Normally, the diaphragm separates the chest cavity from the abdomen. A hernia occurs when a portion with the stomach forces its way up into a little opening within the diaphragm that will allow the esophagus to pass through, known as the hiatus. This is generally triggered when the muscles and tissue around the hiatus weaken. You will find 3 distinct forms of hiatal hernias: sliding, paraesophageal, and mixed. A sliding hernia is characterized by movement in the upper belly into the chest cavity to ensure that the valve that separates the belly and esophagus is forced up and above the diaphragm. This valve is known as the reduced esophageal sphincter, and it truly is in charge of preserving your abdominal acid or food from flowing back up into your esophagus.
