Limb shaking, vomiting and vitamin D deficiency.

Vitamin D deficiency has been identified as a medical concern for centuries. Often regarded in the context of young children and the elderly, vitamin D deficiency has become a common diagnosis in the adolescent population. Associations with other chronic conditions have not been fully explored, but medical personnel must be acutely aware in order to provide the best care. Our case presents an adolescent with a known eating disorder diagnosis and symptoms that ultimately led to an added diagnosis of Vitamin D deficiency.
