Dialysis Patients Should Be Cautious When Eating These 4 Types Of Food!

Although dialysis can help patients remove excess water and toxins, neither peritoneal dialysis nor hemodialysis can work like your own kidneys do all the time. Ordinary people sometimes accidentally eat the wrong thing, it may just be diarrhea, stomach pain, and other discomfort. For dialysis patients, it can be fatal.

Therefore, in terms of diet, dialysis patients must tighten the string. Today, I would like to talk to dialysis patients about the daily foods that dialysis patients should pay special attention to.

1. Pay attention to foods with high water content

Whether water control is good or not is related to the quality of life of dialysis patients and the length of life. When people with kidney disease enter maintenance dialysis, the ability of the kidneys to drain water is significantly reduced, and the excess fluid volume requires dialysis to remove. If the water intake is too much in the intermittent period of dialysis, resulting in excessive accumulation of water in the body, it may cause headache, fatigue, high blood pressure, and edema, and may lead to heart failure and death in severe cases. In addition to controlling your water intake, you should also pay attention to foods with high water content.

1 Hemodialysis

For hemodialysis patients, it is generally recommended that fluids be limited to less than 1L (1000ml) per day. Strive to control the weight gain within 3-5% of the dry weight during the dialysis period (calculation of the weight gain during the dialysis period = the weight before dialysis - the weight at the end of the last dialysis). For example, for a person with a dry weight of 60 kg, it is better to gain less than 1.8-3 kg of body weight during dialysis. Dry weight is the minimum weight a patient can tolerate without excess water.

2 peritoneal dialysis

If peritoneal dialysis patients have low urine output, edema, blood pressure > 140/90mmHg, or weight tends to increase, fluid intake needs to be controlled

Liquid/semi-liquid foods: porridge, soup, soy milk, milk, tea and other beverages, lotus root starch, etc.

2. Watch out for foods high in salt

A low-salt diet is beneficial for maintaining cardiovascular health in dialysis patients. And another consideration is that eating salty food will make you thirsty, making it easier to drink more water. The essence of salt restriction is sodium restriction. A low-salt diet requires that the total daily salt intake be controlled within 5g, that is, to control sodium within 2000mg (1g of salt ≈ 400mg of sodium).

In addition to light meals, other foods with high salt content should also be paid attention to: such as pickled vegetables, preserved fish and bacon, candied fruit, plum snacks, instant noodles, ham, salted duck eggs, preserved eggs, various snacks, pay attention to shopping Be careful with the sodium content on the package, with foods above 400mg sodium per serving.

3. Pay attention to the potassium content in food

Serum potassium is one of the indicators that dialysis patients must pay close attention to. When the glomerular filtration rate is lower than 20ml/min, the ability of the kidneys to excrete potassium will decrease significantly. During the dialysis interval, patients with kidney disease eat a lot of high-potassium foods, and potassium will accumulate in the blood, especially in hemodialysis patients, hyperkalemia is prone to occur, ranging from numbness of the lips and limbs, to death in severe cases.

Not only is high potassium dangerous, but low potassium is equally dangerous. Because the dialysate does not contain potassium in peritoneal dialysis, potassium ions are continuously lost through the dialysate, and many peritoneal dialysis patients have hypokalemia. Both are handled differently. For dialysis patients who are prone to high serum potassium, they should be alert to the large intake of high-potassium foods; while for dialysis patients who are prone to low serum potassium, in turn, appropriate intake of high-potassium foods. Potassium mainly comes from food, especially plant foods, such as fruits and vegetables, which generally contain more potassium.

4. Pay attention to foods high in phosphorus

In addition to water, sodium, and potassium in food, phosphorus also needs attention. Poor control of blood phosphorus can lead to symptoms such as skin itching and restless legs syndrome in light cases, and cardiovascular diseases in severe cases. Phosphorus in processed foods is the most important thing to pay attention to. They are easier to absorb and higher than the phosphorus in natural foods:

Processed foods high in phosphorus: ham, sausage, burgers, chocolate, etc.

High-phosphorus beverages: milk tea, beer, carbonated drinks, etc.

High-phosphorus sauces: sesame paste, curry powder, etc.

Whether it is a new dialysis patient or a patient who has been on dialysis for many years, I hope everyone can treat their bodies kindly and work hard together!
