Bloating or aerophagia (swallowing air), is a rare issue that can affect some people using CPAP (Continuous Positive Airway Pressure) therapy. Here are some tips to help reduce bloating:
1. Adjust your CPAP pressure settings
Consult your provider: Excessively high pressure settings can cause air swallowing. Speak with your doctor or respiratory therapist to ensure your CPAP pressure is properly calibrated for your needs.
Use an APAP machine: APAP (Automatic Positive Airway Pressure) machines adjust pressure throughout the night, which can help reduce aerophagia.
2. Change your sleeping position
Sleeping on your back may increase the risk of air ingestion. Try sleeping on your side to reduce pressure on your stomach and throat.
3. Consider a different pillow
Use a pillow that provides better neck extension to avoid your head tilting too far downward.
4. Consider a different mask
If your mask does not fit properly, it can cause air leaks, leading to swallowed air. A nasal mask or nasal pillows may be more comfortable if you are currently using a full-face mask.
Use a mask sizing guide or book an appointment at your clinic to find the best fit.
5. Use the ramp feature
Most CPAP machines have a ramp feature that gradually increases pressure. This can help your body adjust more comfortably and reduce the risk of swallowing air at the start of therapy.
6. Practice breathing techniques
Practice exhaling against the pressure while you are awake. This can help your body better manage the airflow during sleep.
7. Try a BiPAP machine
If the issue persists, a BiPAP (Bilevel Positive Airway Pressure) machine might help. It delivers different pressures of inhalation and exhalation, which can be easier to tolerate.
8. Avoid heavy meals before bedtime
Eating heavy or gas-producing meals close to bedtime may increase your chance of bloating. Opt for lighter meals in the evening.
9. Use a chin strap
If you tend to breathe through your mouth, a chin strap can help keep your mouth closed, reducing the amount of air you swallow.
10. Watch for symptoms of GERD (Gastroesophageal Reflux Disease)
GERD can worsen bloating. If you experience symptoms of acid reflux, talk to your doctor. Treating GERD may also relieve CPAP-related bloating.
11. Consult your doctor
Persistent bloating could be a sign of another medical issue. If symptoms continue, consult your doctor or reach out to your sleep clinic.
