I just recently had a blood test when I went to the doctor after I threw out my back during a nasty bout of the stomach flu. I have been on Cipro for the past month or so for a pesky case of prostatitis too. My lipase came back 74 (normal is 0-50) and my ALT came back 87 (normal 0-50). I've had fluctuating ALT my whole life (presumably from all the medications I've had to take) but am now wondering if IBS has something to do with those levels as well. Perhaps the Cipro is irritating my IBS? I appreciate any help and/or advice regarding this.
