Waking up with a burning throat, a sour taste or a choking cough is frightening. In that moment, a lot of people wonder: can you die from acid reflux in your sleep?
This guide gives you the honest answer, explains why reflux gets worse at night, which symptoms need a doctor or 911, and the simple changes that help you sleep better.
Key takeaways
- Acid reflux itself is very unlikely to kill you in your sleep, but long-term reflux (GERD) can cause problems that need treatment.
- Chest pain, shortness of breath, or pain in your jaw, arm or back could be a heart attack. Call 911 right away.
- Raising the head of your bed and not eating for 2 to 3 hours before bed are two of the most useful changes.
Can you die from acid reflux in your sleep?
It’s very unlikely. Acid reflux at night can make you wake up coughing, choking or short of breath, which feels scary but usually settles within minutes. The real risks are different: long-term reflux can damage your esophagus, and chest pain at night may be your heart, not reflux. Those need a doctor.
Why reflux is worse at night
Acid reflux happens when stomach contents flow back up into your esophagus, the tube that carries food to your stomach. When it happens often, it’s called gastroesophageal reflux disease, or GERD.
The NHS says symptoms are often worse after eating, when lying down and when bending over. MedlinePlus notes that GERD symptoms may be worse at night. A 2021 review in Current Gastroenterology Reports says about half of people with GERD have reflux symptoms at night.
What can happen at night
Most night-time reflux causes heartburn, a sour taste, coughing or a hoarse voice. A few things can feel more serious, and they are usually why people ask, can you die from acid reflux in your sleep?
Waking up choking
Some people wake suddenly feeling they can’t breathe. A small 1997 study in the European Respiratory Journal described 10 people with these night-time “choking” attacks, called sleep-related laryngospasm, where the voice box briefly tightens. Breathing returned to normal within minutes, 9 of the 10 had reflux, and 6 got better with reflux treatment.
Breathing problems
The 2021 review says night-time reflux mainly affects breathing, through tiny amounts of acid reaching the airways and through airway tightening. MedlinePlus lists worsening asthma and bronchospasm (tight airways) among GERD complications. The review also found links between GERD and sleep apnea, but whether one causes the other isn’t settled.
Long-term damage
MedlinePlus says GERD can lead to ulcers or inflammation in the esophagus, a narrowing from scarring (a stricture), and Barrett esophagus, a change in the lining that can raise the risk of cancer. These build up over time, which is why frequent reflux is worth treating.
Heartburn or heart attack?
Heartburn and a heart attack can both cause chest pain, so don’t guess. The CDC lists these major heart attack symptoms:
- Chest pain or discomfort
- Feeling weak, light-headed or faint
- Pain or discomfort in the jaw, neck or back
- Pain or discomfort in one or both arms or shoulders
- Shortness of breath
The CDC adds that women are more likely to have unusual tiredness, nausea or vomiting. If you notice these, call 911 or your local emergency number right away.
How to sleep with acid reflux
If you keep asking yourself, can you die from acid reflux in your sleep, a few changes can make nights calmer. These tips for acid reflux at night come from the NHS, MedlinePlus and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
| What to do | How | Source |
|---|---|---|
| Raise the head of your bed | 6 to 8 inches (15 to 20 cm), using blocks under the bed legs or a foam wedge. The NHS says extra pillows alone can push on your belly. | NIDDK, NHS |
| Eat dinner earlier | Have dinner 2 to 3 hours before bed (the NHS says 3 to 4) and skip late snacks. | MedlinePlus, NHS |
| Eat smaller meals | Smaller, more frequent meals instead of big ones. | NHS |
| Know your triggers | Coffee, tomatoes, alcohol, chocolate and fatty or spicy foods can trigger symptoms for some people. | NHS |
| Lose weight if needed | If you are overweight, losing weight can ease symptoms. | NHS, NIDDK |
| Stop smoking | Smoking can make reflux worse. | NHS, NIDDK |

Medicines that can help
A pharmacist can suggest antacids or alginates, which the NHS says are best taken with food or soon after eating. The NIDDK says antacids, H2 blockers and proton pump inhibitors (PPIs) are all available over the counter.
Don’t use antacids every day, or for severe symptoms, without talking to a doctor first, the NIDDK advises. If you’re pregnant, take other medicines or have a long-term condition, ask a pharmacist before you start anything new.
When to see a doctor
See a doctor if lifestyle changes and pharmacy medicines aren’t helping, or you have heartburn most days, the NHS says. The NIDDK also says to see a doctor for:
- Trouble swallowing, or food getting stuck
- Vomiting often, or losing weight without trying
- Loss of appetite
- Vomit with blood in it or that looks like coffee grounds
- Black, tarry stools or blood in your stool
MedlinePlus adds choking, coughing or shortness of breath to the list. If you have chest pain or other heart attack symptoms, call 911 instead of waiting.
Frequently asked questions
Can you die from acid reflux in your sleep?
It is very unlikely. Reflux can wake you up coughing or choking, which is frightening but usually passes within minutes. The bigger worries are long-term GERD and night-time chest pain, which can be your heart; both need a doctor.
Can acid reflux stop your breathing while you sleep?
Reflux can trigger brief night-time choking attacks, when the voice box tightens for a few seconds. In a small 1997 study, breathing returned to normal within minutes. If you often wake up choking or short of breath, see a doctor to find the cause.
Can you choke on acid reflux in your sleep?
You can wake up coughing or feeling like you are choking, and MedlinePlus lists choking among GERD symptoms that need a doctor. Raising the head of your bed and not eating for 2 to 3 hours before bed can help.
How do you sleep with heartburn?
Raise the head of your bed 6 to 8 inches with blocks or a foam wedge, as the NIDDK suggests, and have dinner 2 to 3 hours before bed. Eat smaller meals and avoid foods that trigger your symptoms.
Is it heartburn or a heart attack?
You cannot always tell. The CDC lists chest pain, feeling faint, pain in the jaw, neck, back, arms or shoulders, and shortness of breath as heart attack symptoms. If you have them, call 911 right away rather than treating it as heartburn.
What is the best sleeping position for acid reflux?
Sleeping with your upper body raised helps, so the NHS suggests lifting the head of your bed by around 10 to 20 cm (4 to 8 inches). It says extra pillows alone are not a good idea because they can push on your belly.
What can be mistaken for heartburn?
Heart attack symptoms can feel like chest discomfort, and the CDC says women are more likely to have tiredness, nausea or vomiting. Ulcers and other stomach problems can also cause similar pain. See a doctor if you are unsure.
What is fundoplication?
Fundoplication is the most common surgery for GERD, according to the NIDDK. A surgeon wraps the top of the stomach around the lower end of the esophagus to help stop reflux. It is usually for people whose symptoms are not controlled by medicine.
The bottom line
Can you die from acid reflux in your sleep? It’s very unlikely, but frequent reflux (GERD) can damage your esophagus over time, and night-time chest pain may be your heart. Raise the head of your bed, eat dinner earlier and see a doctor if reflux is frequent. Call 911 for chest pain or other heart attack symptoms.
