What Causes Shortness of Breath After Eating?

If you have felt short of breath after finishing a meal, you may be wondering what causes it and whether you should be concerned. Feeling shortness of breath after eating can be distressing, but is it dangerous?

Not always. Common causes of shortness of breath after eating include acid reflux, food allergies, or inhaling food particles. Certain medical conditions such as COPD, asthma, and heart failure can also contribute to difficulties with breathing after eating.

Read on to learn about the different causes of shortness of breath after eating and when to speak with a doctor about this condition.

Causes of Shortness of Breath After Eating:

Heartburn, Acid Reflux, or Gastroesophageal Reflux Disease (GERD)

If you are experiencing heartburn, a common symptom of acid reflux, it may cause you to feel short of breath or wheezy after eating. Why does this happen? When stomach acid rises up from the stomach through the esophagus, the pipe that connects your stomach and your mouth, it can cause breathing difficulties. 

Symptoms of acid reflux include:

  • burning in the chest 
  • indigestion-like pain
  • an acidic taste in your mouth
  • burping
  • difficulty breathing
  • pain in the abdomen
  • nausea 
  • bloating
  • throat clearing
  • hoarseness

If you have acid reflux that occurs more than twice a week, you may be diagnosed with gastroesophageal reflux disease (GERD). The condition is very common; a systematic review found that the prevalence of GERD among adults in North America ranged from 18.1 to 27.8% (Sandhu & Fass, 2018).

Food Allergies and Anaphylaxis 

Being allergic to certain foods is more common than you might think. According to a recent survey, at least 10% of adults in the United States have food allergies (Gupta et al., 2019). However, you need to be aware that while some food allergies or intolerances may cause a minor reaction such as hives, food allergies can also result in anaphylaxis—a life-threatening allergic reaction.

Symptoms of anaphylaxis include: 

  • shortness of breath
  • a lump in your throat
  • tightness in your throat
  • coughing
  • difficulty swallowing 
  • nausea or vomiting
  • swelling on the skin 
  • swollen eyelids
  • a hoarse voice
  • pain in the abdomen 
  • rapid heart rate
  • dizziness or fainting
  • drop in blood pressure
  • a slow pulse 
  • cardiac arrest 

If you experience symptoms of anaphylaxis, call 911, or go immediately to the nearest emergency room. Anaphylaxis requires immediate medical attention. If you have severe allergies, you should always carry an EpiPen with you, and be ready to administer it if you recognize the symptoms of a severe allergic reaction.

Chronic Obstructive Pulmonary Disease (COPD)

COPD is a progressive form of lung disease that causes chronic shortness of breath, wheezing, frequent coughing and tightness in the chest. More than 15 million Americans suffer from COPD (American Lung Association, n.d.).

Symptoms of COPD:

  • Frequent wheezing
  • Chronic coughing 
  • Feeling short of breath while doing everyday activities
  • Being unable to breathe deeply
  • Excessive fatigue
  • Frequent respiratory infections
  • Producing a lot of mucus
  • Blue lips or fingernails

Inhaling Food

Another source of shortness of breath after eating is inhaling tiny particles of food, this is called pulmonary aspiration, which leads to pneumonia. Aspiration pneumonia occurs when you inhale either food or liquid. When this happens, it can cause an infection inside your lungs. Usually, when someone is healthy, they can cough up the food; however, this is not always the case for individuals with conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Symptoms of aspiration pneumonia:

  • wheezing 
  • chest pain
  • difficulty breathing
  • difficulty swallowing 
  • bad breath
  • fever
  • fatigue
  • a painful cough 
  • coughing up bloody phlegm

Can a Full Stomach Cause Shortness of Breath?

Yes, having a full stomach can cause shortness of breath. This is especially true for people who suffer from COPD and asthma. 

When you have COPD or asthma, having a full stomach can increase breathing difficulties. If that is the case for you, eating smaller, more frequent meals may provide relief.

How to Treat Shortness of Breath After Eating?

Determining the proper treatment for shortness of breath after eating depends on knowing the cause of it. 

Heartburn, Acid Reflux, and GERD 

Common treatments for heartburn, acid reflux, and GERD that may reduce shortness of breath after eating include: 

  • taking OTC medications such as Pepcid or Prilosec
  • eating smaller, more frequent meals
  • avoiding tight clothing 
  • not lying down within a few hours after a meal
  • quitting smoking
  • reducing intake of foods and drinks that trigger acid reflux, such as chocolate, alcohol, coffee, peppermint, citrus fruits, onions, garlic, fried foods, tomatoes, and spicy foods.

COPD and Asthma

According to the COPD foundation, there are several things asthma and COPD sufferers can do to help reduce the chances of experiencing shortness of breath from eating: 

  • eat more slowly   
  • choose foods with a lower sugar content
  • stick to softer foods that do not require as much chewing
  • restrict foods that cause bloating and abdominal discomfort (i.e. beans, raw fruits, and vegetables). 
  • avoid lying down right after eating
  • do not eat while feeling short of breath because it can trap gas, causing further difficulties with breathing 

Food Allergies

If food allergies are likely causing your shortness of breath after eating, look into the following:

  • allergy testing to determine specific food triggers
  • avoiding foods that cause allergies
  • antihistamine medications 
  • carrying an EpiPen in case of anaphylaxis 

How Do You Know if Your Shortness of Breath Is Heart-Related?

Occasionally shortness of breath can be caused by a heart condition, such as heart failure or heart attack. Shortness of breath due to heart problems arises when the heart is having difficulty filling and emptying, which causes pressure around the blood vessels surrounding your lungs (Bozkurt & Mann, 2014).

Symptoms of heart failure include:

  • difficulty breathing when lying down
  • waking up with shortness of breath
  • coughing when lying down
  • needing to prop yourself up with pillows to sleep comfortably
  • swelling of the legs or ankles
  • unusual fatigue during activities
  • weight gain

When Should I Be Concerned About Shortness of Breath?

Occasional shortness of breath is not usually a cause for concern. But if the shortness of breath that occurs after eating is causing significant distress, it’s time to seek help from a doctor.

If you experience shortness of breath and any of the following symptoms are greatly distressing, or occur for 30 minutes or longer, you should seek medical attention (American Lung Association, 2021).

These symptoms require medical attention:

  • shortness of breath with swelling in your feet or ankles
  • trouble breathing while lying down
  • shortness of breath with a high fever
  • fever or chills with a cough
  • ongoing wheezing 
  • swelling in your throat or face
  • blue tint to lips or fingers
  • pain or pressure in the chest 
  • pain down your arm 
  • confusion 

When to See a Doctor?

While occasional shortness of breath may not be a cause for concern, certain causes of shortness of breath after eating are signs of underlying disease or are a sign of a medical emergency.

And even if the problem is not an emergency, a doctor can administer various tests to determine the underlying cause of your symptoms. A doctor can then prescribe medications to help you feel better. 

Various treatments may include albuterol or steroid inhalers, antacids, proton pump inhibitors, or lifestyle and diet changes, depending on what is causing your shortness of breath after eating.
