Veteran RNY ers ( or others ) do you still have malbsorption and volume restriction years...

I find I still malabsorb fats nine years or so post op - ( sorry to be graphic) - my poo comes out soft and very light yellow in color the next day ( sometimes urgently ) if say I eat full fat cheese or a restaurant meal which contain usually several times the amount of fats and oils I?d ever consider using at home .

My ex husband who had a distal RNY said the same thing ( he was operated on a few years before me ).
He also still has significant restriction- he always has to bring most of his restaurant meals home like I do .

I?m just very curious- what makes our bodies keep this gift and if we have it why do many folks significantly regain after the two year honeymoon period ?

Since my surgery I?ve made it a point not to overeat ( not that I can ) nor to test ? dumping ? by eating sugar or say fried or most fast foods .

what is your experience?
