Necrobiosis Ischemic

Ischemic necrobiosis is a chronic skin disease that occurs as a result of insufficient blood supply to the skin tissues. It appears as patches of redness and swelling on the fingers and toes, as well as on the face. This disease is not contagious and cannot be transmitted from person to person.

Causes of ischemic necrobiosis The first reason that causes this disease is a decrease in the amount of oxygen and nutrients that enter the peripheral vessels. The second reason is low air temperature, which affects the nervous system and blood vessels of the skin. Under such conditions, the vessels narrow, which makes it difficult for blood to reach the skin and causes necrosis. Due to insufficient supply of oxygen and nutrients, tissues become oversaturated with acid. This causes swelling, redness and pain, and in some cases, bruising.
