Normally, the esophagus passes down through the chest, crosses the diaphragm,
and enters the abdomen through a hole in the diaphragm called the esophageal
hiatus. Just below the diaphragm, the esophagus joins the stomach. In
individuals with hiatal hernias, the opening of the esophageal hiatus
is larger than normal, which allows a portion of the upper stomach to
protrude through the hiatus and into the chest.
The two main types of hiatal hernias include:
Sliding Hiatal Hernia is the most common type of hiatal hernia, in which part of the stomach
slides into and out of the chest cavity. This may occur because of weakening
of the anchors of the esophagus to the diaphragm, from years of longitudinal
esophageal muscle contractions, or from increased pressure in the abdomen.
Paraesophageal Hernia occurs when part of the stomach squeezes through the hiatus, placing it
next to the esophagus. Unlike sliding hernias, paraesophageal hernias
remain in the chest at all times. This type of hernia is less common,
but can be dangerous because the stomach may become "strangled,"
which means its blood supply is cut off.
Risk Factors for Hiatal Hernia
Hiatal hernias are more common in adults over 50 years of age.
Other factors that increase your chance of getting hiatal hernia include:
- Abdominal injury or sudden physical exertion (such as weight lifting)
- Regular increased pressure in the abdomen from activities like severe coughing,
vomiting and straining during bowel movements
Symptoms of Hiatal Hernia
Most people with hiatal hernias have no symptoms. However, a hiatal hernia
can lead to stomach acid moving up into the esophagus. This is known as
gastroesophageal reflux disease (GERD).
Symptoms of GERD can include:
Heartburn, especially after eating or lying down
Dysphagia (difficulty swallowing)
- Pain or discomfort in the stomach, chest, or esophagus
- Frequent clearing of the throat from irritation
- Chest pain
Because hiatal hernia symptoms are similar to many other esophageal conditions,
accurate evaluation is critical to ensure proper treatment. That’s
why it’s important to seek care from a healthcare expert experienced
in the complex
treatment of esophageal disorders and other related conditions.
