Nephrotic syndrome is a clinical syndrome in which patients show a large amount of proteinuria, hypoalbuminemia, high edema, hyperlipidemia, etc. The following points should be noted in the diet: 1, patients with nephrotic syndrome with significant edema should appropriately limit the intake of water and sodium (the daily intake of sodium chloride should be less than 3 grams); 2, there are many patients who believe that their blood albumin content is low, the urine leaks a lot of protein every day, so they should be properly supplemented. In fact, this is a misconception. Patients with nephrotic syndrome should remember the phrase “the more you make up, the more you leak”, the more you make up, the more you leak, but it increases the burden on the kidneys and promotes the progress of kidney disease. Therefore, patients with nephrotic syndrome should control their protein intake appropriately, generally 0.8-1.0g/kg body weight per day. For example, if your basal weight is 60 kg, your daily protein intake should be 60*(0.8)=48 grams. Generally speaking, 1 egg contains about 6g of protein, 200ml of milk contains about 6g of protein, 50g of lean meat contains about 8g of protein (chicken contains slightly more protein than lean meat, while fish contains slightly less), when calculating protein intake, you should remember to calculate the amount of protein in the staple food category. 3, nephrotic syndrome patients often have hyperlipidemia, can cause arteriosclerosis and glomerular damage, sclerosis, etc., so should limit the intake of animal offal, fatty meat and other foods rich in cholesterol and fat; 4, nephrotic syndrome patients lose a lot of protein in the urine, but also lose some trace elements and hormones combined with protein, resulting in a lack of calcium, magnesium, zinc, iron and other elements of the body, should be given appropriate supplements. Generally, you can eat vitamin and trace element-rich vegetables, fruits, grains, seafood, etc. to supplement. 5.Appropriate restriction of calorie intake. In the process of applying hormones, patients often have a large appetite, often due to excessive food intake and weight gain, excessive obesity, so caloric intake should be appropriately restricted. In addition, adequate calcium and vitamin D should be supplemented. 6, nephrotic syndrome patients should not eat more sour, sweet, bitter, salty and cold products; eat less egg yolk, fish roe, meat skin and animal offal; avoid eating shrimp, crab, pickled products; should not drink alcohol, smoking. 7, nephrotic syndrome patients should not be greedy for cold. In summer, there are many varieties of fruits and vegetables, color and aroma to whet the appetite, but patients should strictly enforce the diet rules, do not eat more, so as not to increase the burden on the kidneys. For example, although watermelon can be diuretic and reduce swelling and heat, but more food will also increase the burden on the kidneys, in addition to the accumulation of sugar in the body of watermelon is also a potential crisis of the disease. Ice cream or chilled diet can quench thirst and eliminate heat, but if you simply crave cold is not beneficial to the disease. The reason is that the cold can damage the gastrointestinal function, so that the spleen and stomach is not healthy, and if acute enteritis occurs because of the cold, the condition will be repeated or aggravated. Therefore, patients with nephrotic syndrome should be careful with cold drinks in summer.
