Gastric acid can damage the lining of the esophagus, which can cause irritation and inflammation. This can lead to a condition called gastroesophageal reflux disease (GERD), which is a chronic and often severe form of acid reflux. GERD can cause a number of respiratory problems, including bronchospasm, laryngospasm, and aspiration pneumonia.The types of respiratory problems that can be caused by gastric acid: Acid coming up from the stomach can cause bronchospasm. This is when the airways tighten and make it difficult to breathe. Acid coming up from the stomach can also cause laryngospasm. This is when the muscles in the voice box tighten and make it difficult to speak or breathe. Gastric acid can cause respiratory problems in anyone, but some people are more at risk than others.

Older adults are more likely to have respiratory problems caused by gastric acid. Children are more likely to have respiratory problems caused by gastric acid.
