The best sleeping position for acid reflux is on your left side with your upper body raised by about 15 to 20 cm, for example on a wedge pillow for acid reflux. The left side keeps the stomach below the food pipe, and the incline lets gravity keep acid down. Raise your whole torso, not just your head.
What to get
Bed Risers for Head Elevation
Lift the head of the bed so the whole mattress slopes.

Common questions
What is the best pillow for acid reflux?
A wedge pillow that raises your whole torso by about 15 to 20 cm. Stacking regular pillows only bends the neck and does not lift the stomach.
Is left or right side better for reflux?
Left. Studies of night-time reflux show less acid exposure on the left side than the right, because the stomach sits lower than the food pipe.
Do extra pillows help heartburn?
Not much. Stacked pillows bend the neck but leave the stomach flat. A wedge or bed risers raise the whole torso.
How long after eating should I lie down?
Try to leave two to three hours between your last meal and bedtime.
When should I see a doctor?
See a doctor if heartburn happens more than twice a week, or if you have trouble swallowing, weight loss or chest pain.
