Ischemia, or an Ischemic foot, refers to a lack of adequate arterial blood flow from the heart to the foot. There are a wide variety of possible causes, including arterial blockage (Peripheral Arterial Disease) from cholesterol deposits, arterial blood clots, arterial spasms, or arterial injury. With ischemic foot, the person suffers from an inadequate blood supply reaching the foot to provide the oxygen and nutrient needs required for the cells to continue to function.
Symptoms typically include cold feet, discoloration in the toes, muscle cramping, and, over time, ulcers and pain.
Treatment includes walking exercises to increase blood flow, wearing protective shoes, and medications.
Note: Please consult with your physician before taking any medication.
