The condition of acute nephritis is generally quite severe. Patients may experience hematuria and proteinuria, with diffuse cellular proliferation in the glomeruli. However, this disease is self-limiting, and the condition can heal on its own. It is important to control the causes of acute nephritis and the complications it may cause to help patients overcome the difficulties. Afterward, the patients' hematuria and proteinuria could potentially disappear. Generally, it takes about 3 to 4 weeks for the urinalysis to turn negative, and some patients may even take up to six months to recover. If recovery takes more than six months, it is possible that the patient's acute nephritis has become chronic nephritis.
