Nephritis is not terrible, nutrition come to protect2017-08-14 18:29
Kidney is one of the important organs of the body, there are metabolic waste discharge, to maintain the stability of the internal environment. Renal inflammation, glomerular endothelial cell swelling and proliferation, resulting in decreased permeability of glomerular filtration membrane and effective filtration area decreased, resulting in a sharp decline in glomerular filtration rate, but this time the renal tubular reabsorption function is relatively normal, and therefore cause water and sodium retention, increased blood volume; glomerular filtration rate decreased, the body of protein metabolites such as urea, creatinine and other obstacles, accumulation in the body lead to azotemia; inflammatory reaction can make glomerular basement membrane physical and chemical structure abnormalities, resulting in proteinuria, hematuria, long-term so that patients will cause malnutrition, hypoproteinemia and anemia.
How to take nutrition therapy?
Acute nephritis and chronic nephritis in nutrition treatment have both common ground, there is difference, mainly as the following:
1. Control the intake of liquid
When nephritis patients without edema, you may not control the liquid intake; acute nephritis if there is edema and oliguria, patients should limit the total amount of liquid, including food water and intravenous infusion, the total daily liquid intake was 500ml plus urine output of previous day; chronic nephritis patients with edema should also limit the amount of water intake, daily 1000 ~ 1500ml is appropriate.
2. Limit the intake of protein
Acute glomerulonephritis, such as early oliguria, nitrogen retention, should limit the protein intake. Should provide high bio-protein prices such as eggs, milk, lean meat, fish, etc, to reduce the burden on the kidney can also ensure nutritional balance. If control of protein is too strict, it’s adverse for the repair of the kidney unit, and protein intake is too high, will increase the burden on the kidneys. Milk or ewe's milk because it does not contain nuclear protein, it is not easy to produce uric acid, it is a priority for food.
3. Limit the intake of sodium and potassium
According to the patient's urine and edema, a reasonable limit to the diet, including low-salt diet, salt-free diet and low-sodium diet. For acute nephritis oliguria or anuria in patients, should strictly limit the supply of potassium, according to the level of potassium to adjust, to avoid eating high potassium foods such as mushrooms, beans, all kinds of fruit.
4. Appropriate energy supplement
Due to restrictions on the intake of protein, so the energy supply to carbohydrates and fat as the main source, fat is not strictly limited, but should reduce the intake of animal fats and fried foods.
How does nephritis patient choose food?
1. Appropriate foods
In the low protein diet within the limits of the protein, as much as possible the use of high-quality protein foods such as eggs, milk, lean meat and fish to increase the intake of essential amino acids. It should be noted that juvenile or anuria patients should limit the high potassium content of vegetables and fruits.
2. Avoid eating foods
Avoid having alcoholic beverages and other stimulating foods; fennel, pepper and other food metabolites containing purine, need to be discharged by the kidneys, it can increase the burden on the kidneys, acute nephritis patients should not eat. Oliguria or anuria patients should avoid high potassium foods such as mushrooms, beans, shellfish and fruit.
