The principle of diet in patients with acute nephritis

Stop eating salt at the beginning of acute nephritis onset. Because the urinary capacity of the kidney is weakened at this time, if the salt that is eaten cannot be discharged normally, it will accumulate in the body, and at the same time, it will also produce water retention. Generally speaking, one gram of salt can leave 120 milliliters of water, which will increase the edema. The purpose of abstaining salt is only here. It should be noted that salt has no effect on nephritis, and eating salt does not aggravate the kidney disease. Therefore, when nephritis improves, renal function gradually recovers, and urine output increases, disengagement of salt can be eliminated. To know that long-term abstain from salt is not only difficult to cook, food is light and tasteless, but also affect the child's appetite, resulting in malnutrition, and even worse, hyponatremia. Can you use salt substitutes or "alkali autumn stones" during salt withdrawal? The answer is: on behalf of salt or "alkaline autumn stone" is actually potassium chloride, in the early stages of acute nephritis, renal insufficiency, often have hyperkalemia, food salt, alkali autumn stone, no doubt, on the fire, Aggravating hyperkalemia, with a slight carelessness, may lead to fatal danger. Of course, eating during the diuretic period and recovery period is harmless. In fact, this kind of salty taste is hard to eat. Most children are reluctant to eat.

Abstinence protein acute nephritis at the beginning of the onset of kidney dysfunction, and eat the protein, the metabolic waste must be excreted by the kidneys, it should not eat too much protein-containing foods, including meat, eggs and vegetable protein containing High beans, etc., will increase the accumulation of metabolic waste in the blood, namely azotemia. However, long-term withdrawal of protein is not required. As long as renal function improves, diuretic swelling appears in clinical practice, and blood urea nitrogen (BUN) returns to normal, normal diet can be used. One hundred days of folklore abstinence is unfounded. In acute nephritis, the protein does not damage the kidney, but in the process of kidney recovery, some amino acids derived from protein breakdown are also needed. Long-term low protein is not conducive to children's growth and development. Light acute nephritis can limit protein intake, if the patient has a large amount of proteinuria, then it is necessary to reduce protein intake.

Restricted water general nephritis does not have to limit drinking water, patients with edema, most will not thirsty, do not drink too much water. Patients with severe edema and less urine output will be restricted to water; patients with acute renal failure should be severely restricted to water. If there is no need, do not infuse fluids intravenously. In order to reduce the amount of water intake, even decoctions should be limited. Because in this case, like a child of 25 kilograms (about 7 to 8 years old), the water that enters the body everyday (including drinking, intravenous drip, etc.) cannot exceed 400 ml plus the amount of urine of the day. A bowl of Chinese medicine has already taken more than half of this limit, limiting the amount of fluid that needs to be supplemented. Do not think urine is not enough water, but use water to diuretic.

Fruits generally do not have to quit fruit, but do not advocate eating too much fruit, especially in patients with severe conditions. This is due to poor kidney function, limited potassium discharge capacity, and fruit potassium is very abundant, eating more blood potassium will increase, if the original high blood potassium, it is very dangerous. In patients with renal failure and high potassium levels, they must quit fruits and other high-potassium foods such as sweet potatoes, potatoes, bamboo shoots, mushrooms, cabbage, mustard, beans, peanuts, and walnuts. It is beneficial for patients to recover if they eat fruit during the recovery period.
