Increased creatinine levels in the blood suggest diseases that affect kidney function. These can include:
glomerulonephritis (swelling of the kidney’s blood vessels);
pyelonephritis (pus-forming infection of the kidneys);
acute tubular necrosis (death of cells in the kidneys’ small tubes);
urinary tract obstruction; or
reduced blood flow to the kidney due to shock, dehydration, congestive heart failure, atherosclerosis, or complications of diabetes.
Creatinine can also increase as a result of muscle injury. In general, creatinine levels will stay the same if you eat a normal diet. However, eating large amounts of meat may cause short-lived increases in blood creatinine levels. Taking creatine supplements may also increase creatinine.

High BUN levels suggest impaired kidney function. This may be due to acute or chronic kidney disease. However, there are many things besides kidney disease that can affect BUN levels such as decreased blood flow to the kidneys as in congestive heart failure, shock, stress, recent heart attack or severe burns; conditions that cause obstruction of urine flow; or dehydration.
BUN levels increase with age and also with the amount of protein in your diet. High-protein diets may cause abnormally high BUN levels. Drugs that impair kidney function may increase BUN levels. Your BUN and creatinine may be monitored if you are on certain drugs.
