Explain Presence of Foodstuffs - Movements of Gall Bladder
Presence of foodstuffs: Fatty foods particularly cream, fatty acids and proteins to a less extent, stimulate the contraction of gall bladder. Bile is expelled from the gall bladder when these foodstuffs are eaten. Fatty meal is given to the patient to examine gall bladder movements during X-ray of gall bladder (referred to as cholecystography).
