Patients with glomerulonephritis without hyperkalemia can take potassium citrate granules. But need to follow the doctor’s advice to take. Glomerulonephritis is a more common kidney disease, acute glomerulonephritis occurs more often in children, streptococcal infection is the main cause of acute nephritis in children; chronic glomerulonephritis has different etiology, pathogenesis and pathological types, but the starting factor is mostly immune-mediated inflammation, mainly in young and middle-aged people, and more common in men. In patients with nephritis, the diet should be based on low-protein, low-phosphorus and vitamin- and iron-rich foods such as fish, beans, whole grains, fresh fruits and vegetables, and poultry, as well as limiting sodium intake and paying attention to potassium ion monitoring. Potassium citrate granules are used for the treatment of hypokalemia caused by various reasons, such as insufficient food, vomiting, severe diarrhea, the application of potassium diuretic, hypokalemic familial periodic paralysis, long-term application of glucocorticosteroids and supplementation of hypertonic glucose, etc.; also used for the prevention of hypokalemia, when the patient has a situation of loss of potassium, potassium needs to be supplemented as a precautionary measure. Potassium ions contained inside Potassium Citrate Granules can help patients with glomerulonephritis to supplement potassium. Patients with glomerulonephritis can take potassium citrate granules as prescribed by doctor if they do not have hyperkalemia, or when there is hypokalemia and long-term application of glucocorticoid. It is recommended that patients with glomerulonephritis should go to regular hospitals in time and take medication under the guidance of physicians.
