Answer

Malnutrition, hypoproteinemia, and anemia reflect the overall status of the patient and can contribute to tissue vulnerability to trauma as well as cause delayed wound healing. Poor nutritional status certainly contributes to the chronicity often seen in these lesions and inhibits the ability of the immune system to prevent infections. Anemia indicates poor oxygen-carrying capacity of the blood. Vascular disease and hypovolemia also may impair blood flow to the region of ulceration.
