  The dietary guidance for nephrotic syndrome

  Patients with nephrotic syndrome often associated with gastrointestinal mucosal edema and ascites, which affects the digestion and absorption, and should take light and semi liquid diet or eat these food easy to digest. Due the loss of urinary protein, the body is in the protein malnutrition status. Before the end of 80s, a high protein diet (1.5 to 1.2 g /kg.d) was advocated to attempt to alleviate the low protein blood disease and a series of complications. But animal experiments and human kidney disease observation were confirmed: Taking high protein diet can makes the liver synthesis of albumin increased, but urinary protein excretion also increased, which is helpless to reduce hypoproteinemia and can cause the glomerular capillary perfusion in high pressure and high filtration, and easily accelerate glomerular sclerosing inflammation. Restriction of protein intake can slow down the development of chronic renal damage. Therefore, in the current the patients are advised to take high quality protein diet, and make the daily protein intake in 0.7- 1 grams per kilogram of body weight.

  The patients almost have hyperlipidemia, they should limit intake of animal fat, take the diet rich in polyunsaturated fatty acids (such as fish oil) and eat more vegetable oils (soybean oil, rapeseed oil, sesame oil). The patients with high degree of edema should limit the salt intake (the daily intake of less than 3 grams of salt) and add appropriated trace elements.

  1. sodium intake

  

 

  patients with edema should take a low salt diet, so as not to aggravate the edema. In general, the daily sodium intake is not more than 2G , which is appropriate. The patients should stop taking preserved diets, eat less monosodium glutamate and food base. When the edema subsided and the plasma protein close to normal, the patients can take normal diet.

  2. Protein intake

  

 

  When the patients are followed with nephrotic syndrome, a lot of plasma protein is discharged from the urine, causing body protein decreased and in protein malnutrition status ,at the same time, hypoproteinemia makes the plasma colloid osmotic pressure drop, which results in edema hard to decrease and body resistance decreased. Therefore, before the renal failure and in the early stage of the disease, the patients should be given a high quality protein diet (1 ~ 1.5g/kg*d), such as fish and meat, which can help to alleviate the low protein and some complications.

  3. Fat intake

  

 

  Patients with nephrotic syndrome often have hyperlipidemia, which can lead to atherosclerosis , glomerular injury and so on.

  4. Trace element supplement

  

 

  Due to the increased permeability of glomerular basement membrane in patients with nephrotic syndrome, urine not only lost a large number of proteins, but also some trace elements and hormones, which causes the human body lack of calcium, magnesium, zinc, iron and other elements. So the patients should be given the appropriate supplement and the food like vegetables, fruits, grains, and other seafood is a great choice.
