My husband had the same surgery almost 2 years ago. He still has diarrhea or very soft or loose stools. His pancreatic enzime levels are still good so he does not take supplemental enzimes. They gave him some but they made him sick and did not do anything for the diarrhea. It comes from taking so much of the duodenum and stomach. His food does not have time to fully digest before passing thru. He takes imodium all the time to try to slow down his digestion to give it time for his body to try to absorbe nutrients. Nothing seems to work and the Drs. don't have any answers. My husband is dying from starvation and he eats very good all day long. It's like an anorexic person. His organs will fail before the cancer gets him. This is a problem for anyone who has a whipple procedure for pancreatic cancer. There really needs to be more studies done on this problem so pancreatic cancer patients can have a better chance of survival.
