Swelling of the Extremities

Alternate Names : Peripheral Edema, Swelling of the Arms OR Legs, Swelling of the Limbs

How is the condition diagnosed?

First, a history and physical exam are done. Sometimes this is all that is needed to determine the cause of the swelling. In most cases, however, more tests are needed. The tests used depend on the suspected condition. For example, blood tests are commonly ordered. If heart failure is suspected, a heart tracing, called an ECG, may be obtained. This test looks at the electrical activity of the heart. A chest x-ray and an echocardiogram to look at the heart may also be done in this case. Blood tests and special x-ray tests may also be used to diagnose blood clots and liver or kidney problems. Other tests may be ordered in other cases.
