Hiatal hernia
A hiatal herniation is an unpleasant condition that sees the upper stomach bulge through the muscle that separates it from the chest.
Doctors also know that the muscle, the diaphragm, as the hiatus and the hernia pushes the stomach upwards.
Usually, they don’t cause pronounced issues, but a growing hernia can push food and acid back into the oesophagus.
