Final answer:
The presentations of edema from hypoalbuminemia and primary glomerular damage (glomerulonephritis) differ in their causes, manifestations, and underlying conditions.
Step-by-step explanation:
The presentations of edema from hypoalbuminemia and primary glomerular damage (glomerulonephritis) differ in several ways:
- Causes: Hypoalbuminemia occurs when there is a decrease in the levels of albumin, a plasma protein, in the blood. This can be due to liver disease, malnutrition, or kidney disorders such as nephrosis. Glomerulonephritis, on the other hand, is caused by inflammation and damage to the glomeruli of the nephrons.
- Manifestations: In hypoalbuminemia, edema occurs as a result of a decrease in osmotic pressure in the capillaries due to low albumin levels. This causes water to move from the blood into the surrounding tissues, leading to swelling. In glomerulonephritis, edema is primarily caused by the leakage of protein, including albumin, into the urine. This leads to a decrease in albumin levels in the blood and subsequent fluid retention and edema.
- Underlying conditions: Hypoalbuminemia can be associated with a variety of underlying conditions such as liver disease and malnutrition. Glomerulonephritis, on the other hand, is typically associated with conditions such as streptococcal infections or bacterial endocarditis.
