Early mild nephritis is partially curable, but it depends on the type of nephritis, that is, the pathological subtype of the kidney. Specifically, acute nephritis early mild can be cured, and about 2 weeks to a month of hospitalization can be discharged. But if it is chronic nephritis, even if the disease is relatively mild in the early stage, it is because of the presence of long-term immune factors, the kidneys will continue to be damaged, and any intervention with medication cannot make it curable, but can only make the condition relatively relieved, the kidney function will not deteriorate further, and the residual kidney function can be preserved, which is not curable in this case. For the criticality of nephritis, the assertion is not made in terms of early and mild stages, but in terms of the degree of kidney damage and the type of damage.
