In most cases, acute nephritis is not difficult to treat because the disease itself is self-limiting, meaning that acute nephritis can heal naturally within about 3 to 4 weeks. However, acute nephritis can cause some complications, and in severe cases, it may lead to disability or death. Therefore, when patients with acute nephritis develop serious complications, treatment may be relatively difficult or complications such as pulmonary infections, heart failure, and acute renal failure may occur. But with appropriate treatment, most cases are hopeful to be controlled.
