Hi Akhil,
Thanks for using the HCM. I am happy to address your questions, the normal creatinine range for a man is 0.6-1.2 with a critical value being >4. Creatinine is used in skeletal
muscle contraction and is excreted entirely by the kidneys. There are slight increases in creatinine levels after meals, especially after eating large amounts of meat. Certain medications can increase your creatinine levels as can
diabetes, reduced renal blood flow (from CHF or
dehydration), or a
urinary tract obstruction. There are other conditions that can cause an elevated creatinine as well but you would be symptomatic with them. Also, simple dehydration can cause some elevation. Prolonged
high blood pressure, or
hypertension, is the most common cause of kidney damage, the worst is kidney failure. Try to control high blood pressure to prevent kidney disease, cardiac disease and stroke. It may be brought under control through exercise and diet (especially salt avoidance). It may need drug treatment. Your doctor can best guide you on this. If you improve blood pressure, the
serum creatinine may go down, but more importantly, it is less likely to go up, meaning your kidney function is less likely to worsen. Hope I have answered your query. If you have any further questions I will be happy to help. Thanks
