Gallbladder Removal

Does anyone know what the likelihood of gallbladder issues is post-sleeve? I know that it is fairly common for people to have problems with their gallbladders after going on extremely low-fat diets. My sister, my mother-in-law, and my sister's sister-in-law all had to have their gallbladders removed as a result of eating extremely low-fat diets at one time or another. I also remember reading that people who used Nutrisystem in the 90's often had to have their gallbladders out, because back then their food was extremely low-fat.

I just received my post-op diet plan and it includes a lot of "low-fat" this and "low-fat" that. It specifically says to avoid things like cheese, white dressings and sauces, butter, oil, mayo, cream, etc. even once I am back to solid foods. Not to mention the fact that with the physical restriction on how much we can eat and the emphasis on getting all our Protein in, it doesn't leave much room for fat in our diets anyway.

Has anyone experienced any gallbladder issues post-op or read any studies about the chances of gallbladder complications after VSG?
