Quick answer

Which side should you sleep on with bloating, gas or acid reflux? See the positions that often help, how to raise your head safely, and what to avoid.

Plan your night

Enter the time it ended and your alarm. The planner adds the wait you choose before lying down and shows the alarm times that end a sleep cycle.

The short answer

Lying on your left side with your head and chest raised is the most commonly suggested position for reflux and a full stomach. Some small studies found less acid reaching the food pipe on the left side than on the right. Sleeping flat on your back or stomach right after a big meal is usually the least comfortable.

How to raise your head properly

  • Use a wedge pillow or raise the head of the bed by about 15 to 20 cm (6 to 8 inches) with blocks under the legs.
  • Stacking soft pillows only bends the neck and can press on the stomach, so a wedge is better.
  • Keep the raise gentle and comfortable. Your whole upper body should slope, not just your neck.

A small slope uses gravity to keep stomach contents down. It is a simple step that does not involve medicine.

Other things that help

  • Wear loose clothing.
  • Finish dinner 2 to 3 hours before bed. See how long to wait after eating.
  • Avoid alcohol, fizzy drinks, strong tea or coffee and very spicy food late.
  • Do not smoke near bedtime.
  • If you are overweight, gradual weight loss can reduce reflux for many people.

When to get medical help

Warning signs

Do not wait for sleep if you have repeated vomiting, vomit with blood or a coffee ground look, severe or worsening stomach pain, chest pain or pressure, trouble breathing, a high fever, confusion, signs of dehydration such as very dark urine, dizziness or no urination for many hours, or if you cannot keep fluids down. Pregnant women, older adults, young children and people with long term conditions should get advice sooner. This page is general education and not medical advice.

Frequently asked questions

Which side is best for acid reflux?

The left side with the head raised is most often suggested.

Is sleeping on the back bad for reflux?

Flat on the back can make reflux worse. Raising the head and chest helps.

Do extra pillows help?

A wedge works better than stacked pillows because it raises the whole upper body.

Should I sleep sitting up after a big meal?

Staying upright for a few hours after eating is a good idea. Then use a raised position in bed.

When should I see a doctor about reflux?

If it happens often, causes chest pain, trouble swallowing or weight loss, or wakes you most nights.

Should I sleep in after a late night meal or event?

A lie in of up to an hour is usually fine. Sleeping in by several hours moves your body clock later and makes the next night harder, so keep the alarm near normal and nap briefly instead.

Is 8 hours too much sleep?

Eight hours sits inside the normal range. If you regularly need 10 or more hours and still feel unrefreshed, mention it to a doctor, because it can be linked with health conditions, medicines or poor quality sleep.

How do I move my bedtime earlier?

Shift it by 15 to 30 minutes every two or three days while keeping the wake time fixed, get bright light after waking and dim lights for an hour before bed.
