What causes high Creatinine and low Vitamin B12?

High Creatinine and low Vitamin B12 can be caused by many reasons.

If your Creatinine is in between 0.9 mg/dL and 1.3 mg/dL and your Vitamin B12 is in between 211 pg/mL and 911 pg/mL then you need not worry as these are the normal ranges for Creatinine and Vitamin B12 respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Some examples of conditions that can increase or decrease creatinine levels include:

• Damage to or swelling of blood vessels in the kidneys.
• Bacterial infection of the kidneys (pyelonephritis)
• Conditions that can block the flow of urine in the urinary tract, such as prostate disease or kidney stone
• Reduced blood flow to the kidney due to shock, dehydration, congestive heart failure, atherosclerosis, or complications of diabetes
