Why do I get heartburn every night?
Last updated September 3, 2026.
Nightly heartburn usually means reflux: lying flat removes gravity, late meals leave the stomach full, and triggers like coffee, alcohol, chocolate, and fatty food loosen the valve that holds acid down. Heartburn two or more nights a week meets the MedlinePlus line for GERD, a chronic condition worth treating. Pymander is a free AI doctor, 24/7 by text, and can help you map your triggers.
What to do
- Close the kitchen 3 to 4 hours before bed: an emptier stomach has less to push up.
- Cut your personal triggers: coffee, tomatoes, alcohol, chocolate, fatty or spicy food.
- Raise the head of your bed and skip tight waistbands at night.
- Chest pain with breathlessness or jaw or arm pain? Emergency help now - that is a heart sign, not heartburn.
