Understanding Hiatus Hernia A hiatus hernia is a condition in which the upper part of the stomach bulges up through the diaphragm, a large muscle that separates the abdomen from the chest. The esophagus, or food pipe, passes through an opening in the diaphragm called the hiatus. In a hiatus hernia, the stomach pushes through this opening. Types of Hiatus Hernia There are two main types: 1. Sliding Hiatus Hernia:** This is the most common type, where the stomach and the lower part of the esophagus slide up into the chest through the hiatus. This type often moves in and out of the chest. 2. **Paraesophageal Hiatus Hernia:** This is less common and more concerning. In this type, a portion of the stomach pushes up through the diaphragm alongside the esophagus and stays there. This can lead to the stomach becoming trapped, restricting blood flow, and potentially causing a medical emergency. **Causes and Symptoms** The exact cause of hiatus hernia is not always clear, but it is often associated with increased pressure in the abdomen, which can be caused by coughing, vomiting, straining during a bowel movement, or heavy lifting. Other risk factors include obesity, aging, and a congenital (present at birth) large hiatus. Many people with a sliding hiatus hernia experience no symptoms. However, when symptoms do occur, they are often related to gastroesophageal reflux disease (GERD), including: * Heartburn * Regurgitation of food or sour liquid into the mouth * Difficulty swallowing * Chest pain or abdominal pain * Belching **Diagnosis and Treatment** A hiatus hernia is typically diagnosed through an X-ray, endoscopy, or a barium swallow. Treatment for a hiatus hernia without symptoms is usually not necessary. For those with symptoms, treatment focuses on managing GERD. This can include lifestyle modifications such as eating smaller meals, avoiding trigger foods, and elevating the head of the bed. Medications, such as antacids or proton pump inhibitors, may also be prescribed. In rare cases, surgery may be required to repair the hernia, particularly with a paraesophageal hernia or when symptoms are severe and do not respond to other treatments.
