1. Water control: (1) Patients with urine volume greater than 1000ml and no edema on the body do not need water restriction. (2) With edema, water restriction is needed regardless of the amount of urine. (3) Water restriction is required for urine volume less than 1000ml. (4) In the case of water restriction, the amount of water to drink is determined by the previous day’s urine volume, and generally the total amount of water intake is equal to the previous day’s total urine volume plus 500 ml. If there is high fever, vomiting or diarrhea, the amount of water intake should be increased appropriately. Daily water intake does not only mean plain water, but also includes the hidden water content in daily food intake. For example, two taels of rice contains about 60 to 70 ml of water, while the water content of fresh vegetables reaches 65% to 90%. This should also be taken into account when calculating total intake. Those with severe edema should follow medical advice to prohibit or limit water, while those with moderate edema must control water intake, and those with mild edema can drink when they are thirsty, but not too much. 2. Salt control: (1) Under normal circumstances, the total amount of salt intake is 6 – 9 grams a day. (2) Nephrotic syndrome patients with edema should pay attention to salt restriction, salt intake less than 3 grams, to the extent that the patient can tolerate, does not affect their appetite, if excessive salt intake can be excreted sodium with the help of diuretics. Do not eat brined and pickled foods; low soy sauce, 1 gram of salt is equal to 5 ml of soy sauce; try more low-salt seasonings: such as pepper, vinegar, sugar, star anise, pepper, garlic, etc. 3, protein intake: (1) patients with nephrotic syndrome with normal kidney function, the protein intake is 1 gram per kilogram of body weight per day, plus the amount lost in the urine can be. (2) nephrotic syndrome patients with azotemia (laboratory blood urea nitrogen, creatinine higher than normal), to appropriately limit the intake of protein, about 40 grams of protein per day is appropriate. High-quality protein should be selected, preferred eggs and dairy foods, an egg contains about 7 grams of protein, a bowl of milk (200 ml) contains about 8 grams of protein, a couple of lean meat contains about 9 grams of protein, chicken contains slightly more protein than lean meat, and fish slightly less. (3) Nephrotic syndrome patients with azotemia, eating less protein, they must eat more carbohydrates (such as sucrose, glucose) to supplement, in addition, should eat more vitamin-rich fresh vegetables and fruits to supplement the daily essential calories. 4, vitamins: appropriate supplementation of calcium and osteotriol to prevent osteoporosis and side effects of hormones. 5, Phosphorus: Properly limit phosphorus intake for high blood lipids: Foods high in phosphorus: dairy products (yogurt, soybeans and other legumes), animal offal (carp, squid, shrimp, mushrooms, etc.), beverages (tea, coffee, cola, beer).
