1. how to limit moisture
Food should be easy to digest and contain enough vitamins, especially vitamin B, C, D. To avoid rough food on the digestive tract mechanical damage and gastrointestinal bleeding. Patients with a good appetite for calories, the calories should not be less than 35 kg per kilogram of body weight, but to uremia can only depend on the patient's appetite. If patients with normal urine volume, edema is not obvious, generally do not limit the amount of drinking water. Because of uremia patients urine volume decreased, from mouth into the liquid will remain in the body, and causing the body edema, elevated blood pressure, and pulmonary edema, so renal failure patients must strictly limit the daily fluid intake, usually oral intake of liquid volume is approximately equal to the total row urine volume 500 ml. If sweating, can be appropriately increased. But don't forget to measure your weight every day as a reference to your drinking water.
2.Supplement enough heat
In azotemia and uremia patients should be mainly in low protein diet, and protein to the animal protein contains essential amino acids, such as milk, eggs, fish, lean meat, etc.. Daily protein intake of 20 g. This not only ensures the body's essential amino acid supply, but also allows the body in the absence of low protein supply, the use of non protein nitrogen synthesis of non essential amino acids, thereby reducing the quality of nitrogen. Uremic diet due to the limitation of protein intake, intake of Steamed Rice class is restricted, so easily lead to insufficient heat, then the body of the original protein will be consumed, but urea increased resistance to deterioration, so after the event must eat high calorie and low protein food.
3. limit protein
Under tight restrictions in protein intake, the patient should try to choose a good source of protein, can be fully utilized to repair or maintain muscle, legumes (beans exception), drupe, gluten products, grain protein, flour products, sweet potato, taro, potato, vegetables, fruits contain poor quality, will create more waste, increase the burden on the kidneys.
4. limiting potassium ion
When kidney function is not good, the human body may not be able to effectively remove excess potassium, and potassium is too high will cause serious heart conduction and contraction abnormalities, even death. Therefore, patients with uremia should eat less potassium content of high sparse vegetables and fruits, and avoid raw vegetable salad... The other content such as coffee, tea, chicken, cow essence, ginseng extract, concentrated broth, soy sauce, salt and potassium is also high, should try to eat less.
5. limiting sodium ion
Excessive sodium ions in body easily lead to blood pressure increased, edema, ascites, pulmonary water, resulting in heart failure, etc.. Salt in food, soy sauce, monosodium glutamate, tomato sauce, Satay Sauce, vinegar, etc. contain a lot of sodium, so usually uremic patients should eat less salt. Dining out, you can use boiled water diluted salt in food.
6. limiting phosphate ion
The main function of phosphorus is strengthen skeleton, patients with renal failure due to kidney cannot work normally, so the excess phosphorus will accumulate in the blood, causing hyperphosphatemia and cause skin itching and bone lesions. High phosphorus foods are milk, soda, cola, yeast (Jian Su sugar), visceral, dry beans, whole grains (brown rice, whole wheat bread), eggs, dried fish should also be careful to avoid eating.
