Edema has many possible causes: 1  Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. 2  Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
This accumulation of fluid in the lung is called pulmonary edema. At the same time, accumulation of fluid in the legs causes pitting edema. This edema occurs because the build-up of blood in the veins of the legs causes leakage of fluid from the legs' capillaries (tiny blood vessels) into the interstitial spaces. An understanding of how the heart and lungs interact will help you better comprehend how fluid retention works in heart failure.
