I had my gallbladder removed 6 months ago…I do not have weight gain issues, although I have other complications. I too have diarrhea BADLY…every morning about 3-4 times within an hour of waking up, my food also “rushes” through my system forcing me to find a bathroom ASAP after I eat. AVOID FAT AND RICH FOODS… THIS WORSENS THE RIGHT SIDE PAINS, AND LOOSE STOOLS. Also, I take 2 GAS-X pills everymorning now, this helps with gas and bloating. I also take a vegetable/fruit vitamin, once a day, that has 3 full servings of each in it…this helps allow stools to be more formed.
