Lymphedema is the swelling of a limb or other body tissue that occurs when vessels that form the lymphatic system are blocked or there is an increase in lymph fluid. The lymph system vessels carry excess protein and fluid to the blood stream. Tiny round organs called nodes line the lymphatic system and trap toxins and foreign bodies, such as bacteria. If you have lymphedema, you can lose weight through exercise and healthy eating. Exercise may improve circulation in your lymph system and reduce the swelling of your lymphedematous arm or leg, even though lymphedema itself cannot be cured. Because lyphedema has multiple causes, there isn't a single weight loss program that will work for all lymphedema patients.

Lasinski, MA, PT, CLT-LANA, on website Lymphedema Treatment warns patients to always wear their compression garments or compression bandages on their affected limb whenever they exercise. Swimming, cycling and quick walking are less risky for lymphedema patients than tennis, bowling and jogging, but patients should feel free to engage in activities such as jogging if it does not worsen their lymphedema. If the lymphedematous limb is swollen before exercising, patients should elevate it and rest instead of exercising that day.
