Angular stomatitis, or angular cheilitis, may occur in patients with iron-deficiency anemia. It is characterized by swollen, painful fissures at the corners of the mouth.

One fifth of patients with chronic iron-deficiency anemia develop cold intolerance, which is manifested by vasomotor disturbances, neurologic pain, or numbness and tingling.

Regardless of its cause, severe anemia may produce hypoxemia, which can augment the occurrence of coronary insufficiency and myocardial ischemia. Similarly, it can worsen the pulmonary status of patients with chronic pulmonary disease.
