Whether proteinuria will heal on its own depends on its cause and the severity of the proteinuria. If proteinuria is caused by mental stress, severe cold or heat, strong physical labor, after eating a high-protein diet or prolonged standing, it usually belongs to physiological proteinuria, and generally proteinuria can heal itself after these factors are removed. However, for proteinuria caused by pathological factors such as various glomerular and tubulointerstitial diseases, hereditary nephropathy, renal vascular diseases and other kidney diseases, it usually does not heal on its own and needs to be treated accordingly. If it is caused by kidney stones or urinary stones, physical lithotripsy treatment is required. If it is caused by a urinary tract infection, taking antibiotics will improve in about a week or so. If the patient has proteinuria accompanied by other symptoms such as high blood pressure, swelling, frequent urination, urinary urgency, loss of appetite, and weakness, it is important to pay attention to it and actively seek medical attention for diagnosis and treatment.
