Acute nephritis is a kind of disease that has the tendency of self-healing and generally does not affect the life expectancy of patients, while a small number of them may become chronic and even lead to uremia. Acute nephritis, also known as acute glomerulonephritis, can be fully recovered after bed rest and symptomatic treatment, without any sequelae, and will not affect the life expectancy, so the life expectancy of this part of patients with acute nephritis is comparable to that of normal people. However, a very small number of patients with acute nephritis have life-threatening complications, such as acute renal failure, severe infections, etc. A small number of patients with acute nephritis will be left with chronic renal injury, and even progress to uremia, which will also affect the life expectancy of the patients, but it usually takes several decades from the onset of acute nephritis to the death of the patients. When acute nephritis occurs, it is recommended to consult a doctor in time and treat it actively under the guidance of a physician.
