It is possible for a person to eat enough to burst his stomach, reports NBC News. A typical stomach holds between 1 and 4 liters of food before the body's natural gag reflex expels the excess material. However, some people ignore this reflex and consume enough to rupture the stomach.
Most cases of stomach ruptures occur when people attempt to stuff about 5 liters of food into their body, according to NBC News. The excess volume stretches the stomach wall until it tears, releasing the contents of the stomach into the body cavity. Surgical repair is necessary to fix a ruptured stomach lining. People affected by this typically have a significant history of unhealthy eating habits.
