The day was fine. Then you lie down, and within an hour there’s a burning feeling in the upper stomach or behind the breastbone. Night-time stomach burning is common and miserable, and it’s usually down to a few things you can change tonight.
Here is why it gets worse when you lie down, what helps right away, and when night-time burning needs a doctor.

Why It’s Worse at Night
- Gravity stops helping. Upright, stomach acid stays down. Lying flat, it can slip past the valve at the top of the stomach (the lower esophageal sphincter).
- You swallow less. During the day, swallowing saliva constantly washes acid back down and neutralizes it. Asleep, you barely swallow.
- Late meals are still digesting. A full stomach at bedtime is still making acid and pushing on that valve.
- Evening habits add up. Alcohol, a big dinner, fatty food, chocolate, mint and late coffee all loosen the valve or raise acid.
What Helps Tonight
- Sit up or prop yourself up. Gravity is the fastest fix.
- Take an antacid for quick, short-term relief, or an H2 blocker for longer cover. Our antacids vs H2 blockers vs PPIs guide explains which works when.
- Sip water to wash acid out of the esophagus.
- Loosen tight waistbands. Pressure on your stomach pushes acid up.
What Fixes It Long-Term
1. Stop eating 3 hours before bed
This is the single most effective change. Your stomach needs time to empty before you lie down.
2. Raise the head of your bed
Lift the head end of the bed frame by about 15–20 cm (6–8 inches) using blocks or risers, or use a wedge pillow. Stacking ordinary pillows mostly bends your neck and can make things worse by folding your stomach.
3. Sleep on your left side
Because of the stomach’s shape, lying on your left side keeps the acid pool below the valve. Lying on your right side, or on your back, tends to make reflux worse.
4. Make dinner smaller and earlier
Move the big meal to lunch, and keep dinner lighter and lower in fat. Our list of foods that trigger heartburn covers the usual offenders.
5. Cut the evening drink
Alcohol relaxes the valve and irritates the stomach lining. Even one or two drinks with dinner can mean burning at 2 a.m.
If You’re Already on a PPI
Some people on a once-daily proton pump inhibitor still burn at night. Timing matters: PPIs work best taken 30–60 minutes before a meal, usually breakfast. If night symptoms continue, a doctor may change the timing or add something for night-time cover. Don’t adjust prescription doses on your own.
When It’s Not Just Acid
Night-time burning in the upper stomach can also come from gastritis, an ulcer or gallbladder problems. Our burning stomach causes guide walks through how they differ.
See a Doctor Promptly If You Have
- Chest pain, especially with sweating, breathlessness or pain spreading to the arm or jaw. Treat it as an emergency first.
- Waking up choking or coughing on acid regularly
- Trouble swallowing, or food feeling stuck
- Black or tarry stools, or vomiting blood
- Unexplained weight loss
- Burning more than twice a week despite these changes
The Bottom Line
Night-time stomach burning comes mostly from lying flat on a full stomach. Stop eating three hours before bed, raise the head of the bed rather than stacking pillows, sleep on your left side and drop the evening drink. Those four changes fix it for most people.
