Acid Reflux and Persistent Cough: What You Need to Know
Persistent coughing can be exhausting — especially when it lingers for weeks and doesn’t respond to cold meds or allergy treatments. If you’ve tried everything and still can’t stop coughing, acid reflux may be the silent cause.
For many people, acid reflux shows up without heartburn. Instead, it manifests as a stubborn, dry cough that worsens after meals, at night, or when lying down. Understanding how acid reflux and chronic cough are connected is the first step toward real relief — and preventing more serious complications down the line.
The Surprising Link Between Acid Reflux and Persistent Cough
Most of us think of reflux as burning pain in the chest. But reflux can also rise high into the throat, irritating the larynx and even the airways. This condition, sometimes referred to as laryngopharyngeal reflux (LPR), is a common trigger for unexplained coughs.
Why reflux causes coughing:
- Direct irritation: Acid reaches the throat, triggering a cough reflex.
- Nerve sensitivity: Even acid in the lower esophagus can stimulate nerves that cause coughing.
- Silent symptoms: Many don’t feel heartburn — only the cough.
This kind of reflux-induced cough is often misdiagnosed as postnasal drip or asthma. If you’ve tried those treatments with no luck, it’s worth considering reflux as the underlying issue.
How to Know if Your Cough Might Be Reflux-Related
Since reflux-related cough can mimic other issues, it helps to look for patterns. Consider when your cough shows up, what foods trigger it, and whether it’s worse at certain times of day.
Common signs of reflux-induced coughing:
- Cough that lasts longer than 8 weeks
- Throat clearing or hoarseness, especially in the morning
- Symptoms worsen after eating or at night
- Cough doesn’t improve with allergy or cold medicine
- Sensation of postnasal drip without mucus
These signs aren’t diagnostic on their own, but they’re strong clues. You can also try keeping a food-and-symptom diary for a week — it’s a helpful tool when speaking with a provider.
First-Line Relief Strategies to Reduce Coughing
If you suspect acid reflux is behind your lingering cough, there are several low-risk changes you can try before turning to medication. I was skeptical at first, but once I started applying a few of these consistently, my cough finally began to calm down.
Simple changes that often help:
- Don’t eat late at night: Finish your last meal at least 3 hours before bedtime.
- Elevate your upper body: Sleeping flat can make reflux worse — try a wedge pillow or raise the bed head. See our bed elevation tips.
- Avoid triggers like chocolate, alcohol, and fried foods: They relax the esophageal sphincter and worsen reflux.
- Chew gum after meals: It stimulates saliva, which helps neutralize acid. Learn more in this gum guide.
Many people with reflux-related cough see improvement within a few weeks of consistent lifestyle changes — but consistency is key.
When to Consider Medical Evaluation
If your symptoms don’t improve with lifestyle adjustments, it’s time to involve a healthcare provider. Long-term reflux can cause damage to the esophagus or even lead to conditions like Barrett’s esophagus if left untreated.
Diagnostic options may include:
- 24-hour pH monitoring: Measures acid levels in your esophagus over a full day.
- Endoscopy: Visual check for inflammation, damage, or structural issues.
- Empirical treatment: A short trial of reflux medication to see if symptoms improve.
In many cases, proton pump inhibitors (PPIs) or H2 blockers are prescribed to reduce acid production and give tissues a chance to heal. Always use medications under medical supervision, especially if your cough is persistent or disruptive.
