Learning the oral and cutaneous signs of micronutrient deficiencies.

Wound healing is a complex process that is influenced by multiple systemic factors, including nutritional status. While nutritional support is commonly recognized as an important aspect of comprehensive wound management, the focus is typically on replacement of macronutrients, specifically calories and protein. Our experience strongly suggests that micronutrients are equally important, that micronutrient deficiencies are common, and that correction of these deficiencies frequently leads to wound healing when incorporated into a comprehensive wound management program. This article provides guidelines for assessment and management of micronutrient deficiencies.
