Most adults have experienced heartburn before and can agree that it’s not a pleasant sensation. Those who have been dealing with the side effects of acid reflux might find themselves wondering: can heartburn cause shortness of breath?
In this article, we will explore the causes, symptoms, and treatment options associated with acid reflux, and answer your commonly asked questions on the subject.
What is “Heartburn”?
The word “heartburn” refers to one of the symptoms of acid reflux. Heartburn describes a burning sensation and general chest pain experienced during an episode of acid reflux. Acid reflux occurs when the esophageal sphincter, the muscle that seals the opening of your esophagus, fails to close properly, allowing stomach acid to make its way up into the esophagus.
Frequent episodes of acid reflux may indicate the presence of acid reflux disease, otherwise known as Gastroesophageal Reflux Disease (GERD). GERD is one of the most prevalent gastrointestinal conditions in the United States, affecting an estimated 20% of the adult population. Unlike occasional heartburn, which can be triggered by a single meal or stressful event, GERD is a chronic condition that can cause daily discomfort and, if left unmanaged, lead to long-term damage to the esophagus and respiratory system.
Common Causes of Acid Reflux
Situations that put unnecessary pressure on the stomach can help contribute to flare-ups of acid reflux, this includes circumstances like pregnancy, hernias, or wearing tight-fitting clothing. Acid reflux can also be a side effect of some medications, including certain blood pressure drugs, aspirin, anti-inflammatory medications, and some antidepressants.
Most commonly, heartburn and other GERD symptoms are caused by the things we eat. Acidic, fatty, and spicy foods can all cause the production of excess stomach acid, leading to acid reflux. Eating too much, too fast creates excessive amounts of stomach acid. Eating too late can also be problematic, since heartburn often occurs when someone is lying down to sleep, as gravity is no longer helping to keep stomach contents in place.
Other contributing lifestyle factors include smoking, obesity, alcohol consumption, and high levels of stress, all of which can either weaken the esophageal sphincter or increase acid production in the stomach.
Common SymptomsGERD or Acid Reflux
Common symptoms of GERD or acid reflux include:
Burning sensations in chest and upper abdomen
Sour taste in mouth
Regurgitation and vomiting
Difficulty swallowing
Chronic cough
Bad breath
Sore throat
Inflamed windpipe and breathing problems
It is worth noting that not everyone with GERD experiences the classic burning chest sensation. Some individuals, particularly those with a condition called Silent Reflux (laryngopharyngeal reflux), experience primarily throat irritation, chronic coughing, or hoarseness without the hallmark burning feeling. This can make GERD harder to identify and is one reason it often goes undiagnosed or misattributed to other conditions.
What Is GERD and Asthma?
Now to answer the question at hand: can heartburn cause shortness of breath? In short, yes, acid reflux causes shortness of breath. How does this work? Typically, these breathing difficulties occur at night when stomach acid has a higher potential to rise up the throat and enter the lungs. This causes the respiratory airways to swell and become inflamed, which then leads to shortness of breath, chronic coughing, and wheezing.
This mechanism, in which aspirated stomach acid irritates and inflames the airway tissues, is why GERD is now recognized as a significant trigger for respiratory symptoms. In severe cases, stomach acid reaching the lungs can contribute to aspiration pneumonia, a condition requiring immediate medical treatment.
It is also important to note that people with asthma often experience issues with GERD. While the exact connection between the two conditions is not fully understood, it is known that the breathing issues associated with asthma are often accompanied by symptoms of acid reflux, and vice versa. Some researchers believe the relationship is bidirectional, acid reflux can trigger asthmatic episodes, and the physical effort of coughing or wheezing during an asthma attack can increase abdominal pressure and worsen reflux.
Heartburn vs. Heart Attack: Knowing the Difference
Because GERD and acid reflux can cause chest pain and shortness of breath, they are frequently mistaken for cardiac events, and this confusion is clinically significant. Knowing when chest pain warrants an ER visit is essential for anyone who experiences these overlapping symptoms.
The key distinctions to watch for are these: heartburn-related chest discomfort typically presents as a burning sensation that worsens after meals or when lying down, often accompanied by a sour taste in the mouth or regurgitation. It usually improves when you sit up or take an antacid. Cardiac chest pain, on the other hand, tends to feel more like pressure, tightness, or squeezing, and it may radiate to the arm, jaw, neck, or back. It is often accompanied by sweating, nausea, dizziness, or sudden shortness of breath that is unrelated to meals.
If your chest pain has not resolved after 15 minutes, is accompanied by shortness of breath and cold sweats, or if you have any doubt about the cause, call 911 or go to the emergency room immediately. It is always safer to rule out a cardiac event. If abdominal discomfort accompanies your symptoms, understanding when abdominal pain warrants a trip to the ER can also help you make that call with confidence.
Prevention and Treatmentfor Heartburn
There are many things you can do to prevent the occurrence of acid reflux and to manage the symptoms of GERD. First and foremost, focus on maintaining a diet that is free of fatty, spicy, and acidic food to prevent your system from producing extra stomach acid. Additionally, maintaining a healthy weight, quitting smoking, and limiting stress can also help you manage the symptoms of acid reflux.
It is also recommended that patients avoid putting any unnecessary pressure on the stomach, this means avoiding overly tight clothing, or clothing that constricts the midsection.
Eating smaller, more frequent meals rather than large portions reduces the volume of stomach contents at any given time, which helps limit the likelihood of reflux. Avoiding carbonated beverages, caffeine, chocolate, and mint, all of which can relax the esophageal sphincter, is also beneficial. Lastly, avoiding food within two to three hours before bed and elevating the head of the bed during sleep reduces the risk of nighttime heartburn and other symptoms.To treat heartburn that is already ongoing, contact your doctor for Proton Pump Inhibitors and H2 Receptor Blockers, you can also purchase over-the-counter antacids for heartburn relief.
These medications work by reducing the amount of acid the stomach produces, giving the esophageal lining a chance to recover. For patients with more severe or persistent GERD, a physician may recommend additional diagnostic tests and a more comprehensive management plan.
When to Get Help
While occasional heartburn can be annoying, it does not pose any long-term risks. However, a chronic condition like GERD can lead to further health complications when left untreated.
Prolonged exposure to excessive amounts of stomach acid can put the esophagus at risk of inflammation, scarring, ulcers, and even cancer. Conditions like Barrett’s Esophagus and Silent Reflux can also occur, along with tooth decay, ongoing breathing issues, and an overall decreased quality of life.
For these reasons, if you feel you are struggling with GERD or another chronic acid reflux condition, seeking out medical advice for assistance would be an important step in taking care of your health. You should seek prompt evaluation if your heartburn is occurring more than twice per week, if over-the-counter medications are providing little relief, if you are experiencing difficulty swallowing, unexplained weight loss, or if your breathing symptoms are worsening.
