Worse at Night?
Acid reflux happens when stomach contents move upward into the esophagus.
The lower esophageal sphincter normally helps prevent stomach contents from flowing backward. However, when this barrier doesn’t work effectively, stomach acid can travel upward and cause the familiar burning sensation known as heartburn.
When you’re standing or sitting upright, gravity can help keep stomach contents where they belong.
When you lie down, that advantage is reduced.
That’s one reason some people notice that reflux becomes more uncomfortable after going to bed.
