However, modern pediatric scurvy continues to be reported worldwide, particularly among children with restrictive diets, neurodevelopmental disorders, food insecurity, or malabsorption syndromes. A research stated in The Lancet, Pediatrics, and BMJ Case emphasize that scurvy remains clinically relevant and frequently underdiagnosed due to its nonspecific early presentation.
Global Epidemiology of Scurvy in Children
Although scurvy is rare in high-income countries, pediatric cases are increasingly reported across both developed and developing regions. Epidemiological data from The Lancet Global Health and Nutrients (MDPI) indicate that scurvy disproportionately affects children in contexts of nutritional inadequacy rather than absolute food scarcity.
Global Patterns and Risk Groups
- Low- and middle-income countries: Scurvy persists where diets lack fresh fruits and vegetables due to poverty, food insecurity, or seasonal availability.
- High-income countries: Cases are increasingly reported among children with:
- Autism spectrum disorder
- Avoidant/restrictive food intake disorder (ARFID)
- Severe picky eating
- Chronic illness or malabsorption
A systematic review published in Pediatrics found that most pediatric scurvy cases occur between 2-10 years of age, often after several months of vitamin C deficient diets. The true prevalence is likely underestimated due to misdiagnosis as infections, rheumatologic disorders, or malignancy.
How Does Scurvy Affect Children?
Vitamin C is essential for multiple biological processes critical to growth and development. In children, deficiency leads to multisystem involvement, often with predominant musculoskeletal manifestations.
Pathophysiological Mechanisms
Vitamin C functions as a cofactor for:
- Prolyl and lysyl hydroxylase, enzymes required for collagen maturation
- Iron absorption, preventing iron-deficiency anemia
- Antioxidant defense, reducing oxidative tissue damage
- Immune cell function, supporting innate and adaptive immunity
In deficiency states, defective collagen synthesis causes fragile blood vessels, impaired bone matrix formation, delayed wound healing, and gum pathology. Pediatric bones, which are actively growing, are particularly vulnerable, explaining the prominence of skeletal symptoms.
Symptoms of Scurvy in Children
Scurvy often presents insidiously, with early symptoms that are nonspecific and easily overlooked. As deficiency progresses, characteristic clinical features emerge.
1. General & Systemic Symptoms of Scurvy
Poor Appetite and Weight Loss
Poor appetite is one of the earliest manifestations of scurvy, particularly in children. Vitamin C deficiency disrupts normal metabolic and inflammatory regulation, leading to anorexia and a reduction in caloric intake. Chronic deficiency results in weight loss, failure to thrive, and growth retardation. Studies published in The American Journal of Clinical Nutrition reported that prolonged low plasma ascorbate levels impair energy metabolism and nutrient utilization, contributing to malnutrition even when calorie intake is adequate.
Irritability and Pain
Irritability is a prominent early symptom, especially in infants and young children. It reflects underlying musculoskeletal pain caused by subperiosteal hemorrhages and defective bone matrix formation. Children may appear withdrawn, inconsolable, or unusually aggressive. According to the BMJ Case Reports, Pain is often disproportionate to physical findings and may be misattributed to behavioral or psychological causes.
Fever
Low-grade fever may occur in scurvy due to systemic inflammation and impaired immune regulation. Vitamin C plays a critical role in immune cell function; deficiency leads to dysregulated cytokine release, producing inflammatory responses that mimic infection. This frequently results in misdiagnosis and unnecessary antibiotic use. These facts reported in the journal of Lancet Child & Adolescent Health.
Anemia
Anemia in scurvy is multifactorial. Vitamin C enhances non-heme iron absorption; deficiency reduces iron bioavailability and contributes to iron-deficiency anemia. Additionally, chronic inflammation and occult bleeding from fragile capillaries worsen anemia. A study published in the journal of Haematologica reported cases describe normocytic or microcytic anemia with elevated inflammatory markers.
2. Musculoskeletal Symptoms (Very Common)
Limping or Refusal to Walk
Limping or complete refusal to walk is a hallmark feature of pediatric scurvy and often prompts orthopedic evaluation. Pain arises from subperiosteal hemorrhages, microfractures, and defective osteoid formation. The lower limbs are most commonly affected due to weight-bearing stress. Radiological findings may mimic osteomyelitis or malignancy, contributing to delayed diagnosis according to the study reported in Journal of Pediatric Orthopaedics.
Painful Swellings
Painful soft-tissue swellings occur due to bleeding beneath the periosteum, particularly around the knees, ankles, and wrists. These swellings are tender, non-inflammatory in appearance, and may be mistaken for abscesses or tumors. Ultrasound and MRI frequently reveal hemorrhagic collections according to the study reported in Journal of Radiographics.
Bone Pain
Bone pain results from impaired collagen synthesis within the bone matrix, leading to structural weakness and microfractures. Pain is often severe, persistent, and exacerbated by movement. Children may adopt protective postures or avoid physical activity altogether.
3. Skin and Hair Symptoms
Easy Bruising and Petechiae
Capillary fragility due to defective collagen leads to spontaneous bruising and petechial hemorrhages, particularly on the lower extremities. Minor trauma can cause extensive ecchymoses. These findings are often mistaken for coagulation disorders or non-accidental injury as stated by research published in the journal of Clinical Dermatology.
Rough, Dry Skin
Vitamin C deficiency disrupts normal skin structure and keratinization, resulting in dry, rough, and hyperkeratotic skin. Follicular hyperkeratosis is commonly observed, especially on the arms and thighs.
Corkscrew Hairs
Corkscrew or coiled hairs are a classic dermatological sign of scurvy. They result from abnormal keratin formation and weakened hair shafts. Perifollicular hemorrhage may accompany this finding, making it highly suggestive of vitamin C deficiency as per British Journal of Dermatology.
4. Oral and Dental Symptoms
Swollen, Bleeding Gums
Gingival swelling, bleeding, and pain occur due to breakdown of periodontal collagen and increased bacterial invasion. Gums appear spongy, erythematous, and prone to spontaneous bleeding. According to the study reported in the Journal of Clinical Periodontology, these symptoms are more pronounced in children with erupted teeth.
Loose Teeth
Advanced scurvy leads to weakening of the periodontal ligament and alveolar bone resorption, causing tooth mobility and, in severe cases, tooth loss. These changes significantly impair nutrition and oral health.
5. Healing Issues
Slow Wound Healing
Vitamin C is essential for collagen deposition during tissue repair. Deficiency leads to delayed wound healing, poor scar formation, and increased risk of wound dehiscence. Even minor cuts may take weeks to heal. This impaired regenerative capacity is a defining feature of scurvy and rapidly reverses with vitamin C supplementation. These data are reported in the journal of Wound Repair and Regeneration.
How Is Scurvy Diagnosed?
Diagnosis of scurvy is primarily clinical, supported by dietary history and laboratory findings.
Diagnostic Approach
- Dietary assessment: Lack of vitamin C–rich foods for ≥1–3 months
- Clinical features: Musculoskeletal pain, bleeding gums, bruising
- Laboratory findings:
- Low plasma ascorbic acid (<0.2 mg/dL)
- Anemia, elevated inflammatory markers
- Imaging:
- X-rays may show metaphyseal changes such as:
- Frankel line
- Pelkan spurs
- Trümmerfeld zone
- X-rays may show metaphyseal changes such as:
Rapid symptom improvement after vitamin C supplementation is considered diagnostic confirmation, as noted in The Lancet Child & Adolescent Health.
How Can Scurvy Be Prevented?
Scurvy is entirely preventable through adequate dietary vitamin C intake.
Dietary Prevention Strategies
- Regular consumption of:
- Citrus fruits
- Berries (strawberries, amla, kiwi berries)
- Tomatoes
- Green leafy vegetables
- Nutrition education for caregivers
- Early dietary screening in high-risk children
Public health interventions emphasizing fruit accessibility have been shown to eliminate scurvy in population studies. The above details noted in the journal of Public Health Nutrition.
How Much Vitamin-C Do Children Need?
According to the Institute of Medicine and WHO guidelines:
- 1-3 years: 15 mg/day
- 4-8 years: 25 mg/day
- 9-13 years: 45 mg/day
- Adolescents (14-18 years): 65-75 mg/day
These requirements are easily met with one serving of vitamin C-rich fruit daily. According to the journal of Nutrients, MDPI.
Clinical Implication
The combination of musculoskeletal pain, bleeding manifestations, dietary restriction, and rapid response to vitamin C supplementation forms a highly specific clinical pattern for pediatric scurvy. Awareness of these findings is critical to prevent unnecessary investigations and ensure prompt, curative treatment.
Bottom Line
Scurvy in children is a preventable yet underrecognized nutritional disorder that continues to occur worldwide. Its diverse clinical presentation often leads to delayed diagnosis and unnecessary investigations. Awareness of dietary risk factors, recognition of characteristic symptoms, and prompt vitamin C supplementation result in rapid and complete recovery. Ensuring adequate intake of vitamin C–rich foods, particularly fruits such as berries and citrus, remains the cornerstone of prevention. In modern pediatric practice, scurvy should be considered whenever musculoskeletal pain and bleeding symptoms coexist with dietary restriction.
