Which of the following is NOT a feature of nephrotic syndrome?

Nephrotic syndrome is characterized by a group of clinical features that arise from significant kidney damage, particularly affecting the glomeruli. Some of the hallmark features of nephrotic syndrome include proteinuria, hypoalbuminemia, edema, and hyperlipidemia.

Hyperlipidemia is a common finding in nephrotic syndrome due to the liver's compensatory response to the low levels of albumin in the blood. The liver increases the production of lipoproteins, which leads to elevated cholesterol and triglycerides.

Infection is also a notable concern for patients with nephrotic syndrome. This arises because the loss of immunoglobulins in the urine due to increased permeability of the glomerular membrane compromises the immune response, making individuals more susceptible to infections.

Orbital edema can occur due to generalized edema associated with nephrotic syndrome. The redistribution of fluid in the body leads to swelling, especially in areas such as the eyes, which may appear more pronounced.

Hypernatremia, however, is not a typical feature of nephrotic syndrome. In fact, nephrotic syndrome often leads to hyponatremia or normal sodium levels because of the retention of water relative to sodium due to volume overload and edema. Therefore
