A condition not so common in the 21st century but once a major concern for sailors and seafarers of medieval times, scurvy accounts for more deaths than battles, storms, or all other diseases combined. Commonly connected with malnutrition, it may be surprising that scurvy exists, even with abundant food choices and nutritional awareness. This vitamin C deficiency disorder continues to affect people worldwide, making it crucial to understand its causes, symptoms, and treatment options.

This deficiency disorder is a stark reminder of the critical role nutrition plays in human health. In this blog, we delve into scurvy, examining its causes, symptoms, diagnosis, treatment, and prevention.

What is Scurvy?

Scurvy is a condition that develops due to severe vitamin C (ascorbic acid) deficiency in the body. This essential nutrient plays a vital role in various bodily functions, particularly in the formation of collagen, a protein crucial for healthy skin, bones, and blood vessels. 

Without adequate vitamin C, the body struggles to repair tissues, leading to a cascade of debilitating symptoms. When the body lacks vitamin C for an extended period, typically 3 months or more, the symptoms of scurvy begin to appear. 

It was common among sailors in the 15th and 18th centuries due to prolonged voyages without fresh produce. Today, it is found in malnourished individuals, people with restrictive diets, and in some cases of substance abuse.

What is the Role of Vitamin C?

Vitamin C is a water-soluble vitamin that isn't stored by the body. This means we need to obtain it regularly through our diet. Fruits and vegetables are the primary sources of vitamin C. It is vital for numerous physiological functions, including: 

• Collagen production, which is essential for maintaining skin, blood vessels, and connective tissues.
• Immune system support, which enhances white blood cell function to fight infections.
• Antioxidant properties of vitamin C protect the cells from oxidative damage.
• Facilitating absorption of non-heme iron from plant-based foods.
• Promotion of wound healing.
• Production of neurotransmitters.

Symptoms and Causes of Scurvy 

Scurvy progresses gradually, with early signs often overlooked until the condition worsens. Symptoms can be divided into early-stage or primary-stage and advanced-stage manifestations:

Primary Symptoms:

• Fatigue and weakness
• Swollen, bleeding gums
• Painful joints and muscles
• Easy bruising
• Slow wound healing
• Dry, rough skin
• Red spots on the skin or petechiae
• Corkscrew-shaped body hair

Advanced Symptoms:

• Depression and anxiety
• Severe joint pain
• Tooth loss
• Internal bleeding
• Poor wound healing
• Jaundice
• Fever
• Convulsions
• Anaemia

Common Causes: 

Scurvy is directly linked to a vitamin C deficiency, due to insufficient dietary intake or other factors affecting its absorption and utilisation.

• Poor diet lacking fresh fruits and vegetables
• Alcoholism and substance abuse
• Eating disorders like anorexia nervosa
• Mental health conditions affecting diet
• Certain medical conditions affecting nutrient absorption
• Restrictive diets
• Limited access to fresh produce
• Increased dependence on processed foods
• Malabsorption disorders like Crohn’s disease, Celiac disease, etc
• Increased nutritional demands in the case of pregnant and lactating women
• Chronic illnesses like renal failure, cancer, or infections

Scurvy in Children

As a rare medical condition compared to other nutritional deficiencies, scurvy is often misdiagnosed as other diseases. It can be observed in children with abnormal dietary habits, malabsorption issues, physical disabilities, or mental illness. 

Early symptoms of scurvy in children include:

• Irritability
• Joint pain
• Lack of appetite
• Anaemia
• Petechiae (tiny spots of bleeding under the skin)
• Weakness
• Poor wound healing
• Failure to gain weight

In children, scurvy can manifest in two ways:

1. Children with mobility issues: Children with certain neurological conditions that affect mobility might not experience joint pain commonly associated with scurvy. In such cases, the chances of scurvy might be suspected only when they show additional signs and symptoms, like bleeding gums or bruising. 
2. Children without mobility problems: For children without mobility issues, early symptoms of scurvy may include joint pain, weakness, and loss of mobility.

Joint pain in children is often misdiagnosed as arthritis, given that scurvy is a rare condition. However, joint pain can be a symptom of various other diseases or conditions, apart from arthritis. Given the broad range of potential causes, a thorough medical examination by a paediatric rheumatologist is essential to make an accurate diagnosis and appropriate treatment.

Diagnosis and Tests for Scurvy 

Diagnosing scurvy requires clinical evaluation, dietary history, and laboratory investigations to confirm vitamin C deficiency and rule out other conditions with similar symptoms. Timely diagnosis is critical, as untreated scurvy can lead to severe complications.

Clinical Evaluation:

The diagnostic process begins with a thorough assessment of symptoms and physical signs:

• Symptoms: Fatigue, swollen and bleeding gums, bruising, and delayed wound healing.
• Physical Examination: 
  • Presence of petechiae (small red or purple spots caused by bleeding).  
  • Swollen joints and signs of musculoskeletal pain.  
  • Evidence of gum disease or loose teeth.

Dietary History: 

A detailed review of the patient’s eating habits to identify low intake of vitamin C-rich foods such as fruits and vegetables. It involves a discussion of lifestyle factors, including substance abuse or restrictive diets.

Laboratory Tests:

Laboratory investigations play a crucial role in confirming the diagnosis of scurvy. The common tests done include:

• Serum vitamin C levels (below 11 μmol/L confirm deficiency)
• Complete blood count (to detect anaemia)
• Imaging (to identify  skeletal abnormalities in severe cases)

Differential Diagnosis:

Conditions like gingivitis, vasculitis, or coagulation disorders may mimic scurvy and must be ruled out by conducting tests for the same.

Early diagnosis and treatment are crucial to prevent complications and promote a full recovery. At Amrita Hospital, Kochi, we utilise advanced diagnostic tools and techniques to ensure precise identification of nutritional deficiencies like scurvy. Our multidisciplinary team of specialists works collaboratively to provide personalised care, addressing both the root cause and its symptoms.

Treatment and Care for Scurvy 

Scurvy is a completely treatable condition when diagnosed early and managed appropriately. The focus of the treatment is replenishing the body’s vitamin C levels and addressing any complications caused by the deficiency. 

A comprehensive care plan also includes dietary improvements, supportive treatments, and monitoring for recovery.

Vitamin C Supplementation: 

The primary treatment for scurvy is vitamin C replacement therapy.

• Oral Supplements: Adults typically require 300–1000 mg of vitamin C per day for 1–2 weeks until symptoms improve. 
• Maintenance doses of 75–90 mg daily will help prevent recurrence.
• Intravenous Vitamin C is administered in severe cases where oral supplementation is not possible due to malabsorption or gastrointestinal issues.

Dietary Modifications:

Improving the diet to include vitamin C-rich foods is essential for long-term recovery and prevention.  

• Fruits: Oranges, lemons, strawberries, kiwi, and guavas.
• Vegetables: Bell peppers, broccoli, spinach and tomatoes.

An expert dietician can help develop a balanced meal plan tailored to the patient’s needs and preferences.

Management of Symptoms:

Scurvy can lead to various complications, which require additional medical attention:  

• Gum Health: Treatment for swollen and bleeding gums may involve professional dental cleaning and mouth rinses.
• Wound Care: Special wound care is needed for ulcers or slow-healing injuries.
• Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) or other pain management strategies may be employed for joint and muscle pain.
• Anaemia Treatment: In cases where anaemia develops, iron supplementation or transfusions may be necessary.

Preventive Measures for Scurvy 

Preventing scurvy is simple and revolves around maintaining adequate levels of vitamin C through a balanced diet and healthy lifestyle practices. By ensuring proper nutrition and addressing risk factors, individuals can avoid this entirely preventable condition.

Dietary Strategies: 

• Incorporate vitamin C-rich fruits and vegetables like citruses, papayas, green leaves, bell peppers, etc. in your daily meals.
• Opt for fresh and raw produce to retain their nutritional value, as vitamin C is sensitive to heat and light. Also, avoid overcooking or reheating foods rich in vitamin C.
• Combine vitamin C-rich foods with a diet that includes proteins, healthy fats, and whole grains.
• Focus on the variety of foods to ensure all essential nutrients are consumed.

Healthy Lifestyle Practices: 

• Reduce substance abuse like excessive alcohol consumption and smoking, which can deplete vitamin C levels. 
• Seek medical advice to manage diseases that affect nutrition absorption, like Crohn’s disease or coeliac disease.

Consumption of Supplements:

• For individuals with dietary restrictions or increased nutritional needs, vitamin C supplements can be taken under medical supervision.
• Pregnant and breastfeeding women, as well as people recovering from illnesses, may benefit from additional supplementation.

Awareness and Education: 

• Periodic consultations with a healthcare provider can help detect early signs of nutritional deficiencies.
• Spreading awareness regarding the importance of vitamin C and its role in health.
• Community health programs and nutritional counselling can empower individuals to make informed dietary choices.
