The precautions for glomerulonephritis include the following: First, attention needs to be paid to monitoring the condition, mainly urine protein, especially if the onset manifests as nephrotic syndrome. The 24-hour urine protein quantification should be checked at any time before and after the medication and during the medication process to monitor the changes in the condition and the effect of treatment. The second is to prevent various infections, including oral, respiratory, gastrointestinal, urinary tract and skin infections, because infections may lead to recurrence or aggravation of glomerulonephritis. Monitor urine output and blood pressure. Fourth, a light diet, low sodium diet, 24-hour sodium intake is controlled below 5g, especially for patients with edema and difficult to control hypertension. V. Patients with glomerulonephritis should take rest and exercise appropriately.
