Lymphedema:
A newly discovered cellular mechanism shows promise for treating painful lymphedema.
- Lymphedema is swelling in various areas of body that happens when something affects the lymphatic system.
- The lymphatic system collects excess fluid, proteins, and toxins from the cells and tissues and returns them to the bloodstream.
- When the lymphatic system doesn’t work well, the body accumulates fluid and may begin to swell.
- The swelling typically affects the arms and legs, but it can affect other areas of the body, too.
- Lymphedema can happen after certain surgeries or because of certain medical conditions or genetic conditions.
- It can be caused by cancer treatments that remove or damage the lymph nodes.
- One may develop lymphedema spontaneously, meaning it happens for no known reason.
- Lymphedema symptoms may be mild, causing minor swelling and discomfort.
- Severe cases of lymphedema can affect the ability to move the affected limb, increase the risks of skin infections and sepsis, and can lead to skin changes and breakdown.
- Once lymphedema develops, it is a chronic condition that cannot be cured but can be treated to relieve swelling and improve the ability to function day to day.
