A-Z Circulatory System Claudication Arteries are responsible for the delivery of oxygen and nutrients to all the cells in the body. When the arteries become narrowed as a result of atherosclerosis , the build-up of cholesterol or fatty deposits along the wall of the blood vessel, blood flow is decreased. The decrease in blood flow prevents oxygen and nutrients from reaching the tissues. Pain, or claudication, occurs when the muscles do not receive the oxygen and nutrients they need.
Claudication is a term used to describe the pain that occurs in the arms and legs during exercise.
Risk factors for atherosclerosis include your age, if you are over 45, smoking , elevated cholesterol , high blood pressure , coronary artery disease , diabetes , obesity or a family history of the disease.
