Can Acid Reflux Cause Asthma?

Question: Can Acid Reflux Cause Asthma?

Answer: While research studies have shown a relationship between acid reflux and asthma, we still do not know if acid reflux actually causes asthma. This is somewhat of a double-edged sword: Acid reflux may cause asthma symptoms, but asthma medications may also worsen acid reflux symptoms.

If your asthma is poorly controlled and you are experiencing any of the following symptoms of acid reflux or asthma, you may want to consider talking with your doctor:

• Wheezing
• Chest tightness
• Shortness of breath
• Chronic cough
• Food feels as though it's getting stuck in your throat
• Hoarseness or voice changes
• Sore throat

Your doctor is most likely to look at acid reflux as a cause of your asthma or worsening asthma symptoms if your asthma:

• Started in adulthood
• Worsens after lying down or with vigorous exercise
• Is poorly controlled despite good medical treatment

How Acid Reflux May Worsen Your Asthma

Acid reflux may cause asthma or worsen asthma symptoms through a couple different mechanisms:

• Increased pulmonary resistance: When acid goes from your stomach into your esophagus, the irritation can lead to asthma symptoms as nerve stimulation in the esophagus causes bronchospasm.


• Micro aspiration: When small amounts of acid move from your stomach into your lungs, bronchoconstriction may result directly due to hyperresponsiveness.
