Hiatal Hernia on X-Ray
Part of the stomach protruding through the diaphragm into the chest
A hiatal hernia means part of the stomach has moved through the diaphragm into the chest, sometimes creating a retrocardiac air-fluid level on imaging.
A hiatal hernia happens when part of the stomach pushes upward through the opening in the diaphragm. Some are small and incidental, while others can contribute to reflux or chest discomfort.

What it is
- This is a structural condition involving herniation of part of the stomach through the diaphragmatic hiatus
- Sliding hiatal hernias are the most common type
How it appears on chest X-ray
- On chest X-ray, a hiatal hernia may appear as a retrocardiac air-fluid level or rounded lucent structure behind the heart
What radiologists look for
- Radiologists look for the location and size of the hernia, whether there is a clear air-fluid level, and whether additional upper GI imaging or CT is needed
How X-ray helps
- X-ray can suggest the diagnosis by showing a retrocardiac air-fluid level, though other imaging may define it more clearly
Causes
- Causes include laxity of the hiatus, increased abdominal pressure, age-related tissue change, obesity, and other factors that promote herniation
Symptoms
- Symptoms can include reflux, heartburn, chest discomfort, regurgitation, swallowing symptoms, or no symptoms if the hernia is small
Risk factors
- Risk factors include older age, obesity, pregnancy, chronic straining, and increased abdominal pressure states
Complications
- Complications can include reflux symptoms, esophagitis, anemia in selected cases, or less commonly volvulus or obstruction in larger paraesophageal hernias
When to seek medical care
- Medical review is appropriate for persistent reflux, swallowing trouble, chest discomfort, vomiting, or abnormal imaging suggesting a large hernia
Evaluation and diagnosis
- Evaluation may include symptom review, upper GI studies, endoscopy, CT in selected cases, and treatment planning based on severity and type
Treatment approaches
- Management may include reflux treatment, lifestyle changes, weight management, and surgical referral in selected symptomatic or complicated cases
Medication classes clinicians may use
Medication often targets reflux-related symptoms rather than reversing the hernia anatomy itself.
Treatment modalities commonly paired with medication decisions
- Reflux symptom control
- Lifestyle measures
- Weight management
- Surgical review in selected cases
Acid suppression therapies
Often used when hiatal hernia contributes to reflux symptoms or esophagitis.
- omeprazole
- famotidine
FAQ
Can chest X-ray show a hiatal hernia?
Yes. A retrocardiac air-fluid level on chest X-ray can suggest a hiatal hernia.
Does every hiatal hernia need surgery?
No. Many are managed medically or observed, while surgery is reserved for selected symptomatic or complicated cases.
