Sleep apnea and acid reflux are two common health conditions that often occur together. Many people are surprised to learn there may be a connection between interrupted breathing during sleep and uncomfortable nighttime heartburn. Understanding how these conditions are linked can help you recognize symptoms and seek appropriate treatment.
Understanding Sleep Apnea and Acid Reflux
Sleep apnea is a sleep disorder characterized by repeated pauses in breathing throughout the night. The most common type, obstructive sleep apnea (OSA), occurs when the airway becomes blocked during sleep, causing drops in oxygen levels and frequent awakenings. Acid reflux, also known as gastroesophageal reflux disease (GERD), happens when stomach acid flows back into the esophagus, leading to burning sensations, regurgitation, and irritation.
How Sleep Apnea Can Trigger Acid Reflux
Research suggests that sleep apnea can increase the likelihood of acid reflux episodes. When breathing stops during an apnea event, pressure changes occur in the chest and abdomen. These pressure shifts can pull stomach acid upward into the esophagus. At the same time, repeated awakenings may relax the lower esophageal sphincter—the muscle that normally prevents acid from traveling upward—making reflux more likely.
Additionally, sleep apnea often causes people to sleep in positions that worsen reflux, such as lying flat on their back. Reduced oxygen levels and fragmented sleep can also interfere with normal digestive processes, further contributing to nighttime reflux symptoms.
How Acid Reflux Can Worsen Sleep Apnea
The relationship works both ways. Acid reflux can irritate the throat and airway, causing inflammation and swelling. This irritation may narrow the airway and make obstructive sleep apnea symptoms worse. Reflux-related coughing, choking sensations, or a sour taste in the mouth can also disrupt sleep, creating a cycle of poor rest and worsening symptoms for both conditions.
Common Symptoms to Watch For
People who have both sleep apnea and acid reflux may experience loud snoring, choking or gasping during sleep, morning headaches, sore throat, chronic cough, hoarseness, or a persistent bitter taste. Nighttime heartburn or waking up with chest discomfort may also be signs that reflux is occurring during sleep.
Managing Both Conditions
Treating sleep apnea may help reduce acid reflux symptoms. Continuous positive airway pressure (CPAP) therapy, oral appliances, or positional therapy can improve airflow and reduce pressure changes that trigger reflux. Lifestyle changes—such as avoiding late-night meals, elevating the head while sleeping, and maintaining a healthy weight—can also help manage both conditions.
Yes, sleep apnea can contribute to acid reflux, and acid reflux can, in turn, worsen sleep apnea. If you experience symptoms of either condition, speaking with a healthcare provider or dentist trained in sleep medicine can lead to better sleep, improved digestion, and overall better health.
