<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have no diabetes or no high blood pressure and do a lot of walking. My microalbumin urine is 381mgl but my creatinine is 4.2mmoll. Do I have kidney disease? i am very active normally and but have been using simvastatin to control my cholesterol over last 2 years around 5.2mmoll. Thank you  <response>: Hello! Yes, your concern is very true. Raised creatinine level indicates either obstructive myopathy or Medico-renal disease i.e. obstruction to urine outflow or dysfunction of parenchymal functional tissue of kidneys. Obstruction can be due to many causes like stonesstricturesgrowths or pressure on urinary tubes uretersurethra from outside i.e. growths from surrounding structures like rectumuteruscolon etc. In my clinic, I advise X-ray PUB, ultrasound abdomen pelvis, urine routine, renal function tests, serum uric acid. Treatment is accordingly. Hope this information is useful to you. Wish you healthy life. Thanks. Regards.
