Can GERD Cause Shortness of Breath?
Medically reviewed by Lauren Okafor | MD, The Frank H Netter MD School of Medicine, Loyola University Medical Center on August 22nd, 2026.
Yes, GERD can cause shortness of breath through several mechanisms. When stomach acid backs up into the esophagus, it can trigger a reflex that causes the airways to narrow, leading to breathing difficulties. Additionally, acid reflux can reach the throat and irritate the vocal cords and upper respiratory tract. Studies show that up to 80% of people with asthma also have GERD, and acid reflux can worsen respiratory symptoms. The condition may also cause aspiration of stomach contents into the lungs, particularly when lying down. If you experience both heartburn and breathing problems, especially at night or after meals, GERD could be the underlying cause requiring medical evaluation.
