Q3. What is a hiatus hernia?

A3. A hiatus hernia forms when a section of the stomach pushes upwards through the diaphragm into the chest region. There is an opening within the diaphragm called the ‘hiatus’ (hence the name of the hernia) which the oesophagus (long tube which carries food from your mouth to the stomach) passes through.

But this opening can also be a weak spot which allows part of the stomach to push up and into the chest cavity.
