10 Hiatal Hernia Signs and Symptoms You Should Know
A hiatal hernia happens when part of the stomach pushes up through the diaphragm into the chest cavity. Many people don’t realize they have one — especially if it’s small — but symptoms can range from mild to disruptive.
Here are 10 important signs and symptoms to watch for:
1. Frequent Heartburn
A burning sensation in the chest (acid reflux) is the most common symptom. It may worsen after meals or when lying down.
2. Acid Regurgitation
You may taste sour or bitter fluid in your mouth when stomach acid flows back into the esophagus.
3. Chest Pain
Hiatal hernia–related chest pain can mimic heart problems.
⚠️ If chest pain is severe, sudden, or accompanied by shortness of breath, seek emergency care to rule out heart issues.
4. Difficulty Swallowing (Dysphagia)
Food may feel like it’s “sticking” in your throat or chest.
5. Chronic Cough
Ongoing cough — especially at night — may be triggered by acid irritating the throat and airways.
6. Hoarseness or Sore Throat
Stomach acid can inflame vocal cords, leading to persistent throat symptoms.
7. Belching or Bloating
Excessive burping, pressure, or a feeling of fullness can occur after eating.
8. Shortness of Breath
Larger hernias can press against the lungs, making breathing uncomfortable.
9. Nausea After Eating
You may feel queasy, especially after large meals.
10. Vomiting or Black Stools (Serious Sign)
Rarely, a hiatal hernia can cause bleeding.
Warning signs include:
-
Vomiting blood
-
Black or tarry stools
-
Severe abdominal or chest pain
These require urgent medical attention.
When to See a Doctor
You should talk to a healthcare provider if:

Over-the-counter reflux medications aren’t helping
-
Swallowing becomes painful
