If we eat too much at once why might we feel sick or have a stomach ache?

Eating too much at once can lead to a stomach ache because it puts excessive pressure on the stomach, which can stretch beyond its comfortable capacity. This overdistension can trigger discomfort and pain as the body struggles to digest the large volume of food. Additionally, overeating can cause the digestive system to work harder, potentially leading to issues like acid reflux or indigestion. The release of hormones in response to a heavy meal can also result in feelings of nausea.
