IgA nephropathy cannot be completely cured. IgA nephropathy is a type of chronic glomerulonephritis and is a chronic disease. Currently, it is incurable in medical practice. However, many patients have only mild symptoms, such as mild hematuria, proteinuria, and minor kidney damage, and timely long-term management of the disease usually does not lead to severe consequences. Some patients, on the other hand, have relatively severe conditions and require treatment with steroid medications. Most of these patients can achieve relatively good treatment outcomes and ultimately avoid severe kidney failure. However, a very small number of patients may eventually experience significant proteinuria and even severe renal failure.
