About 60% of people with sleep apnea also experience chronic acid reflux, or GERD (gastroesophageal reflux disease). Although the link between the two is still not clear, studies show that sleep interruptions can induce GERD. On the other hand, untreated acid reflux can impact sleep. By treating sleep apnea, it can improve GERD symptoms and by treating GERD, it can improve your quality of sleep. Without either treatment, it can have a huge impact on your quality of sleep and quality of life.
