Bladder Dysfunction

My friends tell me that protien shakes cause malfunction of the gallbladder? Is it true? Please need to hear an expert if you do not know do not write any bs here
Thank you

The gallbladder stores and secretes bile which is used to digest fats. When the gallbladder is full of gallstones or a stone is lodged in the bile duct, gall bladder can become dysfunctional. Gallstones are not stones at all, but are soft and rubbery. They are composed of bile salts and cholesterol. Protein has nothing to do with it.

Not the gallbladder is irritated by fatty foods. Over-consumption of protein shakes, without enough water can affect the kidneys, causing kidney stones in some people. But protein does not cause gallstones.
