How is obesity related to developing gallstones?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Your gallbladder may seem as unnecessary as red-carpet specials, but one of its functions is to help store bile—that digestive juice that helps your body absorb nutrients. Obese people have a greater than 50 percent chance of developing gallstones. Why? An overworked liver caused by being overweight makes more stone-forming bile. Bile in obese people is more like sludge than liquid, which predisposes them to developing stones.

It's also more likely that you'll develop stones when you lose weight quickly, like after weight-loss surgery (because the gallbladder doesn't empty enough when it doesn't see any fat). So it's not uncommon for surgeons to remove gallbladders during gastric bypass procedures.
