Migraine headaches with CPAP

Will cpap treatment bring on a migraine headache? It seems my migraines come more often when using cpap.


It shouldn't exist migraine headaches with CPAP. Most patients with sleep apnea have fewer migraines when they start using CPAP treatment.
However, if you have now a different pressure settings on your CPAP machine, then it must be a reason for your headaches.

Regarding sleep apnea, the main reason for migraines is the oxygen deprivation of your brain (hypoxemia). The CPAP machine should deliver enough oxygen to make you feel better. Other causes may be:

  • hypercapnia

  • increased intracranial pressure

  • sleep disturbance caused by depression

  • change in cerebral blood flow

You can learn more about sleep apnea headaches here.

Regarding your CPAP treamtent, maybe you have a leak or a differet pressure setting.

Have you thought to see again a sleep technician? He can detect the differences.

I get migranes now and than, but when I started using my Cpap I had one for 5 days-this has never happened before. I stopped taking pills after the 5th pill gave no results. I stopped the cpap and am fine. Afriend suggested that the pressure setting was to high causing to much pressure on the sinus cavity (which is another reason for some migranes) I cant figure out how to change the pressure and a trip to the clinic is way to far down the road!!

I've suffered migraines for years... like 30+ years. I've had problematic periods with my migraines that were more frequent than usual, and periods when they were less problematic. Since using the CPAP, my migraines have become worse... as in I wake with a headache that is worse than usual (I'm a chronic migraine patient living with headaches every day). And the headache doesn't go away or lessen as the day progresses.

I'm on a very low level of pressure for my settings and I use a warm humidifier to alleviate the sinus cavity concerns. It's done nothing to improve my migraine problems which have now become aggravated by the CPAP. To just assume that the pressure is too high and the likes is very naive and a very narrow scope of understanding. Migraine is a very complicated disease that encompasses more than just headaches. Headaches are merely one symptom of the disease - and just happen to be the one symptom that EVERYONE associates with the term "migraine".

Please refrain from giving advice if you are not fully educated on the subject. You could end up putting out a lot of bad information that could result in a lot of damage to those of us who suffer these issues.

The cause of migraines is still unknown. How do you get off stating that migraines are the result of oxygen deprivation??? Before you start spouting off about what "fixes" migraines, you should learn to do some research. You should also keep in mind that what may work for some may not for others. Migraine is an extremely complex DISEASE that can be aggravated by any number of things. There is clear documentation that while CPAP treatment can help with OSA, it can also cause increased headaches in some migraine patients. You should also keep in mind that headaches are NOT migraines... And migraines are NOT headaches. Migraine patients may suffer headaches, as they are one of the most common symptoms of migraine. However, they are not in and of themselves "migraines". Many migraine patients do not even experience headaches. Get your medical facts straight before you try to advise others on what you think you know!
