Limb ischemia refers to a condition where there is a lack of blood flow to a limb, usually an arm or a leg. This reduced blood supply can occur due to narrowed or blocked arteries, which can be caused by various factors like blood clots or cholesterol buildup. When a limb doesn't receive enough blood, it may not get sufficient oxygen and nutrients, leading to pain, weakness, or even damage to the tissues. It is a serious condition that requires medical attention to prevent further complications or loss of the limb.
