Whether the progression of IgA nephropathy stage 3 can be controlled is related to factors such as the severity of the disease and the response to treatment. If the patient’s condition is mild and the treatment effect is good, the progression of the disease can be controlled after active treatment; if the patient’s condition is severe and the treatment effect is poor, the progression of the disease may not be controlled. Stage 3 IgA nephropathy, suggesting diffuse thylakoid proliferation and mild damage to the renal tubules, causing symptoms such as hematuria, edema, proteinuria, and high blood pressure, can be treated with hormonal medications and immune preparations under the guidance of a doctor, such as prednisone and cyclophosphamide, etc. If the patient’s condition is mild, the individual’s physical condition may not be able to control the progression of the disease. If the patient’s condition is mild and his physical condition is good, the progression of kidney disease can be controlled or delayed after active treatment; if the patient’s condition is severe and his physical condition is poor, the treatment effect is not good and the progression of the disease may not be controlled at this time. Patients with IgA nephropathy stage 3 are recommended to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
