Lymphedema, or lymphatic obstruction, is a long-term condition where excess fluid collects in tissues causing swelling (edema). The lymphatic system is a part of the circulatory system and vital for immune function. Lymphedema is caused by a blockage of this system. Lymphedema commonly affects one of the arms or legs. In some cases, both arms or both legs may be affected. Some patients might experience swelling in the head, genitals, or chest. Lymphedema is incurable, but with the right treatment, it can be controlled.
