Gallbladder disease: If you don’t eat breakfast, it is easy to lead to the concentration and storage of bile in the gallbladder, which will form cholesterol crystals over time, causing stimulation of the gallbladder, which is easy to form cholecystitis and easy to lead to gallbladder stones and gallbladder polyps. 3.
