My mother has swollen feet and legs. What could this possibly mean?
– Diana, Colorado
The medical term for swollen feet and legs is peripheral edema. Edema of the lower extremities can be caused by a large number of conditions, ranging from relatively benign to life threatening.
A key question is whether or not the swelling is accompanied by pain, because this may raise the possibility of a blood clot, which is a medical condition requiring immediate attention. Another common cause of peripheral edema is venous insufficiency, which occurs when the valves in the veins of the legs — whose job is to help blood return to the heart and not pool in the legs — no longer function properly. This can be caused by phlebitis (an inflammation of the veins), previous blood clots, and prolonged standing, among other things. Potential causes of swollen feet and legs also include heart and lung problems and certain medications, including some classes of blood pressure pills and antidepressants and steroids.
A variety of tests can help determine the cause of swelling, and the appropriate therapy can then be offered. The potential for a serious condition requires investigation. So do urge your mother to seek medical care at once.
