Nephrotic syndrome is a kidney disorder that causes the body to transfer a lot of protein into your urine.
This disease causes swelling, especially in the legs and ankles, and increases the risk of other health problems.
The nephrotic syndrome includes a group of diseases that present with inflammation of the capillary rings of the glomerulus. These acute glomerulonephrites have a sudden onset and a short period that may progress to complete recovery, the development of nephrotic syndrome, or (end-stage renal disease).
One of the primary manifestations of these diseases is hematuria (the presence of blood in the urine) which is the result of capillary inflammation and damages the glomerular barrier against blood cells.

Symptoms of nephrotic syndrome

Severe swelling (swelling) especially around the eyes, ankles, and feet
Foamy urine, the result of excess protein in the urine
Weight gain due to fluid retention
Fatigue
 Loss of appetite

Risk factors and risk factors for nephrotic syndrome

Factors that can increase the risk of nephrotic syndrome include:
Medical conditions that can damage your kidneys.
Some diseases and conditions such as diabetes, lupus, amyloidosis, reflux nephropathy, and other kidney diseases increase the risk of developing the nephrotic syndrome.
Specific medications: Medications that may cause nephrotic syndrome include nonsteroidal anti-inflammatory drugs and medications used to fight infections.
Specific infections: Infections that increase the risk of nephrotic syndrome include HIV, hepatitis B, hepatitis C, and malaria.

Nutrition and medical treatment regimen in nephrotic syndrome

When you have nephrotic syndrome, a nutritionist may recommend changes in the amount of protein, salt, and fat you eat.

• Protein

The amount of protein you should consume depends on the health of your kidneys. For some people with nephrotic syndrome, it is best to follow a low to moderate protein diet. You should talk to a nutritionist about your protein intake.

• Salt

Limiting the amount of salt (sodium) you consume can help prevent swelling and keep blood pressure at a healthy level.

• fat

Following a low-fat, saturated cholesterol diet can help prevent high cholesterol associated with nephrotic syndrome.
