HIATL1
Hiatal Hernia: A Common Yet Misunderstood Condition
Description
A hiatal hernia occurs when a portion of the stomach protrudes through an opening in the diaphragm, the muscle separating the chest and abdomen. Normally, the diaphragm has a small opening called the esophageal hiatus, through which the esophagus passes from the chest into the abdomen. In a hiatal hernia, this opening widens, allowing part of the stomach to push through.
There are two main types of hiatal hernias:
- Sliding hernia: The most common type, where the stomach slides up through the esophageal hiatus.
- Paraesophageal hernia: A less common and more serious type, where the stomach pushes up alongside the esophagus, creating a bulge beside it.
Associated Diseases
Hiatal hernias can be associated with other digestive conditions, such as:
- Gastroesophageal reflux disease (GERD): A condition where stomach acid flows back into the esophagus.
- Esophagitis: Inflammation of the esophagus.
- Barrett's esophagus: A precancerous condition where the lining of the esophagus changes.
