What is hiatal hernia?

When an organ or tissue leaves or travels abnormally from its position, a hernia occurs. On the diaphragm, which separates the chest cavity from the abdomen, the hiatus is identified. Therefore, the term hiatal hernia is used to describe the condition in which the stomach appears to protrude into the hiatal opening beyond the abdominal cavity. The food pipe or esophagus travels and links to the stomach during the hiatus. When the upper portion of the stomach begins jutting out of this opening, a hiatal hernia occurs.

The risk of hiatal hernia at an increasing age and often in the 50s. Smoking and obesity also increase the risk of a hiatal hernia.
