So my mom has pancreatic cancer, she got whipple surgery done almost a year ago. They removed her gallbladder along with much of her digestive system. Since then her weight has been plummeting. and the fact that her stomach is much smaller makes it even harder for her to keep her weight up.Our solution is obviously to have her eat the most high calorie foods possible, which means a high fat diet. (fat has twice the calories as carbs or protein). But Im thinking this might be the wrong idea, because with no gallbladder, wont most (or all) of the fat go undigested? Shes trying to gain weight and her body could be reacting like its taking Orlistat diet pills.Im worried that Steatorrhea may be causing her to lose too much weight, and that a high fat diet is actually harmful to her health? any advice would be appreciated! Thanks.

Hi and welcome to Chat Doctor. Thank you for your quarry. Whipple procedure is major surgical procedure and it always case digestion disorders because art of stomach and small intestine is removed, and pancreatic secretion is disturbed. Gallbladder removal is not problem at all. People have normal fat absorption after this because bile is secreted from the liver and the is no effect on digestion after gallbladder removal. Although, she should have more but smaller meals at least 6-7 times per day. It should be easier food, but you shouldn't avoid healthy fats and meat. She needs more nutrients than before surgery so try to make her diet various with 60% carboy Chat Doctor.  Also, she should take vitamins supplements. There are certain shakes which can be useful for weight gaining so ask you GP about it. Wish you good health.
