A chronic cough can be frustrating and exhausting, especially when it lingers for weeks or months despite treatment. Many people are told their cough is caused by allergies, asthma, or postnasal drip, yet symptoms persist. What often goes overlooked is the connection between chronic cough and gastroesophageal reflux disease (GERD).
From the team at East Bay Cardiovascular & Thoracic Associates, explore the following sections for insights into the link between GERD and unexplained ongoing cough symptoms, understanding this can be an important step toward finding answers.
What Is Considered a Chronic Cough?
A cough is typically considered chronic when it lasts longer than eight weeks in adults. Unlike short-term coughs caused by colds or infections, chronic cough tends to persist even after common triggers have resolved.
Patients with chronic cough may notice that symptoms:
- Come and go without a clear pattern
- Worsen at night or after meals
- Persist despite allergy or asthma treatments
When a cough doesn’t respond to standard therapies, it may be related to foregut disorders, including reflux-related conditions.
What Is GERD?
GERD, or gastroesophageal reflux disease, occurs when stomach acid flows backward into the esophagus. This backward flow, known as reflux, can irritate the lining of the esophagus and nearby structures. While many people associate GERD with heartburn, reflux can cause a wide range of symptoms. In some cases, acid reaches higher into the throat or airway, leading to reflux-related respiratory symptoms.
How Can GERD Cause or Worsen a Chronic Cough?
GERD can trigger chronic cough in a few different ways. Acid reflux may directly irritate the throat and airway, stimulating cough reflexes. In other cases, reflux can cause subtle inflammation that makes the airway more sensitive.
This is sometimes referred to as “silent reflux,” because patients may not experience typical heartburn. Even without classic symptoms, reflux can still contribute to coughing.
This connection places GERD-related cough within a broader group of thoracic foregut disease and esophageal disorders that affect both digestion and breathing.
Can GERD-Related Cough Occur Without Heartburn?
Yes. One of the reasons GERD-related cough is frequently overlooked is that many patients never experience heartburn or chest discomfort. Instead, they may notice symptoms such as:
- A persistent dry cough
- Frequent throat clearing
- Hoarseness or voice changes
- A sensation of a lump in the throat
- Cough that worsens when lying down
Because these symptoms don’t always feel digestive in nature, GERD may not be considered right away.
Why Is GERD-Related Cough Often Misdiagnosed?
GERD-related cough is commonly misdiagnosed because chronic cough has many possible causes. Respiratory conditions are often evaluated first, and reflux may not be considered if digestive symptoms are absent. Additionally, thoracic and foregut conditions can overlap with pulmonary and ENT-related issues, making diagnosis more complex. Without a comprehensive evaluation, the underlying cause may remain untreated.
When Should You Seek Medical Evaluation?
If you’ve had a persistent cough that hasn’t improved with typical treatments, it may be time to explore less obvious causes. A thorough evaluation can help determine whether GERD or another foregut-related condition is contributing to your symptoms.
