A hiatal hernia occurs when a portion of the stomach protrudes upward through the diaphragm, the large muscle separating the chest cavity from the abdomen. This shift happens at the esophageal hiatus, the opening where the esophagus connects with the stomach. While many small hernias cause no noticeable symptoms, larger ones frequently impair the function of the lower esophageal sphincter. This impairment often leads to the backflow of stomach acid into the esophagus, a condition known as gastroesophageal reflux disease (GERD). Managing this condition involves a sequential medical approach utilizing different specialists based on the severity and complexity of the symptoms.
Starting the Journey: Primary Care and Initial Screening
The initial encounter for symptoms suggesting a hiatal hernia typically begins with a Primary Care Physician (PCP). Patients often present with complaints like recurring heartburn, regurgitation of food or sour liquid, and persistent chest discomfort. The PCP takes a detailed patient history to understand the nature of the symptoms, differentiating them from other potential issues like cardiac pain.
Conservative management is the initial focus, centered on lifestyle modifications to alleviate reflux. The doctor recommends changes such as elevating the head of the bed during sleep and avoiding meals close to bedtime. Dietary adjustments, including limiting trigger foods like caffeine, alcohol, and high-fat items, are also advised.
If lifestyle changes are insufficient, the PCP initiates pharmacological treatment. This usually starts with acid-suppressing medications, such as H2-receptor blockers or proton pump inhibitors (PPIs). If symptoms persist despite a trial of optimized medical therapy, or if the initial diagnosis remains unclear, the PCP facilitates a referral to a digestive specialist.
Specialized Medical Management: The Role of the Gastroenterologist
When symptoms are severe, resistant to initial treatment, or involve complications, the patient is referred to a Gastroenterologist (GI), who specializes in disorders of the digestive tract. The GI specialist confirms the presence and type of hiatal hernia and assesses any damage to the esophagus using specialized diagnostic procedures.
Diagnostic Procedures
The most common diagnostic tool is an upper endoscopy (EGD), which allows the gastroenterologist to directly visualize the hernia size, check for inflammation (esophagitis), and identify serious changes such as Barrett’s esophagus. Another test is a barium swallow, or upper GI series, where the patient drinks a contrast liquid that coats the digestive tract, allowing the hernia’s anatomy and size to be clearly seen on X-ray imaging.
Functional Assessment
For a deeper understanding of functional issues, a GI specialist may order high-resolution manometry to measure the strength and coordination of the esophageal muscles during swallowing. They may also use a pH or impedance monitoring study to quantify the amount of reflux entering the esophagus. Based on these objective findings, the gastroenterologist adjusts the medical regimen, ensuring the patient is on the most appropriate combination and dosage of acid-suppressing medications. This specialist manages the long-term, non-surgical treatment plan, including surveillance for pre-cancerous changes in the esophageal lining.
When Surgery is Needed: Consulting a General or Thoracic Surgeon
For a minority of patients, medical management fails to control severe symptoms, or the hernia poses a risk of complication, necessitating a surgical consultation. This referral is made to a General Surgeon specializing in foregut surgery, or a Thoracic Surgeon in more complex cases. Surgery is indicated for persistent, severe GERD symptoms that significantly impair quality of life despite maximal medical therapy.
Surgery is also required for symptomatic paraesophageal hernias, which carry a higher risk of serious complications. These risks include obstruction, internal bleeding, or strangulation, where the blood supply to the herniated tissue is cut off. The surgeon’s goal is to return the stomach to its proper position below the diaphragm and tighten the enlarged opening.
The most common procedure is a laparoscopic Nissen fundoplication, a minimally invasive technique. The surgeon wraps the upper part of the stomach around the lower esophagus, creating a tighter valve (hiatoplasty) to prevent reflux while repairing the defect in the diaphragm. The surgical specialist evaluates the patient’s overall health and anatomical details to determine the most effective and safest surgical approach.
