In brief: Stretched diaphragm

There is normally a hole in the diaphragm through which passes the esophagus.
The diaphragm separates the abdominal and chest cavities, and the chest cavity is like a vacuum. When the normal opening stretches out and becomes large enough, the stomach gets "sucked" into the chest slowly. Why some get this and others don't is largely a mystery.
