What foods should peritoneal dialysis patients limit?
Phosphorus Although peritoneal dialysis can remove phosphorus better than hemodialysis, hyperphosphatemia is also common in peritoneal dialysis patients. Peritoneal dialysis can remove some wastes in blood, such as urea nitrogen and creatinine, but it can also remove some substances such as phosphorus and sodium to some extent. If these substances are too high in your body, it will affect your health. Makes you feel uncomfortable. Long-term hyperphosphatemia will affect your bones and heart If the test shows that your phosphorus is too high, you should consult the medical staff during peritoneal dialysis to check whether your diet and phosphorus combination are reasonable. If the phosphorus content in the diet is too high, foods rich in phosphorus in the diet should be appropriately restricted. Such as: milk, dairy products, animal viscera such as liver, heart, intestine, kidney and brain, all kinds of novel beans and dried beans, nuts such as peanuts, melon seeds, cashews, almonds, etc., other dried vegetables such as yuba, edible fungi, tremella, various mushrooms, and cereals with complete tea leaves such as buckwheat and rye. The doctor may ask you to take more "phosphorus binders" (such as calcium for strengthening bones) to reduce the levels of phosphorus and sodium. The accumulation of sodium in the body will lead to excessive fluid in the body and elevated blood pressure. The concentration of sodium in the new peritoneal dialysis solution is very high, so the amount of sodium removed by dialysis is limited. If the salt in the diet is too high, it will cause thirst, make you drink too much liquid, increase your weight and blood pressure, and increase the burden on your heart. In severe cases, it will lead to heart failure and pulmonary edema. Therefore, we should pay attention to the usual diet, not too salty and light. And pay attention to eat less salty foods: such as soy sauce, pickled products, pickles and sauerkraut, sesame sauce, soy sauce, tomato sauce, sweet sauce, luncheon meat, ham, barbecue food, cooked food, canned products, smoked pork, caviar, pizza and so on. Cooked food in shops usually contains a lot of salt, but you may not actually feel it is salty. This is often because a lot of sugar is added to these cooked foods. The amount of salt you are allowed to eat every day is related to your urine volume and the ultrafiltration volume of peritoneal dialysate. If you don't have urine, your daily salt intake is about 2-3 grams, which is equivalent to half of our daily salt intake or 1/3. It is not easy to change the long-established habit of eating salty food. This requires your persistent efforts. The following seasonings can be used instead of salt to improve the taste of food: nose diced, pepper, mustard, ginger, novelty garlic, pepper, green pepper, lemon, vinegar, onion and so on.
