Chronic renal failure is the final outcome of the development of various chronic kidney diseases. At this time, renal function has been damaged to varying degrees, which has caused patients to be quite confused about their diet.

The reason is that on the one hand, the patient has malnutrition, decreased physique, and low immunity, so he needs to supplement protein. On the other hand, the patient is unable to completely excrete protein and other metabolites such as urea, creatinine and other toxic substances in the urine due to impaired renal function. , Resulting in increased blood urea and creatinine concentration, so it is necessary to control the intake of protein foods.

It is precisely because of this contradiction that patients with chronic renal failure are in a very contradictory situation in terms of diet, and this situation also makes doctors very difficult to treat.

The diet of patients with chronic renal failure should pay special attention to the balance of protein, heat, vitamins and water and salt.

First, it is necessary to limit protein intake according to the condition. The principle is to try to reduce the increase in blood urea nitrogen on the one hand, and on the other hand to meet the nutritional needs of patients. In the choice of protein, high-quality protein should account for more than 50%. In the low-protein diet, the supply of heat energy must be sufficient. The daily intake of heat energy is at least 146 kJ per kilogram of body weight, and 8368-10460 kJ per day.

Second , due to abnormal metabolism and insufficient nutritional intake in patients with chronic renal failure, the level of water-soluble vitamins in the body often decreases, and abnormal calcium and phosphorus metabolism affect the synthesis of active vitamin D3, so it is very important for patients to pay attention to the supplement of various vitamins.

Third , to be noted that the intake of sodium, potassium, calcium, phosphorus and the like , an ideal treatment should increase dietary calcium content, phosphorus content decreased. If combined with edema and hypertension, sodium should be restricted; if the patient is taking diuretics or accompanied by vomiting or diarrhea, sodium should not be restricted or even supplemented.

If the patient has oliguria or hyperkalemia, attention should be paid to limit the intake of potassium ; if the daily urine output and blood potassium content are normal, there is no need to limit the potassium intake. For potassium-restricted diets, fruit juices should be avoided, and vegetables and fruits should be carefully selected. If the patient's daily urine output is greater than 1500 ml, the blood potassium content should be observed, and potassium supplementation should be required if necessary.

Fourth , in addition, it is also very important to know the balance of the patient's fluid intake and output. Generally, the intake depends on the output. In order to ensure a better therapeutic effect, patients with chronic renal failure should be guided by a doctor to ensure adequate nutrition and a reasonable dietary structure, as far as possible on the premise of nourishing the kidneys without damaging the kidneys and increasing the burden on the kidneys. The nature of cold and heat and the characteristics of your own physique, choose appropriate diet and appropriate medicated diet for conditioning.
