Hi. Thanks for your query. Your history of Whipple s note. This is the reason for steatorrhoea. It looks that you have developed IBS thereby the action of Creon is not sufficient. You may have to take a tablet to reduce the motility and the problem may be solved. This may be the same reason you have pain in abdomen and the tests are so negative. Just get the following tests done to add on for a diagnosis. :::: Enteroclysis on a fluroscopy machine to see the motility , obstruction , kinking and related problems.
