This is a condition that arises when there is too much fluid in the tissue spaces or the cavities of the body. This can result in congestion, in inflammation the fluid accumulation we see is normal, this is part of the process, where the fluid that is rich in protein goals to the area. This is different from noninflammatory edema, where the fluid that accumulates in the is not risk in protein. This is due to the osmotic and hydrostatic pressures between the blood, vessels, and tissue not functioning properly. Intravascular hydrostatic forces and interstitial osmotic forces will move fluid in and out of the blood vessels. Opposite to this is the osmotic pressure which pushes or pulls fluid in and out of vessels. …show more content…
This can be caused by poor venous flow especially in the lower limbs due to either a deep vein thrombosis. Also, increased venous pressure caused by congestive heart failure ( right ventricle), this also causes a reduction in blood flow to the kidney. This then leads to retention of sodium and water, which then leads to the increase in blood volume.
Happens when there is a decrease in osmotic plasma pressure which is set by albumin produced by the liver. This is mainly caused by Kidney disease where albumin is excreted, meaning there is a reduction of flow through the kidney. Another disease that affects Osmotic pressure or oncotic pressure is Liver disease, Increase in portal hypertension causes an increase in hydrostatic pressure. This causes the fluid to leak out into the interstitial spaces, this causes a decrease in plasma volume which leads to reduced kidney perfusion.
Blockage of the lymph flow retention of salt and water. Edema is usually localized and because of an inflammatory response, either a neoplasm or obstruction.
