Typically, after two to three weeks of treatment, the condition of most patients with acute nephritis can recover. However, if the condition of acute nephritis worsens, patients should return to bed rest and adopt different treatment methods based on their clinical symptoms.

If the patient presents with edema, it is essential to maintain a low-salt diet, with daily salt intake less than 2-3 grams. Additionally, the patient's blood pressure must be addressed. If there is a significant rise in blood pressure, it is advisable to start with a low dose of diuretics, which can facilitate urination, fluid excretion, and lower blood pressure. If blood pressure control is inadequate, calcium channel blockers should be considered.

Moreover, if a patient with acute nephritis develops acute renal failure, dialysis treatment may be necessary; similarly, if acute heart failure occurs, medications to control blood pressure and dilate blood vessels should be used to reduce the cardiac workload, thereby facilitating recovery from acute nephritis.

(Specific medications should be used under the guidance of a physician.)
