Why Do Some People Need to Use the Bathroom Right After Eating?

Many people have experienced the sudden urge to use the bathroom shortly after eating. For some, it happens only occasionally after a large meal, while for others it seems to occur almost every day. Although this experience can be surprising or even worrying, medical experts say that in many cases it is linked to a normal digestive response known as the gastrocolic reflex. Understanding how this process works can help people distinguish between normal digestion and signs that may require medical attention.
