Edema in the lower part of the body

Hypophyseal edema is a typical sign of right heart failure. Occurs from jugular vein filling and liver enlargement, and most cases later occur in isolated right heart failure subcutaneous edema. May be the first sign of heart failure. Before causing peripheral depression edema, a large amount of extracellular fluid must be accumulated. It is generally believed that the weight has increased by about 10% before the occurrence of edema, that is, when body fluid retention exceeds 5 kg, the water in the tissue gap of normal adults with edema appears to be about 7 kg, and in heart failure, the water can increase to 15-20 kg. Circulating blood volume and intracellular water in the extracellular space, extravascular space, and interstitial space only increased slightly. Hypnotic edema is also an early sign of cardiogenic edema.
