Hyperbaric Oxygen Therapy for Fibromyalgia: What a 2023 Meta-Analysis Found

Fibromyalgia is one of the more difficult conditions to treat, partly because it doesn’t show up cleanly on a scan or a blood test. Chronic widespread pain, fatigue, tender points and brain fog can be very real and very disruptive, even when standard diagnostics look unremarkable.

That combination has led researchers to explore a range of interventions, including hyperbaric oxygen therapy (HBOT). The results are genuinely interesting — and genuinely mixed, which is exactly why they deserve an honest look rather than a marketing pitch.

At Core iV Therapy®, we’d rather walk you through what the research actually found than oversell what our 1.3 ATA mild hyperbaric chamber can do for fibromyalgia symptoms.

What the Research Found

A 2023 meta-analysis pooled four randomized controlled trials involving 163 participants with fibromyalgia. It found improvements in fibromyalgia-impact measures and tender-point counts among people who received HBOT.

But here’s the part that’s easy to skip if you only read the headline: pain improvement itself was not statistically significant across the pooled trials, and side effects were reported more frequently in the HBOT groups than in controls.

In three words: promising, interesting, not magic.

Why This Matters for How We Talk About It

Fibromyalgia is a condition where people have often already tried multiple treatments with disappointing results. That makes honest expectation-setting especially important. We won’t tell someone HBOT will resolve their pain — the pooled data doesn’t support that specific claim.

What we can say is that the broader impact measures and tender-point findings are worth taking seriously as an area of ongoing investigation, and that hyperbaric oxygen may be a reasonable therapy to explore as part of a broader, individualized approach — not a stand-alone fix.

How We Approach Sessions

Our mild hyperbaric chamber operates at approximately 1.3 ATA — a pressure chosen for tolerability, which matters given that the research noted more frequent side effects with HBOT than with sham treatment. Sessions include supplemental oxygen delivery by mask when appropriate, and we build protocols around repeated, individualized sessions rather than a single visit, consistent with how the supportive studies were structured.

What This Looks Like at Core iV

For clients with fibromyalgia exploring HBOT, we typically emphasize:

• A conservative, individualized approach given the higher reported side-effect rate
• Sessions of roughly 60 minutes at therapeutic pressure
• Supplemental oxygen delivery by mask
• Realistic framing — supportive for impact measures, not a proven pain cure
