Whether nephritis urinary protein 3+ is serious or not needs to be assessed comprehensively, such as the type of pathology and the effect of treatment. If the pathologic type is light, such as mild mesangial proliferative glomerulonephritis, the treatment effect is good, at this time may not be serious; if the pathologic type is heavy, such as mesangial capillary glomerulonephritis, the treatment effect is not good, with the development of the disease may progress to uremia, at this time more serious. Nephritis, or glomerulonephritis, can be seen in a variety of pathologic types. For example, mild thylakoid proliferative glomerulonephritis, microscopic lesion nephropathy, partial membranous nephropathy, etc., have a good response to hormones and cytotoxic drugs, and some patients may have a spontaneous recovery, which is usually not serious. If there is mesangial capillary glomerulonephritis, focal segmental glomerulosclerosis, etc., the treatment effect is not good, the renal function continues to be impaired, and with the development of the disease may progress to uremia, which is a more serious situation. If patients with nephritis have urinary protein 3+, it is recommended to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
