When a person lies on the left side, the connection between the stomach and esophagus is positioned in a way that may help keep stomach acid lower.
When lying on the right side, stomach contents may be more likely to move toward the esophagus, potentially increasing the chance of acid reflux in some individuals.
This is one reason why sleep position is frequently discussed in relation to digestive comfort.
What Is Acid Reflux?
Acid reflux occurs when stomach acid flows back into the esophagus.
Common symptoms may include:
- Heartburn
- A burning sensation in the chest
- Sour taste in the mouth
- Throat irritation
- Difficulty sleeping after meals
For people who experience reflux regularly, sleep position may influence symptom severity.
