Vitamin C (Ascorbic Acid) Deficiency and Excess
Vitamin C imbalances can occur in both deficiency and excess.
Vitamin C Deficiency results in a disease known as Scurvy. Symptoms include anemia, swollen gums, corkscrew hair, immunocompromise, and bleeding. The bleeding abnormalities can manifest as bruising, petechiae, hemarthrosis, subperiosteal hemorrhage, and perifollicular hemorrhage.
Vitamin C Excess is rare, and presents clinically with fatigue, nausea/vomiting, calcium oxalate kidney stones, and increased risk for iron toxicity (hemochromatosis).
