Hiatal hernias are common after 50 and most never need treating. Here are the six signs worth checking, and why Harvard Health puts the surgery rate under five percent.
Hiatal hernia symptoms are mostly reflux symptoms, and there are six worth checking. Fewer than 5% of people with one ever need surgery.
The mechanism is mechanical. Part of your stomach pushes up through the opening in your diaphragm where the esophagus passes. That loosens the muscles that normally keep stomach acid down.
Below are the six signs, the three treatment paths a provider chooses between, and the habit changes that come before any prescription.
Six signs that point at a hiatal hernia rather than your heart
Most small hiatal hernias cause nothing at all. Cleveland Clinic says that if you only have the sliding kind, which is what most people have, you probably will not feel the hernia itself.
When symptoms do show up, they come from the reflux rather than the hernia. These are the six Cleveland Clinic names.
- Heartburn. A burning sensation in your chest, especially after eating. Mayo Clinic lists it first among the symptoms a larger hiatal hernia can cause.
- Chest pain that is not your heart. Cleveland Clinic calls it noncardiac chest pain: recurring pain that feels like angina but is not. It says that for some people it may even feel like a heart attack. That is why chest pain still gets checked.
- Feeling full soon after you eat. Cleveland Clinic groups this with indigestion and a burning type of abdominal pain. Mayo Clinic lists feeling full soon after you eat as its own symptom.
- Burping and regurgitation. Food, gas and acid rising back into your throat. Mayo Clinic describes it as backward flow of swallowed food or liquids into the mouth.
- Difficulty swallowing. Cleveland Clinic describes trouble swallowing or a lump in your throat when you swallow. Harvard Health says to call your doctor about persistent difficulty swallowing.
- Sore throat and hoarseness. Cleveland Clinic attributes this to irritation from the acid reaching your throat. It is the sign people least often connect to the stomach.
Cleveland Clinic adds two warning signs for larger hernias: nausea, and shortness of breath if the hernia presses on your lungs.
Why almost nobody with one of these ever has an operation
Hiatal hernias are ordinary. Cleveland Clinic says they affect about 20% of the general population in the United States. That rises to 50% of people over 50, 60% over 60 and 70% over 70. The sliding type accounts for 95% of all of them.
Most people with hiatal hernias do not require treatment. Fewer than 5% of people require surgery (Harvard Health, 2024).
That leaves three paths, and Cleveland Clinic names all three. Wait and watch, if the hernia is not bothering you. Medication, to reduce the acid. Or surgical repair.
Medication is worth understanding honestly. Cleveland Clinic says medications cannot stop acid reflux. They reduce the acid content in your stomach. They cannot stop regurgitation, or stop your hernia growing.
Fewer than 5% of people require surgery.

The first moves are about when and how much you eat, not what. Harvard Health says to eat smaller, more frequent meals. It says to avoid eating for at least two hours before going to bed. And to sit up for at least one hour after eating.
Cleveland Clinic adds the sleeping position (Cleveland Clinic, 2023). Elevating your head at night and sleeping on your left side can help prevent reflux while you sleep.
The third lever is pressure. Cleveland Clinic names chronic coughing, straining on the toilet, obesity, frequent vomiting and heavy lifting among the forces that widen the opening.
Hiatal hernias are most common in people age 50 or older, and in people who are obese (Mayo Clinic, 2025). Constant, intense pressure on the surrounding muscles is one of the causes.
Three hiatal hernia claims that do not hold up
Three beliefs cause more worry than the condition does.
Everyone with a hiatal hernia has acid reflux. Cleveland Clinic says plainly that not everyone with a hiatal hernia has acid reflux, and not everyone with acid reflux has a hiatal hernia. The two travel together often, but not always.
It will go away on its own. Cleveland Clinic says hernias do not go away, and usually get worse over time. That does not mean yours will cause problems. It also says that if yours never causes any symptoms, you might not need to treat it.
Surgery fixes it forever. Cleveland Clinic says hiatal hernia surgery has a 90% success rate. It also says that in long term studies, up to 50% return after surgery, usually after many years. A new surgery can often fix a recurrence.
