HIATL2
What is Hiatal Hernia?
A hiatal hernia occurs when part of the stomach pushes through an opening in the diaphragm, the muscle separating the chest from the abdomen. This opening, called the esophageal hiatus, normally allows the esophagus to pass through it to connect with the stomach.
Types of Hiatal Hernias
There are two main types of hiatal hernias:
- Sliding hernia: This is the most common type, where the stomach slides up into the chest through the esophageal hiatus.
- Paraesophageal hernia: In this case, the stomach remains in its normal position, but a portion of the esophagus or other abdominal organs push up through the hiatus alongside the stomach.
Associated Diseases
Hiatal hernias are often associated with gastroesophageal reflux disease (GERD), a condition in which stomach acid flows back into the esophagus, causing heartburn and other symptoms. Other associated diseases include:
- Acid reflux
- Difficulty swallowing (dysphagia)
- Chest pain
- Nausea and vomiting
Did you Know ?
Approximately 20% of the population has a hiatal hernia, with the risk increasing with age. By the age of 50, about half of all adults have some degree of hiatal hernia.
