Whether chronic nephritis is scary or not is related to factors such as the type of pathology and treatment effect. If the pathologic type is mild, the treatment effect is good and the disease is in remission, it is usually not scary; if the pathologic type is severe, the treatment effect is not good and the disease may progress to uremia, which is more scary. Chronic nephritis is characterized by proteinuria, hematuria, hypertension and edema as the basic clinical manifestations, with different ways of onset, prolonged and slow progression of the disease, with different degrees of renal function impairment, and some of the patients will eventually develop to uremia. In chronic nephritis with mild pathology, such as mild proliferative glomerulonephritis, partial IgA nephropathy, membranous nephropathy, etc., the treatment can make the urinary protein turn negative to achieve clinical cure, and the renal function is stable, and it may not be progressed to uremia, which is usually not scary at this time. While some patients with more serious pathologic types, such as focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, even after active treatment, renal function may still gradually decline, ultimately leading to uremia, which is more terrible at this time. Patients with chronic nephritis are advised to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
