The weather is unpredictable, which makes it less beautiful, and it is a time of high recurrence of kidney disease, which makes parents of children and health care professionals worry about it. Therefore, parents should do a good job of preventive care for their children in autumn to prevent the recurrence of kidney disease. It is recommended that we do the following: a. Prevention of colds: from the beginning of autumn the climate becomes dry, the temperature gradually decreases, the temperature difference between morning and evening is large. Patients with kidney disease due to poor resistance a little inattention will be cold, respiratory symptoms. Especially the elderly and children are less adaptable and tolerant to climate change, and the chance of infection increases; cold stimulation in winter will cause vasoconstriction and increase blood pressure, especially cold will aggravate the condition and serious complications will occur. Therefore, we should pay attention to warmth in autumn and winter according to seasonal changes, add and subtract clothing with temperature changes, prevent cold and warmth, prevent colds and improve the adaptability of the body to climate change. Second, scientific diet: 1, protein supply: due to the special nature of kidney disease, should be under the guidance of doctors to develop scientific recipes, the protein in the diet should be moderate, too much protein intake will increase the load on the kidneys, so that renal insufficiency or deterioration, but too little may lead to malnutrition and hypoproteinemia. Usually, it should not exceed 1g per kg body weight per day, and the quality protein should reach more than 50%. 2. As some children are restricted to protein, their caloric energy supply should be carbohydrate and fat as the main source, and energy supply depends on the intensity of activity. Recuperating children can be supplied with 126 kJ to 147 kJ (30 kcal to 35 kcal)/kg body weight per day. 3, control the intake of sodium: severe edema and hypertension when sodium is limited to 60 ~ 120mg/kg. generally said that a gram of salt can retain 120ml of water, which will aggravate edema and hypertension salt does not affect nephritis, eating salt does not aggravate the kidney lesions, so when the kidney function gradually restored, urine volume increased, you can lift the salt withdrawal. Long-term salt withdrawal food is light and tasteless, affecting the appetite of children, thus causing malnutrition, and in severe cases, hyponatremia. Can salt substitutes, or “autumn stones”, be used during salt withdrawal? The principle is unnecessary: salt substitutes or “alkaline autumn stone” are actually potassium salts, and when there is renal insufficiency, there is often hyperkalemia, so consuming potassium salts will undoubtedly add insult to injury and aggravate hyperkalemia. 4, eat more fiber-rich food, the smooth flow of stool, detoxification is beneficial. Third, physical exercise: according to their own specific circumstances to choose moderate exercise to make the blood flow, to carry out some soothing movements, simple and easy physical exercise, to enhance physical fitness, such as walking. British doctors in a regular exercise study involving patients with kidney disease found that six months of regular walking (30 minutes / day, 5 times / week) of kidney disease patients with immune cell activation and systemic inflammation occurred significantly lower compared to patients who additionally did not increase the level of regular activity at the same time. This result suggests that moderate exercise has an anti-inflammatory effect in patients with kidney disease and may reduce the risk of cardiovascular disease in this way.
