Can GERD Cause Chest Tightness and Shortness of Breath?

Gastroesophageal reflux disease (GERD) occurs when stomach or duodenal contents flow back into the esophagus, leading to irritation and a range of uncomfortable symptoms. While heartburn and acid regurgitation are the most well-known signs, some individuals may experience atypical symptoms such as chest tightness or difficulty breathing.

When acidic stomach contents travel up into the esophagus and potentially reach the respiratory tract, they can irritate the airways and trigger coughing, wheezing, or a sensation of breathlessness. This is especially common in people who suffer from nighttime reflux, as lying flat reduces the effect of gravity, making it easier for acid to rise.

If someone experiences unexplained shortness of breath or chest discomfort, they often first visit a pulmonologist or general physician. However, if conventional treatments for respiratory issues fail to provide relief, it's important to consider GERD as a possible underlying cause, particularly if symptoms worsen after meals or during sleep.

To confirm whether acid reflux is contributing to these symptoms, doctors may recommend 24-hour pH monitoring, which checks for the presence of acid in the throat or esophagus over an extended period. This test helps identify abnormal reflux patterns and guides more targeted treatment strategies.

In summary, while chest tightness and breathing difficulties are not the most common GERD symptoms, they can occur—especially in cases of laryngopharyngeal reflux or nighttime reflux. Recognizing this connection is key to receiving proper diagnosis and effective care.
