Reflux Cough When Eating

A persistent cough may be a symptom of chronic acid reflux, also known as gastroesophageal reflux disease, or GERD, which affects up to 20 percent of the U.S. adult population 136. Acid reflux can irritate the throat in ways that may trigger a cough when you are eating, but coughing while eating could be a sign of other conditions that warrant medical attention. If you suffer from acid reflux and find that you frequently cough when eating or swallowing, it’s important to sort out the possible reasons and factors contributing to your cough, of which GERD may be one.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

How GERD Causes Coughing

GERD is a common cause of chronic or persistent cough in all age groups. Reflux can contribute to a cough when acid irritates and inflames the esophagus, causing nearby nerves to become more sensitive and apt to trigger the cough reflex. Heartburn or regurgitation indicate that GERD may be contributing to a cough. Cough can also occur when droplets of acid reach the voice box and windpipe. Many people with LPR do not have heartburn.

Dysphagia

Reasons for Coughing After Eating

Dysphagia refers to pain and difficulty swallowing. There are many potential causes, with severe GERD among them. Abnormal narrowing of the esophagus can be a complication of GERD over the long term, and sometimes this leads to coughing or episodes of “food bolus impaction,” during which a mass of chewed food is caught in the throat without blocking the airways. This can sometimes require emergency treatment to remove the obstruction, though most episodes are resolved without medical intervention.

Aspiration

Another possible explanation for a GERD-related cough when eating is aspiration, which means that food goes down the windpipe instead of the esophagus. This happens to almost everyone at one time or another by accident, leading to the cough reflux and expulsion of the offending material. But chronic GERD can also be associated with aspiration and inflammation of the esophagus from exposure to acid gastric juices. Difficulty swallowing properly and diversion of food down the trachea can be the result.

If a chronic cough is triggered persistently by eating and is reducing your quality of life, your doctor may administer certain tests. If GERD is suspected as the reason behind a suspicious chronic cough, or a cough when eating, one or more tests may be administered. Esophageal pH testing measures acid exposure; a tube equipped with an electronic monitor is passed through the nose or mouth to the stomach to measure acid exposure over a 24-hour period. Vocal cords may be examined for water retention and enlargement of capillaries. An endoscopy -- a procedure in which a tube equipped with a light and camera is inserted to provide images of the esophagus -- may also be performed.

Let your doctor know if eating or swallowing triggers a persistent cough. According to research published in the May 2006 issue of "Journal GI Motility Online," chronic cough can have more than 20 causes, and there may be more than one cause involved in the majority of cases 6. In some cases, chronic coughing caused by acid reflux responds to a combination of lifestyle changes such as losing weight and acid-neutralizing medications called proton pump inhibitors, or PPIs, which are available both over the counter and by prescription.
