1, sodium and salt intake: edema should be into a low-salt diet, so as not to aggravate edema, generally no more than 2g of salt per day is appropriate, banned pickled foods, less MSG and alkali, edema subsided, plasma protein close to normal, you can resume the ordinary diet. 2, protein intake: nephrotic syndrome, a large amount of plasma protein excretion from the urine, the human body protein decreased and in a state of protein malnutrition, hypoproteinemia so that the plasma colloid osmotic pressure decreased, resulting in edema stubbornly difficult to eliminate, the body resistance also decreased, so in the absence of renal failure, its early, extreme phase should be given a higher quality protein diet (1 ~ 1.5g/kg * d), such as fish and meat, etc. This helps to alleviate the hypoproteinemia and some of the ensuing comorbidities. However, a high-protein diet can increase renal blood flow and glomerular filtration rate, which puts glomerular capillaries under high pressure, and the intake of large amounts of protein also increases urinary protein, which can accelerate glomerulosclerosis. Therefore, for chronic, non-polar nephrotic syndrome patients should consume a smaller amount of high-quality protein, as for the emergence of chronic renal impairment, it should be a low-protein diet (0.65g/kg * d). 3, fat intake: nephrotic syndrome patients often have hyperlipidemia, which can cause arteriosclerosis and glomerular damage, sclerosis, etc., so should limit the intake of animal offal, fatty meat, certain seafood and other foods rich in cholesterol and fat. 4, trace element supplementation: because of the increased permeability of the glomerular basement membrane in patients with nephrotic syndrome, in addition to the loss of a large amount of protein in the urine, but also the loss of protein combined with certain trace elements and hormones, resulting in the lack of calcium, magnesium, zinc, iron and other elements, should be given appropriate supplementation. Generally, you can eat vitamin and trace element-rich vegetables, fruits, grains, seafood, etc. to supplement. Diet not suitable for nephrotic syndrome: In the traditional treatment method, for patients with nephrotic syndrome hypoproteinemia, doctors mainly take the input of albumin, or recommend patients to consume a high protein diet to supplement the protein loss of the body caused by large amounts of protein urine. However, with the progress of society and step by step advancement of medical technology, this view of supplementing high protein diet is questioned. What is the reason for this? It was proved through clinical experiments that patients with nephrotic syndrome received a low-protein diet, that is, 0.8 grams of protein diet per kilogram (by human body weight) per day, and after 14 days of such a low-protein diet, laboratory tests showed that the urinary protein excretion of patients with nephrotic syndrome was significantly reduced, while serum albumin was moderately elevated. It is clear from the experiment that although the low-protein diet caused a decrease in albumin synthesis, the decrease in urinary protein excretion and the decrease in albumin breakdown, both of which were sufficient to offset the decrease in albumin synthesis. Then, in contrast, if a patient with nephrotic syndrome consumes a high-protein diet with 1.6 grams of protein per kilogram (according to human body weight) per day, the intake of high-protein diet increases protein synthesis, but the urine routine examination shows that urinary protein excretion is increasing, so that patients with nephrotic syndrome have serious kidney damage due to increased protein elimination.
