Why does chocolate make you use the bathroom?

Chocolate can have a laxative effect for some people due to its caffeine and theobromine content, which can stimulate the digestive system. Additionally, certain types of chocolate, especially those high in sugar and fat, can lead to gastrointestinal discomfort or diarrhea in sensitive individuals. The presence of milk or dairy in some chocolate products may also contribute to digestive issues for those who are lactose intolerant.
