Many people complain of swelling of the legs or ankles, particularly those who stand for long periods. In many cases this can be alleviated by wearing support stockings and ensuring you have flat well-fitting shoes.
There are two other causes of swollen legs - varicose veins which reduce the efficiency of the circulation in your legs and a condition called lymphoedema. In addition to arteries which supply the leg with blood and veins which take the blood from the leg, the lymphatic system clears material which escapes from the circulation. If the lymphatic system becomes blocked or if you have a poorly developed system, you can develop swelling known as lymphoedema. In most cases, lymphoedema is treated by wearing elastic compression stockings, or through the use of an intermittent pneumatic compression pump. However in severe and advanced cases it can be treated surgically.
