Edema in nephrotic syndrome is due to ?
Correct Answer: Hypoalbuminemia
Description: Ans.C.)Hypoalbuminemia Nephrotic syndrome It is a syndrome comprising signs of nephrosis, chiefly protein in the urine, low blood albumin levels, and swelling. Nephrotic syndrome is characterized by large proteinuria (>3.5 g per 1.73 m2 body surface area per day, or > 40 mg per square meter body surface area per hour in children), hypoalbuminemia (< 2,5 g/dl), hyperlipidaemia, and edema (which is generalized and also known as anasarca or dropsy) that begins in the face. Lipiduria (lipids in urine) can also occur, but is not essential for the diagnosis of nephrotic syndrome. Hyponatremia also occurs with a low fractional sodium excretion. The most common sign is excess fluid in the body due to the serum hypoalbuminemia. Lower serum oncotic pressure causes fluid to accumulate in the interstitial tissues. Sodium and water retention aggravates the edema.
