Hiatal hernia is a condition in which the upper part of your stomach bulges through an opening in your diaphragm. Your diaphragm is the thin muscle that separates your chest cavity from your abdominal cavity.

It separates your thoracic cavity (which houses your lungs and heart) from your abdominal cavity (which houses your stomach and other digestive organs).

The esophagus passes through an opening in the diaphragm called the diaphragmatic hiatus before it attaches to the stomach.

If there is a weakening in your diaphragm in the area of the hiatus (where the esophagus passes through), your stomach may be able to partially slip through the diaphragm into the chest cavity, forming what is known as a sliding hiatal hernia. Normally, the diaphragm contracts and helps to strengthen the lower esophageal sphincter when you bend, cough, or strain. When you have a hiatal hernia; however, bending, coughing and straining can make symptoms or acid reflux worse.
