The lymph system helps your body fight illness. Lymph fluid travels throughout the body in lymph nodes and vessels. The fluid builds up if these nodes or vessels are blocked, damaged, or missing. Fluid build-up in the arms or legs is called lymphedema. There are two types of lymphedema:

  • Primary lymphedema is uncommon and occurs because people are either born without lymph nodes and vessels or they do not work properly.
  • Secondary lymphedema occurs when there is injury to the lymph nodes or vessels or blockage by infection or tumors.

Lymphedema can be caused by a variety of factors:

  • Primary lymphedema
    • Being born without lymph vessels and nodes or with poorly functioning ones.
    • Milroy’s disease
    • Meige disease
    • Late-onset lymphedema
