Lymphedema

Lymphedema is a condition characterized by swelling caused by the buildup of lymph fluid in the body's soft tissues.

Lymphedema is the name of a type of swelling. It happens when lymph builds up in your body's soft tissues. Lymph is a fluid that contains white blood cells that defend against germs. It can build up when the lymph system is damaged or blocked. It usually happens in the arms or legs.

Causes of lymphedema

  • Infection
  • Cancer
  • Scar tissue from radiation therapy or surgical removal of lymph nodes
  • Inherited conditions in which lymph nodes or vessels are absent or abnormal

Treatment

Treatment can help control symptoms. It includes exercise, compression devices, skin care, and massage.

Frequently Asked Questions

Daily management typically involves a combination of strategies. This includes regular, gentle exercise to promote lymph flow, meticulous skin care to prevent infection, wearing compression garments or using compression devices as prescribed, and performing self-massage techniques (manual lymphatic drainage) if taught by a therapist. Consistency is key to controlling symptoms.
You should seek emergency medical attention if you experience sudden, significant worsening of swelling, severe pain, redness, warmth, fever, or red streaks on the skin. These could be signs of a serious infection (cellulitis) that requires immediate treatment to prevent complications.
Early signs can include a feeling of heaviness or fullness in a limb, aching, tingling, or slight swelling that may come and go. The skin might feel tighter or thicker, and clothing or jewelry may feel constricting. It's important to report any of these changes to your doctor promptly, especially if you've had lymph nodes removed or radiation therapy.
Yes, in some cases, lymphedema can be inherited. This is known as primary lymphedema and occurs when lymph nodes or vessels are absent or abnormal from birth due to genetic factors. However, most cases of lymphedema are secondary, meaning they develop as a result of damage to the lymphatic system from other causes like surgery, radiation, or infection.
