Subperiosteal hemorrhage from periosteal vessel fragility
Role in iron metabolism
Enhances non-heme iron absorption in the gut
Facilitates ferritin iron mobilization
Deficiency contributes to iron deficiency anemia
Antioxidant depletion effects
Ascorbic acid is major aqueous-phase antioxidant
Deficiency increases oxidative stress
Contributes to impaired immune function and wound healing
Neurotransmitter synthesis effects
Cofactor for dopamine beta-hydroxylase (norepinephrine synthesis)
Contributes to autonomic dysfunction and mood changes
Fatigue and depression partly neurochemical in etiology
Body storage and depletion timeline
Total body ascorbic acid pool approximately 1500 mg
Symptomatic deficiency after 1 to 3 months of zero intake
Clinical scurvy after 3 to 6 months of severe deficiency
Therapeutic Considerations
Treatment response characteristics
Clinical recovery timeline
Fatigue and pain: improve within days
Skin and gum findings: resolve within 1 to 2 weeks
Radiographic bone changes: months for full healing
Route of administration considerations
Oral preferred for most presentations
IV required only when oral absorption impaired or intake impossible
Bioavailability of oral ascorbic acid approximately 70 to 90% at low doses
Recurrence prevention
Scurvy recurs if underlying dietary inadequacy not corrected
Maintenance supplementation required in high-risk patients
Addressing social determinants essential for sustained recovery
Evidence base for treatment
No large randomized controlled trials for optimal dosing regimen
Standard 100 mg TID or 500 mg daily widely used and effective
Expert consensus supports empiric treatment when clinical diagnosis strong
Safety of supplementation
Ascorbic acid well tolerated at therapeutic doses
GI upset (diarrhea) with high oral doses
Hyperoxaluria risk above 1 g/day especially with renal impairment
G6PD deficiency: IV vitamin C risk of hemolysis requires dose reduction

Diagnosis and cause
Diagnosis of scurvy (vitamin C deficiency)
Caused by not getting enough vitamin C in your diet
Can develop after 1 to 3 months of eating very few fruits and vegetables
Treatment prescribed
Vitamin C supplements as prescribed (typically 100 mg three times daily for 1 month)
Take with or without food
Do not stop early even if you feel better
Diet instructions
Foods high in vitamin C
Citrus fruits: oranges, grapefruits, lemons
Bell peppers, strawberries, broccoli, tomatoes, kiwi
Eat these daily to maintain vitamin C levels
Food preparation guidance
Avoid boiling vegetables which destroys vitamin C
Lightly steam or eat raw when possible
Activity and wound care
Limit activity if joint pain or bone pain present
No heavy lifting or running until symptoms resolve
Use crutches or assistive devices if walking is painful
Wound care
Keep any skin wounds clean and covered
Wounds may heal slowly until vitamin C is replenished
Expected recovery
Timeline
Fatigue and pain improve within a few days
Bruising and skin changes improve within 1 to 2 weeks
Full recovery may take 1 to 2 months
Recurrence warning
Scurvy can return if vitamin C intake is not maintained after treatment
Return to emergency department
Red flag symptoms requiring immediate return
Fainting or near-fainting
Chest pain or severe shortness of breath
New joint swelling with severe pain or inability to move joint
Worsening bleeding or large new bruises
Vomiting blood or blood in stool
Severe headache or confusion
Inability to eat or drink
Follow-up instructions
See your family doctor in 1 to 2 weeks
Blood test to check vitamin C level and blood count
Continue vitamin C supplements until doctor advises stopping
Social support
If you are having difficulty affording food, ask about food bank and community programs
