Urine microalbumin 0.15g refers to 150mg per liter of microalbumin in urine, which exceeds the normal range of 20mg per liter. Generally, urine protein abnormalities can be caused by physiological and pathological factors. Physiological factors such as strenuous exercise, consuming too much meat, etc., usually after the elimination of the triggering factors, the urine protein can return to normal. Pathologic factors such as glomerulonephritis, diabetic nephropathy and so on. It may also be related to diet, etc. Patients are advised to go to regular hospitals for a comprehensive examination. 1. Glomerulonephritis: Glomerulonephritis damages the protein filtration function, which leads to a sharp increase in the protein content in the urine, i.e. the symptom of proteinuria. Patients need to control blood pressure and protein intake to control the content of microalbumin. 2. Diabetic nephropathy: diabetic patients are in a state of high blood sugar for a long time, resulting in renal vascular lesions. Patients can control blood sugar and improve dietary habits to relieve the pressure of kidney functioning, thus relieving the pressure of protein production. It is recommended that patients with abnormal urinary microalbumin go to the hospital in a timely manner, under the guidance of the doctor to improve the relevant examinations, such as pathological factors should be actively treated to avoid delays in the condition.
