Hiatal Hernia

Hiatal hernias occur when a portion of the stomach pushes through the diaphragm into the chest cavity. The diaphragm is a muscle that separates the chest and abdominal cavities, and it has an opening called the hiatus through which the esophagus passes. Hiatal hernias are typically classified into two types: sliding hiatal hernias and paraesophageal hiatal hernias. Sliding hiatal hernias are the most common and occur when the junction where the esophagus meets the stomach and a portion of the stomach slide up into the chest. Paraesophageal hiatal hernias are less common but can be more serious as they involve a portion of the stomach squeezing through the hiatus alongside the esophagus.

The exact cause of hiatal hernias is often unknown, but certain factors can increase the risk. These include obesity, aging, frequent heavy lifting, pregnancy, and persistent pressure on the abdomen due to chronic coughing. Some hiatal hernias do not cause any symptoms and may be incidentally discovered during medical evaluations for other conditions. However, larger hiatal hernias can lead to symptoms such as heartburn, regurgitation, chest pain, difficulty swallowing, and a feeling of fullness after meals.

Treatment options for hiatal hernias depend on the severity of symptoms and the risk of complications. Lifestyle modifications such as maintaining a healthy weight, elevating the head of the bed, and avoiding trigger foods can help alleviate symptoms. Medications may be prescribed to reduce acid reflux and relieve heartburn. In more severe cases or when complications arise, surgery may be recommended to repair the hernia and strengthen the diaphragm. It is important for individuals with hiatal hernias to work closely with their healthcare provider to determine the best course of treatment based on their specific condition and symptoms.
