How does heartburn affect your ears?
Heartburn is an uncomfortable burning sensation just behind your breastbone. It’s caused by digestive acid moving into your esophagus, which is the tube between your throat and your stomach. Heartburn is typically experienced:
- After eating
- In the evening
- After lying down
If you have frequent heartburn that interferes with your lifestyle, you may have gastrointestinal reflux disease (GERD). Two extraesophageal variants of GERD are laryngopharyngeal reflux (LPR), also known as silent reflux, and nasopharyngeal reflux (NPR). These vary in sensation within your esophagus and other areas of the throat.
Here’s a breakdown:
- GERD: backflow of stomach acid that irritates your esophagus
- LPR: backflow of stomach acid that irritates your larynx (voice box) and pharynx (part of your throat above the esophagus and larynx, behind the mouth and nasal cavity)
- NPR: backflow of stomach acid that irritates your nasopharynx (upper part of the your throat behind your nose)
For some people, LPR and NPR can lead to ear pressure and ear pain, often in the form of eustachian tube obstruction (ETO).
Each of your ears has a eustachian tube. This is a canal connecting your middle ear to your nasopharynx to equalize the pressure in your middle ear to the air pressure outside your body.
Studies have suggested a connection between ETO and the variants of GERD. According to a 2015 study, LPR and ETO appear together in many cases. A 2014 study found that nasopharyngeal reflux may have a role in the development of ETO.
Eustachian tube obstruction symptoms
Your eustachian tube connects your middle ear and throat. ETO, also referred to as blocked eustachian tubes or eustachian tube dysfunction, is characterized by symptoms such as:
- Ear pain
- A feeling of fullness in your ears
- Hearing difficulties
- Ringing or popping noises in your ears
- Dizziness
LPR symptoms
Most LPR symptoms appear in your throat, such as:
- Feeling like there’s a lump in your throat or needing to clear your throat
- Sore throat
- Difficulty swallowing
- Hoarseness
- Persistent cough
- Postnasal drip
- Irritated larynx
While the majority of people with GERD experience heartburn, according to Stanford Medicine, only about 35% of those with LPR experience this symptom.
