The dietary contraindications for uremia are limiting protein food intake and avoiding foods that are high in salt, fat, potassium and phosphorus. At the same time need to limit the intake of water and so on. 1. Limit protein food intake: limiting protein diet can reduce the generation of nitrogen-containing metabolites and alleviate symptoms and related complications. Dialysis patients can consume a moderate amount of high-quality low-protein foods, such as eggs, milk and lean meat. 2. High salt: such as salted vegetables, all kinds of pickled food, as well as salty snacks. Eating too much high salt food may increase the burden on the patient’s kidneys, aggravate edema, cause high blood pressure, and in severe cases may even lead to acute left heart failure. 3. High fat: such as fried, animal fat food, etc. Eating too much high-fat food, aggravate gastrointestinal burden, and may aggravate hyperlipidemia. 4. High potassium: such as Chrysanthemum coronarium, black dates, pea shoots, etc., due to uremia can lead to potassium metabolism disorders, hyperkalemia is easy to cause the risk of cardiac arrest, so patients with uremia should be strictly limited potassium intake. 5. High phosphorus: such as mushrooms, nuts, animal offal, etc. High phosphorus can easily lead to renal osteodystrophy. 6. Restriction of water intake: patients with uremia have impaired fluid excretion, therefore, water intake should be restricted to avoid causing edema, even leading to acute left heart failure. Uremia patients are recommended to go to the regular hospital in time, under the guidance of the doctor standardized treatment.
