If a scan or endoscopy turned up a hiatal hernia, the word "surgery" may have jumped straight to mind. For most people, it should not. Many hiatal hernias are small, cause few symptoms, and never need an operation. The question is not whether you have a hernia, but whether it is causing a problem worth fixing.
What a hiatal hernia actually is
A hiatal hernia occurs when part of the stomach pushes up through the diaphragm into the chest. This can weaken the anti-reflux barrier where the esophagus meets the stomach, which is why hiatal hernias and chronic acid reflux so often travel together. But the presence of a hernia alone is not a reason to operate.
When watchful waiting is the right call
Small hiatal hernias that cause little or no reflux are usually managed conservatively: attention to diet and habits, and medication when needed. If you have no meaningful symptoms, an incidental hernia found on imaging often needs nothing more than awareness.
When surgery is worth considering
Repair moves onto the table when the hernia is driving problems that will not settle otherwise. Common reasons to consider surgery include:
- ◆ Chronic reflux that no longer responds to PPIs, or that you do not want to medicate for life.
- ◆ A large or paraesophageal hernia, where more of the stomach has moved into the chest.
- ◆ Symptoms like difficulty swallowing, chest pressure, regurgitation, or shortness of breath after meals.
- ◆ Complications of long-standing reflux, such as Barrett's esophagus, found on endoscopy.
Larger paraesophageal hernias carry a small risk of the stomach becoming trapped or twisted, which is why they are watched more closely and repaired more readily than a small sliding hernia.
The workup comes before any decision
A responsible answer requires objective testing, not a snap judgment. That usually means an upper endoscopy (EGD), and often pH testing and manometry, to measure how much reflux you actually have and how your esophagus is working. Only then can a surgeon match the recommendation to your anatomy. When repair is warranted, it is typically done laparoscopically and often combined with a fundoplication to rebuild the anti-reflux valve.
This is general education, not a diagnosis. Whether you need surgery is determined individually after evaluation and objective testing.
The bottom line
Most hiatal hernias do not need surgery. The ones that do tend to announce themselves through reflux that will not quit, size, or specific symptoms, and the way to know for sure is a proper workup. Dr. Eduardo, a fellowship-trained foregut surgeon, starts with testing so the plan fits you, whether that plan is surgery or not.
