Same experience here with dietician giving printouts which I could have done myself.
The food they put on my plate also went against the instructions. What ??? I learned the hard way by getting 2 small bowel obstructions and sepsis. Very sick. I have found due to my anastomosis stricture I can only have liquids mostly but can try very mushy foods eg mashed potatoes and yes very, very small portions several times a day. Not 3 meals a day.A bite here,bite there and the foods must be under the easy to digest column. Therefore amount and kinds of food extremely important. The only thing I cant understand is I thought food was practically liquid by the time it go to large intestines so how is it backing up ? Anyone ?
