Do more self-checks

Lying down soon after eating makes it easier for stomach acid to travel back up, irritating the throat and triggering night cough. Meal timing, portion size and sleeping position have a measurable effect for many people.
More than 90% of the body's serotonin is produced in the gut, which is part of why digestion, mood and sleep are so tightly linked.
Evidence on diet and the microbiome is genuinely promising but still developing; results vary between people, and lifestyle steps work alongside — not instead of — medical care.

Frequently asked questions
How should I sleep with acid reflux?
Sleep on your left side with the head of the bed raised about 10-15 cm; a wedge pillow works better than stacking flat pillows. Left-side sleeping keeps the stomach below the oesophagus, so acid is less likely to travel up.
What is the best sleeping position for acid reflux?
Left side, slightly elevated, is the most reflux-friendly position. Avoid sleeping flat on your back or on your right side, which both make it easier for acid to rise.
Why is my acid reflux worse at night?
Lying down removes gravity's help, so stomach acid travels back up more easily, especially within three hours of eating. Late or large meals, alcohol and a flat position all make night-time reflux worse.
How do I stop reflux ruining my sleep?
Finish eating about three hours before bed, keep dinners lighter, raise the bed head and sleep on your left. The free self-check above can help you spot your personal triggers.
