Most patients with acute glomerulonephritis show improvement in urinalysis within 4 weeks, and serum complement returns to normal within 8 weeks, a small number of patients with hematuria and urinary protein may delay for half a year to a year to recover, and a very small number of patients may be left with abnormal urinalysis and become chronic, and there are a small number of patients with chronic nephritis in the distant future after cure. Acute glomerulonephritis is a kind of disease that has the tendency of self-healing, which is induced by streptococcus and other infections. Acute glomerulonephritis patients are mainly manifested as hematuria, proteinuria, edema, high blood pressure, etc. After bed rest and symptomatic treatment, proteinuria will gradually return to normal in 4 weeks, and complement will return to normal in 8 weeks, while proteinuria and hematuria may be delayed for half a year to one year before disappearing completely in a small number of patients, and a small number of patients may even turn into chronic. It is recommended that patients with acute glomerulonephritis go to the hospital in time and take medication under the doctor’s guidance as soon as possible to avoid delaying the condition.
