I've lived with fibromyalgia for 25 years. I just started using a CPAP and here's what I've learned so far.
I want to lead with honesty: I haven't noticed dramatic changes in my fibromyalgia symptoms yet. I'm just two months in. But what I've found in my own body and in the peer-reviewed research feels too important not to share.
I'm thin. I don't fit the typical profile for sleep apnea. Nobody suggested I look into it. Yet, after looking into the research, I decided to try a CPAP anyway, partly out of curiosity, partly because after 25 years with fibromyalgia, I've struggled with sleep. know how important it is to feel better with fibro.
Turns out I was having substantially more apnea episodes than I ever knew. I couldn't feel them. Since starting the CPAP, I'm sleeping better. I can tell it is more consolidated, less fragmented. The machine data told me I went from 15-30 episodes per hour to 1. That's incredible. Whether that translates into fibromyalgia symptom improvement, I genuinely don't know yet. But I'm paying close attention.
What the science says:
A 2024 systematic review and meta-analysis published in Frontiers in Physiology found that 21% of people with obstructive sleep apnea also have fibromyalgia. The symptoms of both conditions overlap so significantly that sleep apnea is routinely missed in fibromyalgia patients.
This next statistic is the one that stopped me cold. A study out of Loyola University found that when fibromyalgia patients were properly screened in a sleep clinic setting, 85.8% had sleep apnea. In general, in outpatient clinics, where most of us are seen, the number was 3.6%. Not because the sleep apnea wasn't there, but because nobody was looking for it.
The research also confirmed something that surprised me: the association between fibromyalgia and sleep apnea is independent of body mass index. You don't have to be overweight. Being thin is not protection. I am living proof of that.
And here's something that has real implications for how fibromyalgia is currently being treated: peer-reviewed research shows that opioids and benzodiazepines commonly prescribed for fibromyalgia can actually worsen sleep apnea and increase pain. If you have both conditions and nobody has identified the sleep apnea, you may be on medications that are quietly making things worse.
Another 2024 study found that people who used their CPAP device most consistently showed the greatest reduction in fibromyalgia impact scores. It's not a cure. It's not even a guaranteed improvement. But there is something there.
What you might consider:
If you have fibromyalgia and have never been screened for sleep apnea, especially if you wake unrefreshed, have brain fog, or feel like your sleep just never restores you, ask specifically for a referral to a sleep clinic, not just a general practitioner. The screening gap is real, and the only way around it is to ask for the right evaluation.
I'll keep sharing what I notice as I continue with the CPAP. Right now, I'm two months in, sleeping better, and watching carefully.
Has anyone here been diagnosed with both? I'd really like to hear what your experience has been.
