Most people associate acid reflux with chest tightness, heartburn, or a burning sensation in the throat. Shortness of breath and trouble breathing are common symptoms of acid reflux. 

Acid reflux (stomach acid reentering the esophagus) can be a symptom of gastroesophageal reflux disease (GERD). GERD symptoms include wheezing, coughing, and shortness of breath, also known as dyspnea. 

Continue reading to learn more about the connection between GERD and shortness of breath and how to treat this symptom when it occurs. 

GERD and Shortness of Breath Connection

Acid reflux and GERD can cause shortness of breath. Research suggests that GERD often is an underlying and sometimes unrecognized cause of asthma and other breathing troubles. When stomach acid passes through the esophagus, it can enter the lungs and throat. That irritates those areas and leads to breathing problems, including:

  • Lung inflammation: If acid is breathed into the lungs, it can cause inflammation or narrowing of the airways, leading to bronchitis or pneumonia.
  • Upper respiratory irritation: If acid irritates your upper respiratory system, including your throat, you may experience postnasal drip, chest congestion, and cough.

In addition, GERD can trigger asthma symptoms for people who have both conditions.

Other Symptoms of GERD

Symptoms of GERD include:

  • Acid reflux (burning sensation in the throat and an acidic taste)Chest pain and tightness (begins after meals and may radiate up the chest)Hoarseness (caused by throat irritation, most common in the morning)Difficulty swallowingTrouble sleepingBad breathNausea or vomiting

Complications of Untreated Acid Reflux 

If GERD is left untreated, it can cause many complications, particularly in people who experience acid reflux multiple times each week. 

Chest pain is a symptom of GERD but also of a heart attack. Seek immediate medical attention if you have chest pain but are not sure GERD is the cause. 

Respiratory Conditions

Untreated GERD or acid reflux is a cause of adult-onset asthma. It can also cause sinus infections, ulcers, and lung damage from acid being regurgitated into the lungs. These can be serious conditions, especially for people with other health concerns. 

In addition, the respiratory complications of GERD include:

  • Chest congestion
  • Cough
  • Hoarseness or laryngitis
  • Wheezing

Problems With the Esophagus

GERD takes a big toll on the esophagus, the tube that carries food from the throat to the stomach. Over time, stomach acid passing into the esophagus can cause the following:

  • Barrett’s esophagus: (changes to the esophageal lining)
  • Esophageal cancer
  • Erosive esophagitis: (difficulty or pain while swallowing)
  • Esophageal strictures: (narrowing of the esophagus)

Other Complications

Untreated GERD can lead to other complications such as:

  • Tooth decaySleep lossChronic sore throat

How to Manage Acid Reflux and Shortness of Breath 

Talking to your healthcare provider about your respiratory symptoms is important, especially if you have asthma or suspect you may have developed it. In that case, healthcare providers may provide additional asthma treatments.

Managing acid reflux can help you control and lessen your shortness of breath.

Lifestyle and Dietary Changes 

Lifestyle and dietary changes make a significant impact on people with GERD. If you have GERD or acid reflux, try these steps:

  • Avoid foods and drinks that trigger GERD (fatty, fried, and spicy foods, caffeine, and carbonated beverages). Eat smaller meals, especially in the evenings.Don’t eat within three hours of bedtime.Elevate your head for six to eight hours while sleeping, and sleep on your left side.Lose weight if advised.Quit smoking.

Medications

Over-the-counter (OTC) and prescription medications can help treat GERD and acid reflux. These include:

  • Antacids, like Tums, which neutralize stomach acid
  • H2-receptor blockers, like Pepcid Complete or Pepcid AC (famotidine), block the production of stomach acid
  • Proton pump inhibitors, like Prilosec (omeprazole), Nexium (esomeprazole), and Protonix (pantoprazole), also block stomach acid production

When to Call a Healthcare Provider 

If you notice that your GERD or breathing is suddenly worsening, you should reach out to your healthcare provider. This is especially important when you notice new symptoms or when your existing symptoms begin interfering with your ability to do your normal daily activities. 

If you’re taking Tums frequently or for more than two weeks, you should see your healthcare provider about acid reflux. 

Summary

GERD and acid reflux can both cause shortness of breath, wheezing, and other breathing problems. GERD also affects your esophagus, making it difficult to swallow. Treat your GERD to lessen breathing issues. Lifestyle changes like avoiding foods that trigger GERD, quitting smoking, and sleeping on your left side may help GERD symptoms.

A Word From Verywell 

GERD is commonly associated with a burning sensation, chest tightness, and acidic taste. But it’s also a common cause of breathing problems like coughing, wheezing, and shortness of breath. Letting your healthcare provider know about any symptoms of GERD and breathing problems you’re experiencing will get you the most effective treatment.
