Urine protein will be intermittent in the early stage of nephritis. Urine protein will be present at the beginning of nephritis because the glomeruli are destroyed in nephritis, and when blood passes through the glomeruli, it can not block the protein or red blood cells from entering into the urine, thus producing proteinuria or urinary occult blood. However, urine protein appears positive intermittently and it is not possible to determine if you have nephritis. If the urine protein appears after strenuous exercise, it is necessary to rest before examination. When patients have intermittent urine protein, if necessary, it is recommended that patients actively undergo renal puncture biopsy to clarify the renal lesions. It is also necessary to pay attention to low-salt, low-fat and high-quality protein diet, avoid eating spicy, greasy or other stimulating foods, regular and regular blood pressure measurement, and avoid the application of nephrotoxic drugs. Patients with nephritis are recommended to visit regular hospitals for standardized examination and treatment under the guidance of physicians.
