Hello, Thank you for your contact to healthcare magic. I understand your health concern, if I am your doctor I suggest you that raising creatinine level is always suggestive of kidney affection. Since you are hypertensive it has most probably affected your kidney, also there is chances of diuretic induced rise in crearinine. But whole history is necessary to diagnose the condition accurately. Kindly visit the nearby doctor and discuss with them the above mentioned description. I will be happy to answer all your future concern. Thank you, Dr Arun Tank Infectious disease specialist. Wish you a best health at health care magic.
