If you are vomiting it does. But usually food doesn't go back into the esophagus because it tends to go down hill, going back into the esophagus is going against gravity.
----------
Also, the lower esophageal sphincter normally prevents stomach contents from flowing backwards. Sphincters are rings of muscle that open and close to control the flow in various places in the body.

∙ 13y agoThe esophagus performs peristalsis, contraction of muscles to push food in a certain direction, in this case, toward the stomach. The stomach is also in a lower position from the esophagus , meaning that for food to get up, it would have to contend with gravity, and that the food is sitting t the bottom of the stomach, away from the exit of the esophagus. Also the esophagus has a valve that prevents food from moving out unless it needs it to.
