In brief: Swelling
Lymphedema is simply fluid accumulating in some part of the body quicker than the body can drain it off.
It can be due to impaired drainage or too much fluid accumulation and should be checked out with your doc.

Dr. Nguyen is correct, adding that lymphedema is specifically related to inadequate lymphatic drainage related to some obstructive lesions of the lymph nodes or ducts.

In brief: Excess fluid
There are 2 circulation systems in the body, the vascular, arteries and veins, and the lymphatic.
Fluid leaks out of the veins slowly all day long, and it should be picked up by the lymph circulation, and returned to the vascular system. The immune system also uses the lymphatic circulation to move infection fighting cells. Damage causes the fluid to back up, and causes swelling.

In brief: Specific swelling
Lymphedema is swelling due to an abnormal collection of lymph fluid in the interstitial tissue.
Lymph fluid is similar to blood plasma or serum but not exactly the same. Interstitial tissue is body tissue outside of blood vessels. As drs. Miller, nguyen and point said, lymphedema occurs when the body isn't able to drain all the lymph fluid it makes bad into the blood stream.
