Acute glomerulonephritis, which is overwhelmingly caused by streptococcal infection, is a common disease in pediatrics. According to statistics, acute glomerulonephritis accounts for 53.7% of pediatric urologic disorders in the same period, and is more common between the ages of 5 and 14 years. In brief, acute glomerulonephritis is more frequent in pediatric and adolescent patients, but also occasionally in middle-aged and elderly people, and the incidence is higher in males than in females, with a ratio of about 2:1. Acute glomerulonephritis is particularly important in the early stages of its development, diet control! 1, low protein diet Protein intake should be determined according to the condition: patients with mild symptoms, daily protein intake should be controlled at 0.2 to 0.5g/kg to reduce the burden on the kidneys. However, a low-protein diet should be accompanied by high-quality protein to prevent anemia. When the blood urea nitrogen and creatinine clearance are close to normal, the protein supply should be gradually increased to 0.6~0.8g/kg per day to facilitate the repair of renal function. When selecting food, food with high quality protein containing more essential amino acids should be used first. For example, fish, poultry, lean meat, eggs and milk. Starch, sweet potatoes, potatoes, vermicelli and other foods with low protein content and high calorie content can also be used to replace some of the common rice and noodles to ensure sufficient energy. Patients need to determine the amount of protein intake according to the degree of renal impairment, if the disease is long and renal impairment is not serious, the protein in food does not need to be strictly limited, not more than 1g/kg per day can be, of which high-quality protein accounts for more than 50%. 2, adequate vitamins Acute glomerulonephritis groups are mostly young, however, the common problem of children is unwilling to eat fruits and vegetables. However, as a patient with acute glomerulonephritis, you must consume more fresh green leafy vegetables and fruits (Note: Vegetables and fruits need to be restricted during the oliguric period when potassium is restricted). Fruits and vegetables not only enhance appetite, but are also rich in many vitamins. Consumption of vitamin A, vitamin C, folic acid, B vitamins and iron, etc., are conducive to the recovery of kidney function and the prevention of anemia and other functions. 3.Limit potassium intake During the period of oliguria or anuria, we should strictly control the supply of potassium and avoid foods with high potassium content, such as fresh mushrooms, shiitake mushrooms, red dates, shellfish, beans, vegetables and fruits. However, we inevitably need to eat foods with high potassium content such as fruits and vegetables, so we should effectively reduce the potassium content of the food we eat. 4.Limit sodium and water In the early stage of the disease, the kidneys cannot excrete water in time, thus causing water and sodium retention, and most of the patients will have edema symptoms. Therefore, limiting water consumption and avoiding salt is a good way to eliminate edema. Patients should be given a low salt, less salt or no salt diet according to their condition, urine volume and edema, and also have their blood potassium and sodium levels checked regularly. Less sodium diet: In addition to not adding salt or soy sauce, foods with high sodium content should also be avoided. Patients with acute glomerulonephritis should maintain a positive and optimistic attitude, pay attention to rest (bed rest should be taken within 2 weeks of the onset of the disease). Avoid strenuous activities (appropriate exercises such as indoor activities or outdoor walks should be performed only after edema subsides, urine volume increases, hematuria visible to the naked eye disappears, and blood pressure drops to normal). Pay attention to a balanced diet and do not eat spicy and stimulating, barbecued and greasy foods.
