Let’s discuss, how can we differentiate the edema caused by Renal Failure from edema from other pathologies.

2

Renal cause :- proteinuria ->>> albumin loss ->> reduced osmotic pressure inside blood vessels ->>> led to shift of fluids from BV to interstitial space
Liver cause :- albumin synthesis hamper dur to liver pathology causing same decrease in osmotic potential

patient with acute and chronic kidney disease , pulmonary edema caused. With that chances of cardiovascular disease increases

  1. Renal failure edema is generalized (anasarca), including face and abdomen.

  2. Heart failure edema is pitting, starts in lower limbs, with raised JVP and pulmonary signs.

  3. Liver disease edema includes ascites, jaundice, and spider angiomas.

  4. Hypoproteinemia causes severe pitting edema, especially periorbital.

  5. Venous/lymphatic edema is localized, usually non-pitting.
