<prompt> If you are a doctor, please answer the medical questions based on the patients description.my dad is having increase in creatine level upto 2.00 while the normal is upto1.4 now from last 3days he is taking medicines cepodem 325 and nutrolin-bplus but is having mild fever from around 99-100 from last 15 days he is also having weight loss more ever he has taken 5 days antibiotics beforethese 3days but worry is regarding stable fever  <response>: Hello there, Raised creatine levels can be a consequence of fever itself, so they singularly are not a worrying factor. A fever may indicate an undetected underlying infection. Since you did not mention your fathers age a urinary tract infection is fairly common in men above 55-60 years of age especially if they have a benign prostate enlargement which happens to men when they are that age. I would advise you to get his urine tested and cultured andor getting an ultrasound abdomen to evaluate any bladder disturbances. Thank you for your query, Chat Doctor.
