”Something or nothing to drink water, a cup of tea does not leave the mouth.” The daily water intake of the elderly should be more than 2500 ml, especially in the hot summer, pay more attention to timely hydration, to drink light tea. Drinking a lot of water can not only increase the volume of urine, to prevent urine concentration, but also promote the peristalsis of the renal pelvis and ureter, facilitating the discharge of sediment-like stones with urine, to prevent the generation of kidney stones, but also to strengthen the urinary function of the kidney, to reduce the accumulation of toxins. In addition, patients with urinary tract infections such as acute pyelonephritis, urethritis, cystitis, etc., in addition to timely consultation and medication, drinking more water and urinating more is very beneficial to the recovery of the disease. Normal people urine volume is generally 1500-2000ml a day, acute nephritis, acute renal failure, as well as nephrotic syndrome, chronic renal failure with oliguric swelling patients, to control the amount of water intake. Because drink in not out, water retention in the body to aggravate edema, but also easy to aggravate hypertension, the amount of water into the urine plus 500 ml is appropriate. The amount of water intake can be relaxed after the increase of urine volume. The amount of water intake for patients with normal urine volume is not limited. In addition, the water intake for dialysis patients depends on the specific situation. At the beginning of dialysis, due to the existence of some residual kidney function, there is a certain amount of urine, with the prolongation of dialysis time, the residual kidney function gradually lost, urine volume is less and less, it is necessary to strictly control the intake of water. In the past, there was a saying that abdominal dialysis patients could eat and drink freely, but nowadays, the view is that abdominal dialysis patients also have excessive volume load, and patients may show swelling and poor blood pressure control, and so on, and they should also follow the principle of “measure out to enter”. Can kidney patients drink soup? As long as the kidney function is normal, there is no strict restriction on what kind of soup can be made. Fish, chicken, lean meat and eggs can be used as soup, and a little bit of herbs can be added as a medicinal dish. For example, the party ginseng, Astragalus membranaceus chicken, lotus seeds, Tzusi boiled lean meat can strengthen the spleen, Cordyceps stewed duck can nourish Yin and kidney, Tu Fu Ling turtle can nourish Yin and water, etc.. For kidney insufficiency, gout patients should pay attention to avoid drinking meat soup, because the soup contains purine, phosphorus, is not conducive to kidney function, may induce gout. Can I drink strong tea for kidney disease? Drinking tea can help the digestion of food and has certain benefits. However, strong tea will affect the absorption of iron in food, especially after meals, because the tannic acid in tea and iron in food combined into insoluble precipitates, can not be absorbed by the digestive tract, due to iron deficiency affects hematopoiesis, over time, iron deficiency anemia will occur, so one hour before and after meals should not drink strong tea.
