Hi and welcome to HCm. Thank you for your querry.
Whipple procedure is major surgical porcedure and it always casue 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 aftet this because bile is secreted from the liver
and ther is no effect on disgestion 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 shouldnt avoid healthy fats and meat. She needs more nutritents than before surgery so try to make her diet various with 60% carbohydrates,20 prteins and 20 fats. 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.
