Frostbite is a cold-related injury characterized by freezing of tissue. Most cases of frostbite are encountered in soldiers, in persons who work outdoors in the cold, in homeless people, in athletes engaging in sports with seasons extending into the cold months of the year, and in winter outdoor enthusiasts, such as Nordic skiers.
Other risk factors include chronic medical conditions (eg, diabetes, cardiovascular disease, peripheral vascular disease, Raynaud phenomena), African American race, vibration-induced white finger (VIWF), previous history of frostbite, and use of certain medications (eg, beta-blockers, sedatives). Mountain frostbite is a variation observed among mountain climbers and others exposed to extremely cold temperatures and strong winds at high altitude. It combines tissue freezing with hypoxia and general body dehydration.
