Which of the following is not a common manifestation of nephrotic syndrome?
**Core Concept**
Nephrotic syndrome is characterized by significant proteinuria, hypoalbuminemia, hyperlipidemia, and edema. It results from damage to the glomerular filtration barrier, leading to excessive loss of albumin and other plasma proteins into the urine.
**Why the Correct Answer is Right**
The manifestations of nephrotic syndrome include:
* Edema: Due to decreased oncotic pressure caused by low albumin levels.
* Hyperlipidemia: Secondary to increased hepatic synthesis of lipids in response to hypoalbuminemia.
* Proteinuria: Excessive loss of albumin and other proteins through the urine.
* Hypoalbuminemia: Decreased albumin levels in the blood.
**Why Each Wrong Option is Incorrect**
**Option A:** Edema is a common manifestation of nephrotic syndrome.
**Option B:** Hyperlipidemia is a common manifestation of nephrotic syndrome.
**Option C:** Proteinuria is a hallmark of nephrotic syndrome.
**Option D:** Weight gain is not a direct manifestation of nephrotic syndrome. Nephrotic syndrome is characterized by edema, which can lead to weight gain, but weight gain is not a specific or common manifestation of the condition.
**Clinical Pearl / High-Yield Fact**
In nephrotic syndrome, the loss of albumin and other proteins can lead to a decrease in the blood's oncotic pressure, resulting in edema. This can be a critical distinguishing feature from other types of kidney disease.
**Correct Answer:** D. Weight gain.
