Hemodialysis is a kind of blood purification technology, which plays a very important role in relieving symptoms and prolonging survival time of patients with nephropathy. In addition to the care of patients by professionals in hospitals, daily care at home is equally important. Pay attention to the following points in diet. ① Pay attention to controlling the amount of drinking water. Water intake is very important for dialysis patients. In order to avoid excessive weight gain, it is suggested that the daily drinking water should be controlled within 5% of the net weight. Because uremia patients will have less urine, and the removal of water mainly depends on dialysis, so it is necessary to limit the intake of drinks and soup, and the cooking of dishes can be thickened to increase smoothness. ② Reduce blood fat. Hyperlipidemia is the main cause of cardiovascular diseases in dialysis patients, so cooking should be boiled, steamed and scalded, avoiding cooking methods with high sugar, high oil and high salt such as honey juice, sweet and sour tomato juice, frying and frying. Olive oil rich in monounsaturated fatty acids and with blood lipid lowering function can be selected. ③ Reduce the intake of potassium, phosphorus and sodium electrolytes. Excessive potassium intake will cause hyperkalemia, arrhythmia and heart failure in dialysis patients, while hyperphosphatemia will cause hyperparathyroidism and skin itching in dialysis patients. Therefore, vegetables can be scalded before cooking to reduce the intake of potassium ions. Dried fruits such as pistachios are rich in phosphorus and should be eaten less. Salt intake should be limited to prevent hypertension and heart failure. ④ Pay attention to the absorption of high-quality protein. Because the process of dialysis is to drain the blood containing toxins to the dialysis machine through arteriovenous fistula and then flow back to the body, protein will be lost in this process, so protein's intake is mainly high-quality animal protein, such as eggs, milk, fish and lean meat. In the daily diet, we should also pay attention to supplement iron, calcium, zinc, vitamin B, vitamin C and other foods, and we can also consume appropriate amount of sugar to increase calories. In addition, if dialysis patients have constipation, their blood potassium is more likely to be high. At this time, eating more high-fiber food can not only improve constipation but also improve hyperlipidemia. In a word, only by grasping the principles of high-quality protein, proper calories, low cholesterol, low phosphorus, low potassium, high iron, high fiber diet and water restriction can dialysis patients be healthier. In addition, we should do the following: ① Pay attention to psychological counseling. Psychological counseling and creating a good family atmosphere will make dialysis patients feel happy and warm. Because some dialysis patients will be accompanied by different degrees of other organ damage, blindness, neuritis, cardiac insufficiency and other complications, so that their physical and mental pain is beyond words, often leading to their bad temper and boring life. In daily life, we should observe more, ask more questions, comfort more, encourage more, communicate more, give psychological guidance to dialysis patients, let them relax and recover as soon as possible. ② Measure blood pressure regularly. The pathogenesis of hypertension in long-term hemodialysis patients is multifactorial. In home care, it is necessary to measure blood pressure regularly and repeatedly, monitor the physical condition of dialysis patients, and master the condition. ③ Pay attention to physical exercise. Pay attention to the cleanliness of patients, maintain a good attitude towards life, take an active part in physical exercise, and pay attention to changing clothes when changing seasons. 4 Ensure adequate sleep.
