Hello dear Understand your concern Following are the cause of protein in urine: Diabetic nephrosclerosis , hypertensive neprhrosclerosis: in which glomerulo=us basement membrane will damage and increase its permeability lead to protein in to the urine. Other causes are: Overflow proteinuria in which increased protein in serum and then appear into the urine like multiple myleoma, high grade fever, Nephrotic syndrome, amyloidosis, excessive stress and strenous exercise etc. As you have strong history of diabetes in the family, it may be early sign of diabetes. I advice you to consult the MD physician or nephrologist to confirm the diagnosis. Get the following test done: blood sugar, USG, Hb1Ac, urinary microprotein test, UACR (Urine albumin creatinine ratio), lipid profile, blood pressor check up, serum protein, uric acid. Management depends on the cause of problem. Do regular exercise, avoid excessive sweets, take small frequent meal, doctor may provide losartan for proteinuria. Hope this may help you Best regards Dr. Sagar
