What Is Lymphedema?
Lymphedema is a medical condition characterized by the improper function of your lymphatic system. The lymphatic system is responsible for maintaining fluid levels in our body tissues by removing all fluids that leak out of our blood vessels. The lymphatics also function to transport fat, protein, and other nutrients, as well as prevent infections. This is all accomplished as a result of lymph fluid moving throughout your lymphatic system, through a series of lymph vessels, in addition to being filtered through lymph nodes, and eventually draining through one of the main lymphatic ducts, where it reenters the bloodstream again. Finally, the lymph fluid is drained through one of the main ducts, where it enters the bloodstream again.
In patients with lymphedema, lymph fluid builds up due to a problem with lymphatic drainage. This can be caused by a damaged lymph vessel, a blocked or removed lymph node, or any other drainage-related problem with your lymphatic system. As this lymph fluid continues to build up in the tissues, it can potentially cause visible swelling, pain, itching, and other symptoms, including skin changes and an increased risk of infections. Common causes of lymphedema include cancer, particularly breast cancer, cancer-related surgery, radiation, chronic venous disease, direct trauma, and obesity.
Compression garments for lymphedema can help promote the flow of lymph fluid, which helps reduce swelling in the affected part of the body. There are several steps to successfully managing lymphedema, including getting plenty of exercise, staying hydrated, and using compression and other treatments to reduce swelling.
