The lymphatic system transports fluid throughout the body, filters it in the lymph nodes, and returns the fluid back to the circulatory system. Lymphedema occurs when lymphatic fluid cannot drain properly, usually out of an arm or leg. The collection of fluid causes the symptoms of the condition, including swelling, heaviness, and skin changes.
What is Lymphedema?
The lymphatic system plays a key role in our immune system and circulatory system, but when it runs into trouble, lymphedema can result. Lymphedema occurs when the lymphatic fluid has stopped draining out of an area properly. This causes the tissues in the area to swell with fluid. The swelling often bothers people the most since it can be very visible and restrict normal motion. In some cases where Lymphedema occurs as a result of chronic venous insufficiency or other venous problems, the lymphedema should respond to endovenous laser ablation.
