Diet in renal failure is designed to normalize, or maintain metabolic, excretory, filtering, hematopoiesis and other kidney functions. Inadmissible irritation of the organs, so the diet should be as gentle for them as possible. Diet is a prerequisite for the treatment of both chronic and acute renal failure, it is included in the general scheme of therapy of this pathological process.
The diet is based on the restriction of eating protein and salt. However, if you exclude the protein from the menu completely, then the body begins to destroy its own tissues, and if you completely abandon the salt, it threatens hyponatremia, which worsens the filtration ability of the kidneys. Therefore, doctors strongly recommend the use of specialized tables that have an optimal ratio of proteins, fats, carbohydrates and adapted for a specific disease. So, for patients with renal insufficiency it is desirable to adhere to a diet at number seven. Naturally, no one cancels the individual approach and, with the permission of the attending doctor, it is possible to introduce certain amendments. Nevertheless, it is the diet number 7 that should be taken as a basis.
In addition, there are a variety of options for this dietary table, which are adapted to this or that stage of the disease:
The 7 diet is suitable for severe chronic renal failure. It allows you to maximally spare the kidneys, facilitates the removal of nitrogen slag and protein compounds from the body. With it, you can get rid of edema and reduce arterial pressure.
Diet under number 7b is suitable for patients with moderately expressed renal failure of chronic course. It also helps to relieve the load from working nephrons and allows the removal of decay products from the body.
It is possible for chronic insufficiency to use the diet 7v. It is suitable for patients at the initial stage of chronic renal failure, as it allows to normalize the level of cholesterol, replenishes protein losses, reduces the severity of edema.
The diet numbered 7g is suitable for patients at the terminal stages of failure and with exacerbation of the disease. It is recommended to adhere to patients who are on hemodialysis.
As for the diet itself at number seven, it can be used during the remission of acute failure, when the recovery period begins from the underlying disease that caused this pathological process (nephritis, glomerulonephritis, etc.).
In addition, when selecting a diet table, one should also consider what background diseases the patient has, such as heart and vascular disease, GI disease, disruptions in the functioning of the endocrine system, etc.
Diet in chronic renal failure in the compensated and intermittent stage
Nutrition at these stages should be as gentle as possible for the kidneys. It is important to help the body to withdraw the products of the metabolism, to reduce pressure and swelling due to the withdrawal of excess fluid.

Acute renal failure is a sudden, marked violation, or a complete stop of kidney function. This pathological process is potentially reversible, although all the functions of the kidneys are affected – excretory filtration and secretory.
Chronic renal failure is the progressive decline in renal function associated with death of nephrons, or with their replacement by connective tissue, against a backdrop of chronic renal pathology. Nephrons are important structural units of the kidneys, which are involved in purifying blood from nitrogenous slags.
Derivation of metabolic products from the human body, suffering from renal failure, is recommended through the stimulation of sweating. At home, this can be achieved by visiting the sauna, using medicinal baths, sanatorium and spa treatment in regions with a dry warm climate.
