Chronic Kidney Disease (CKD) stage 5 usually refers to the uremia stage, at this time, the patient’s renal function is severely impaired, and the condition is more serious. In terms of diet, it is necessary to maintain low salt, low fat, low phosphorus, high quality low protein diet; if combined with diabetes mellitus, it is also necessary to maintain diabetic diet; at the same time, it is also necessary to control potassium intake; if there is oliguria or anuria, it is also necessary to limit the water intake. 1. Low salt: when renal function is seriously impaired, nephrogenic edema may occur, and also combined with hypertension, so it is recommended that the patient’s diet should be based on low salt, and try to eat as little as possible seaweed, marine fish, shrimp and other foods. 2. Low fat: It is recommended that patients try not to eat fatty meat, animal offal, etc. Such food has high fat content, which is easy to aggravate the burden on the kidneys. 3. Low phosphorus: uremia patients are prone to phosphorus metabolism disorders, so we need to minimize the intake of high-phosphorus foods, such as animal liver, seafood and so on. 4. High-quality low-protein: should reduce the intake of plant protein such as soy, try to eat high-quality low-protein diet, such as eggs, meat, fish, oats, millet and so on. 5. Diabetic diet: If the patient is combined with diabetes mellitus, he/she also needs to actively control blood glucose, needs to maintain a diabetic diet, and minimize the consumption of sugary foods such as high-sugar cookies, cakes, and beverages. 6. Potassium intake control: Severe renal insufficiency is prone to potassium retention, so it is necessary to limit the intake of high-potassium foods such as bananas, potatoes and so on. 7. Moderate water intake: A large number of renal units are damaged in the advanced stage of the disease, and excessive water intake will lead to water retention, so moderate water intake is recommended. It is recommended that patients with chronic kidney disease stage 5 should consult a doctor in time, follow the doctor’s instructions for a reasonable diet and standardized treatment.
