Bloating and Gas from CPAP? You're Not Alone
You wake up. Your stomach is tight, bloated. You need to burp. Maybe worse.
This is called aerophagia, and it means you're swallowing air during the night. It's uncomfortable but fixable.
Why It Happens
CPAP pushes air into your airway. Normally, your epiglottis directs air to your lungs.
But sometimes air goes into your stomach:
- Higher pressure = more air
- Certain sleeping positions
- Anxiety and swallowing patterns
Risk Factors
You might be more prone if you:
- Need higher CPAP pressure
- Have acid reflux or GERD
- Feel anxious about CPAP
- Sleep on your stomach
- Have nasal congestion (forcing mouth breathing)
Solutions That Work
Pressure Adjustments
Talk to your provider about:
- Lowering maximum pressure (if possible)
- Increasing EPR (pressure relief during exhale)
- Trying a different mode
Don't: Adjust pressure settings yourself without guidance.
Sleep Position
Try:
- Sleeping with head elevated (use wedge pillow or elevate bed head)
- Left side sleeping (helps with digestion)
- Avoiding stomach sleeping
Timing
Before bed:
- Don't eat late (full stomach = more swallowing)
- Avoid carbonated drinks
- Limit alcohol (relaxes swallowing muscles)
Relaxation
If anxiety contributes:
- Practice calm breathing before putting on mask
- Use ramp feature (starts at low pressure)
- Try relaxation techniques
Night-to-Night Tips
If you wake up bloated:
- Get up and walk around briefly
- Gentle massage of abdomen
- Let gas pass (yes, really)
- Go back to bed
Preventing:
- Same solutions, consistently
- Track what helps in your journal
When to Get Help
Contact your provider if:
- Bloating is severe
- Happens most nights
- Home remedies aren't helping
- You're avoiding CPAP because of it
They may:
- Adjust your pressure settings
- Consider different equipment (BiPAP sometimes helps)
- Evaluate for other GI issues
What Usually Helps Most
In order of effectiveness for most people:
- Pressure relief (EPR) settings
- Sleeping position changes
- Not eating late
- Reducing pressure if possible
- BiPAP for severe cases
Good News
For most people, aerophagia:
- Improves over time
- Responds to simple fixes
- Isn't dangerous (just uncomfortable)
- Is worth solving, not quitting over
