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%).
Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
