What role does overeating play in a gallbladder attack?

Overeating can stimulate the gallbladder to squeeze but so does even a small amount of fat so it's more the fats in the food than it is overeating. But usually if we're overeating it's usually something very, very rich. It's usually something greasy, pizzas, fried chicken, so they go hand-in-hand. But once again, anything can make that gallbladder squeeze down and give you a gallbladder attack.
