Lymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized swelling caused by a compromised lymphatic system.^[2] The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream.

Lymphedema is most frequently a complication of cancer treatment or parasitic infections, but it can also be seen in a number of genetic disorders. Tissues with lymphedema are at high risk of infection because the lymphatic system has been compromised.^[3]

Though incurable and progressive, a number of treatments may improve symptoms.^[2] This commonly includes compression therapy, good skin care, exercise, and manual lymphatic drainage (MLD), which together are known as combined decongestive therapy.^[2] Diuretics are not useful.^[2]
