Hiatal Hernia And Its Relation to Acid Reflux
A comprehensive guide to hiatal hernia: how it occurs, its relation to heartburn and chronic reflux, and when it needs surgical treatment.
In this article
Hiatal hernia is a special type of hernia differing from the usual abdominal wall hernia, occurring when part of the stomach pushes upward through an opening in the diaphragm into the chest cavity. It's among the most overlooked causes of heartburn and chronic reflux that many suffer from without knowing its real cause. Understanding this relationship may explain long suffering. Hiatal hernia treatment is part of laparoscopic surgery, and relates to understanding what is a hernia generally.
What Is a Hiatal Hernia?
The diaphragm is a large muscle separating the chest cavity from the abdominal cavity, with a natural opening through which the oesophagus passes to reach the stomach. In hiatal hernia, this opening widens so part of the stomach pushes upward through it into the chest. This change in anatomy weakens the natural valve that prevents the return of acidic stomach content to the oesophagus, so reflux occurs. The hernia's size ranges from very small causing no symptoms, to large causing bothersome and persistent symptoms.
The Relation of Hiatal Hernia to Reflux and Heartburn
Heartburn
A burning sensation behind the breastbone, increasing after eating and lying down, among the most common symptoms.
Acid Reflux
Return of acidic stomach content to the oesophagus and throat, with a bitter or sour taste in the mouth.
Difficulty Swallowing
A feeling that food is stuck, or difficulty swallowing with a large hernia.
Unexpected Symptoms
Chronic cough, hoarseness, or chest pain that may be confused with other diseases.
Why Is Hiatal Hernia Diagnosis Overlooked?
Many chronic reflux patients take acid medications for years without anyone knowing the root cause may be a hiatal hernia. The reason is that symptoms (heartburn, reflux) are treated as an independent entity without searching for their anatomical cause. Sometimes symptoms are atypical (cough, hoarseness, chest pain) directing diagnosis to other directions like heart or lung disease. So a patient suffering chronic reflux resistant to medication deserves evaluation to search for hiatal hernia as a possible cause.
If you suffer chronic heartburn and reflux despite medication, don't settle for treating symptoms. Search for the root cause, which may be a hiatal hernia. Correct evaluation may offer a definitive solution instead of permanent reliance on acid medications.
Treatment of Hiatal Hernia
Treatment of hiatal hernia depends on its size and symptom severity. A small hernia with few symptoms is often managed with lifestyle changes (avoiding large meals and lying down after eating, raising the head during sleep, weight loss) and acid-reducing medications. A large hernia or chronic symptoms resistant to medication may need surgical repair. Modern surgery is performed laparoscopically, where the stomach part is returned to its place, the diaphragm opening is narrowed, and the valve is strengthened to prevent reflux. Learn about the advantages of modern laparoscopic surgery. Results are excellent in easing symptoms and improving quality of life.
"Many chronic reflux patients suffer for years on acid medications without knowing hiatal hernia is the cause. When we repair the hernia laparoscopically, long suffering often disappears. Searching for the root cause is the key to the real solution."
Dr. Mohamed EsmatFrequently Asked Questions
Is a hiatal hernia dangerous?
A small hernia is often not dangerous but bothersome with reflux. A large hernia may need treatment to avoid complications. The doctor assesses your case.
Is all reflux caused by hiatal hernia?
No, reflux has multiple causes, but hiatal hernia is among the most overlooked. Chronic reflux resistant to medication deserves searching for a hiatal hernia.
Can a hiatal hernia be treated laparoscopically?
Yes, modern hiatal hernia surgery is performed laparoscopically with excellent results in easing symptoms and faster recovery than open surgery.
