The Untold Truth About CPAP Side Effects
“The Untold Truth About CPAP Side Effects”
Continuous Positive Airway Pressure (CPAP) therapy is a common treatment for sleep apnea, a condition where a person’s breathing repeatedly stops and starts during sleep. While CPAP is highly effective in treating sleep apnea and improving overall health, many users experience side effects that are often not discussed or addressed. In this blog post, we will dive into the untold truth about CPAP side effects and provide tips on how to manage or prevent them.
1. Dryness and Irritation of the Nose and Throat
One of the most common side effects of CPAP therapy is dryness and irritation of the nose and throat. This occurs because the constant flow of air from the CPAP machine can dry out the mucous membranes in the nose and throat. This can lead to discomfort, congestion, and even nosebleeds. To alleviate this side effect, users can try using a humidifier with their CPAP machine or using a nasal spray or gel to keep the nasal passages moisturized.
2. Skin Irritation and Pressure Sores
Wearing a CPAP mask for several hours every night can cause skin irritation and pressure sores, especially if the mask is too tight or the straps are not adjusted properly. This can lead to discomfort and even infection if left untreated. To prevent this side effect, it is important to properly fit the mask and regularly clean it. Users can also try using a mask liner or barrier cream to reduce friction and irritation.
3. Claustrophobia and Discomfort
For some users, wearing a CPAP mask can trigger feelings of claustrophobia and discomfort. This can be due to the feeling of being restricted or confined by the mask or the noise of the machine. To overcome this side effect, users can try wearing the mask for short periods of time during the day to get used to the feeling. They can also try using a mask with a different design or using a white noise machine to mask the sound of the CPAP machine.
4. Sinus Congestion
Some users may experience sinus congestion while using a CPAP machine, especially if they have allergies or a deviated septum. This can make it difficult to breathe through the nose and may require users to switch to a full-face mask or use a nasal decongestant before using the CPAP machine. Talking to a doctor about underlying causes of sinus congestion can also help alleviate this side effect.
5. Dry Mouth and Thirst

The Untold Truth About CPAP Side Effects
The pressurized air from the CPAP machine can also cause dry mouth and thirst, as it can dry out the saliva in the mouth. This can be especially problematic for users who breathe through their mouth while sleeping. To combat this side effect, users can try using a chin strap to keep their mouth closed or using a full-face mask. They can also try keeping a glass of water by their bedside to sip on throughout the night.
6. Stomach Bloating and Gas
Some users may experience stomach bloating and gas as a side effect of CPAP therapy. This can occur due to swallowing air from the CPAP machine, which can lead to gas buildup in the stomach. To prevent this, users can try adjusting the pressure settings on their machine or using a CPAP machine with a ramp feature, which gradually increases the air pressure to allow the body to adjust.
7. Skin and Eye Irritation from Mask Leakage
Mask leakage is a common issue for CPAP users, and it can cause skin and eye irritation. This occurs when the mask does not fit properly or if the user moves around a lot during sleep. To prevent this, users should make sure to adjust the mask correctly and tighten the straps as needed. Using a mask with a silicone cushion can also help reduce leakage and prevent irritation.
8. Headaches and Facial Pain
In some cases, CPAP therapy can cause headaches and facial pain. This can be due to the pressure from the mask or the straps being too tight. To alleviate this side effect, users should make sure to properly fit the mask and adjust the straps to a comfortable level. If the pain persists, it is important to consult with a doctor to rule out any other underlying causes.
9. Increased Risk of Pneumonia
There have been some studies suggesting that CPAP therapy may increase the risk of pneumonia, especially in elderly users. This is due to the constant flow of air into the lungs, which can potentially introduce bacteria and viruses. While the risk is small, it is important for users to regularly clean their CPAP equipment and consult with their doctor if they experience any respiratory symptoms.
10. Psychological and Emotional Effects
Lastly, CPAP side effects can also have psychological and emotional impacts on users. Some may feel embarrassed or self-conscious about wearing a mask while sleeping, while others may feel frustrated or overwhelmed by the adjustment process. It is important for users to seek support from their healthcare providers and loved ones to cope with these feelings and continue with their CPAP therapy for better overall health.
In conclusion, CPAP therapy is a highly effective treatment for sleep apnea, but it is not without its side effects. By being aware of these potential side effects and taking steps to manage or prevent them, users can better adjust to CPAP therapy and reap its many benefits. It is also important to consult with a doctor if any side effects persist or worsen. With proper care and attention, CPAP therapy can greatly improve the quality of life for those with sleep apnea.
