Diet for renal failure

summary

Renal failure is usually caused by patients not paying attention to the treatment of chronic kidney disease, plus improper eating habits. Therefore, patients need to be treated with caution to achieve symptomatic treatment. So, what dietotherapy method does kidney failure have?

Diet for renal failure

Sodium intake: low salt diet should be taken when edema occurs, so as not to aggravate the edema. Generally, the amount of salt per day should not exceed 2G. Pickled food should be prohibited, and monosodium glutamate and alkali should be used less. When edema subsides and plasma protein is close to normal, normal diet can be restored. 　　

Protein intake: in renal failure syndrome, a large amount of plasma protein is excreted from the urine, and the body's protein is reduced, resulting in protein malnutrition. Hypoproteinemia causes plasma colloidal osmotic pressure Therefore, in the absence of renal failure, high-quality protein diet (1-1.5g / kg * d), such as fish and meat, should be given at the early and extreme stages. It is helpful to relieve hypoproteinemia and its complications. But high protein diet can increase renal blood flow and glomerular filtration rate, make glomerular capillaries in a state of high pressure. At the same time, intake of a large amount of protein can also increase proteinuria, which can accelerate glomerular sclerosis. Therefore, patients with chronic and nonpolar renal failure syndrome should take a small amount of high-quality protein (0.7-1g / kg * d), and those with chronic renal damage should take a low protein diet (0.65g / kg * d).

Supplement of trace elements: due to the increased permeability of glomerular basement membrane in patients with renal failure syndrome, in addition to the loss of a large amount of protein, some trace elements and hormones combined with protein are also lost in urine, resulting in the lack of calcium, magnesium, zinc, iron and other elements in human body, which should be given appropriate supplement. Generally, it can be supplemented with vegetables, fruits, coarse cereals and seafood rich in vitamins and trace elements. Eat more vegetables and fruits

matters needing attention

Attention should be paid to the control of salt in patients with renal failure. Water and salt can not be discharged in patients with renal failure, which is easy to cause edema and aggravate hypertension. Patients should not eat more than 5 grams of salt a day. High sodium foods, such as canned products, pickled products, pickles, pickles and fast food, should be restricted. If you have a bad appetite, you don't need to limit the salt content. You should have enough nutrition before limiting the salt content.
