When renal function is known to harm the development of the body's internal environment can not maintain balance, the body will lead to savings of toxic metabolites, water and electrolyte and acid-base balance disorders, and a series of clinical syndromes. In fact, this means that the arrival of chronic renal failure, chronic renal failure after the arrival, in addition to timely treatment, but also some attention in the daily diet, chronic renal failure is not an independent disease, but due to various causes deterioration of kidney damage progress of end-stage performance, mainly due slowly progressive loss of renal function, and ultimately emerge as metabolites retention, water, electricity and systemic disorders and acid-base imbalance as the main manifestation of the symptoms of the clinical syndrome.
1 to reduce protein intake. To meet the basic needs of the patient's body the protein under the premise of minimizing the intake of protein, in order to maximize ease burden on the kidney. It is estimated that the daily intake of patients with chronic renal failure suitable amount of protein per kilogram of body weight of 0.5 to 0.6 g. Eating too much protein-rich foods will increase the burden on the kidneys, so that elevated blood urea nitrogen; while protein intake can cause malnutrition, it may prompt increase in serum creatinine. Not dialysis patients, because the kidneys are unable to protein metabolism resulting from the discharge of waste, making the situation more severe renal failure, therefore, will be recommended to reduce the intake of protein; But if dialysis, are subject to note that in the wash kidney will cause the loss of body protein, it must meet nutritionist's advice, in order to maintain the body needs.
2 water intake: If excessive intake of water, the kidneys can not be excluded, it will cause edema or heart and lung failure, so the moisture control is a very important issue, the doctor depending on the amount of urine cases, or dialysis exclusion of water to determine the amount of water intake, generally in accordance with the previous day's urine output plus 500-750c.
3 Shensi potassium foods. Potassium is an important ions in the human body, involved in the metabolism and maintenance of cardiac function. Chronic renal failure patients are prone to elevated serum potassium, the heart function is affected, severe cases can lead to cardiac arrest. Main body of potassium from food intake, urinary excretion. Chronic renal failure, renal excretion dysfunction, not the body of excess potassium from the urine, it will cause elevated serum potassium.
4 Restrict intake of potassium: the accumulation of potassium can cause muscle weakness, severe cases can cause arrhythmia and cause heart failure generation.
5 Keep a low salt diet. Chronic renal failure patients often suffer from high blood pressure, low-salt diet can help prevent high blood pressure. For patients with edema, low-salt diet is particularly important, severe edema on salt intake even more strictly limited. As for drinking water, without significant edema, you do not have restrictions. Undue restrictions on drinking water, for the protection of residual renal function has no benefits.
6. Limit intake of phosphorus: phosphorus because the body will cause excessive loss of calcium, so doctors will use medications to help control blood phosphorus levels, prevent osteoporosis generation.
7 eat vegetable protein. Eat all the beans, soy and other plant foods high in protein, such as mushrooms, edible fungus, peanuts, melon seeds. Because plant proteins are crude protein, the body of lower utilization of plant protein, plant protein after eating the body of metabolic waste produced more, will increase the burden on the kidneys, so that creatinine, urea nitrogen, disease progression.
8 limit sodium intake: because salt contains a high sodium content in renal failure patients if too much sodium can cause body water retention, which causes heart and lung failure and renal failure aggravated the situation. But do not use low-sodium, low sodium due to high content of potassium ions.
9 not eat spicy food. Try not to eat chili, pepper, curry, pepper, fennel and chocolate, melon seeds, peanuts and so easy to "get angry" of the goods, should not eat fish, mussels, shrimp, crab and other seafood and allspice, aniseed, cedar, coriander and so on. Because such food is likely to cause high blood pressure, can cause allergies.
Maximum daily salt diet controlled within 2 - 3 grams or less, to prevent increased kidney burden and the degree of edema. Low-salt diet does not mean it does not eat salt, how to reasonably limited salt intake is to be elaborated in this article. Some patients in the forbidden salt or low-salt diet, due to bland dishes cause loss of appetite, affect the absorption of nutrients. At this point should adopt other methods to improve the appetite!
