Reduced blood flow.


Ischemia is reduced blood flow in any part of the body. It can cause tissue damage and loss of arms or legs if not treated right away. Reduced blood flow in the heart is called myocardial ischemia. It can lead to a heart attack.


Symptoms of ischemia can include sudden, severe stomach pain or long-lasting or severe chest pain. Stroke symptoms such as slurred speech and numbness or weakness on one side of the body also can happen. Get emergency medical help for severe pain or symptoms of stroke.


Treatment depends on what part of the body is affected and how much the flow of blood is reduced. Blood thinners and medicines that treat infections may be used. Increased exercise also may be recommended. If ischemia is severe, surgery may be done.
