Types of Edema. Edema is the accumulation of abnormal levels of fluid in the circulatory system and the tissues between the bodyâs cells (interstitial tissue). This condition often causes tissue underneath the skin to swell, and is common when lymphatic blockage occurs.his excess fluid gets trapped in the bodyâs tissue in a greater capacity than the lymphatic system can eliminate. Generally, edema is physically unnoticeable until the interstitial fluid volume is approximately 30% above normal (normal fluid volume is 10%).
1 Edema is a swelling, usually of the legs, due to the accumulation of excessive fluid in the tissues. 2  The edema that occurs in diseases of the heart, liver, and kidneys is mainly caused by salt retention, which holds the excess fluid in the body.
