Hyperbaric Oxygen Treatment for Endometriosis
Can hyperbaric oxygen help in endometriosis? Mechanisms, evidence, and when HBOT may fit as adjunct care.

Hyperbaric Oxygen Therapy and Endometriosis: A Reframed Overview
Hyperbaric oxygen therapy (HBOT) is being investigated as a biologically targeted adjunct for endometriosis based on its ability to directly modify tissue oxygen tension—an upstream driver of inflammatory signaling, angiogenesis, and lesion persistence. Rather than acting on hormones or pain pathways alone, HBOT addresses the hypoxic microenvironment that enables endometriotic tissue to survive and propagate, positioning oxygen modulation as a distinct and mechanistically novel therapeutic avenue.
Understanding Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy entails breathing 100% oxygen in a pressurized chamber at levels above atmospheric pressure. In this environment, oxygen dissolves more effectively into the bloodstream and tissues, leading to a significant rise in tissue oxygenation. HBOT has long-standing applications in wound healing, radiation injury, decompression sickness, and chronic infections.
Oxygen and Endometriosis Biology
Endometriosis lesions frequently inhabit hypoxic, or low-oxygen, microenvironments that drive inflammation, angiogenesis, fibrosis, and pain signaling. Within endometriotic tissue, hypoxia-inducible factors (HIFs) are upregulated and support lesion survival and progression. By elevating tissue oxygen levels, HBOT may help counteract these hypoxia-driven pathways.
How HBOT Might Influence Disease Processes
Research indicates several potential benefits of HBOT in the context of endometriosis. It may reduce both local and systemic inflammation, downregulate hypoxia-inducible factors, inhibit angiogenesis within lesions, improve mitochondrial function alongside cellular repair, and enhance immune modulation. In animal models, exposure to hyperbaric oxygen has been shown to decrease the size and activity of endometriotic implants and to lower inflammatory cytokine levels.

Early clinical observations and limited studies suggest that HBOT may alleviate pelvic pain and improve symptoms in individuals with endometriosis. Some reports describe diminished lesion vascularity and reductions in inflammatory markers following treatment. Despite these encouraging signals, large-scale randomized controlled trials in humans remain limited, and HBOT is not regarded as a standalone therapy.
Integrating HBOT Into a Treatment Plan
- HBOT functions best as a complementary therapy rather than a substitute for excision surgery or medical management.
- It may be considered for select patients within an integrative plan, particularly when persistent inflammation, impaired healing, or complex pain syndromes are present.
- Treatment protocols vary, but they typically comprise multiple sessions delivered over several weeks.
- Administration should occur in accredited medical facilities under physician supervision.
Safety Profile and Treatment Screening
- Potential risks include ear or sinus barotrauma.
- Temporary vision changes can occur.
- Oxygen toxicity is a concern with prolonged exposure.
- Claustrophobia may affect tolerance.
- Patients should undergo careful screening before starting treatment.
Key Points
Hyperbaric oxygen therapy offers a promising adjunctive option for targeting hypoxia-driven inflammation and tissue dysfunction in endometriosis. While preliminary findings are encouraging, additional clinical research is needed to refine protocols, identify ideal candidates, and clarify long-term outcomes. When thoughtfully integrated into care, HBOT may aid healing and symptom relief for select patients.

Quick Answers
Can endometriosis cause inflammation-related weight gain?
Yes—there can be a connection, but it’s usually not as simple as “inflammation makes you gain fat.” Endometriosis is an inflammatory condition, and that inflammation can drive fluid shifts, pelvic and abdominal swelling, bowel slowing/constipation, and the classic waxing-and-waning “endo belly,” all of which can look and feel like weight gain even when body fat hasn’t changed. Pain, fatigue, and stress can also reduce activity or change appetite patterns, which can indirectly affect body composition over time.
What’s also emerging in research is a possible link between endometriosis and certain metabolic risk patterns in some people (like central waist changes and lipid markers). That doesn’t prove endometriosis directly causes metabolic changes—or that metabolic changes cause endometriosis—but it does support why some patients feel their body is harder to “regulate” while the disease is active. If weight changes, bloating, or a new shift in your waistline is part of your story, our team can help you sort out what’s most likely inflammation and GI distension versus longer-term metabolic or hormonal contributors, and build a plan that aligns with your symptoms and goals. If you’d like, you can reach out to schedule a consultation so we can evaluate the full picture and discuss treatment options, including excision and coordinated whole-person care.
What are alternatives to ibuprofen for endometriosis pain?
If ibuprofen isn’t working for you—or you can’t take it—there are still several evidence-based ways we can approach endometriosis pain, depending on what’s driving it. Some pain is more inflammatory and cramp-like, while other pain behaves more like nerve pain (burning, electric, radiating) or becomes amplified over time through central sensitization. That’s why the “best” alternative isn’t one universal medication, but a plan matched to your pain pattern and goals (including fertility).
On the medication side, alternatives may include other NSAIDs, acetaminophen, and—when symptoms fit—neuropathic pain modulators (commonly medications used for nerve pain) that help calm overactive pain signaling. Some patients also ask about low-dose naltrexone; it’s a promising option for certain centralized pain conditions, but it isn’t proven as an endometriosis-specific treatment, so we treat it as an adjunct with careful expectations. Non-medication options can be genuinely useful too, especially when layered together—things like home electrical stimulation (TENS) for flares, and pain-focused psychological strategies that reduce the pain–stress amplification loop.
Most importantly, alternatives to ibuprofen are about managing symptoms while we keep sight of the underlying disease: symptom control alone can feel like a band-aid if active lesions are still driving inflammation, scarring, and organ irritation. Our team can help you sort out what type(s) of pain you’re experiencing and build a multimodal plan that fits your body and your timeline—whether you’re pursuing definitive diagnosis, considering excision surgery, or trying to stabilize day-to-day function in the meantime. If you’d like, reach out to schedule a consultation so we can personalize options rather than relying on trial-and-error.
What if I can’t take NSAIDs for endometriosis pain?
When you can’t take NSAIDs, it often exposes an important truth about endometriosis care: anti‑inflammatories may blunt symptoms, but they don’t treat the disease itself. Without NSAIDs, some people notice that flares feel more intense or last longer—especially if pain has become “wired in” over time through nervous system sensitization (meaning the body learns to amplify pain signals). That doesn’t mean you’re out of options; it means we need a more structured plan than a single medication.
In our practice, we typically think in layers: addressing pain drivers (inflammatory, hormonal, nerve-related, and musculoskeletal) while also evaluating whether endometriosis or adenomyosis itself needs definitive treatment. Non‑medication tools can play a bigger role here—especially pelvic floor therapy for muscle guarding and pelvic nerve irritation, and nervous-system-focused strategies that reduce pain amplification over time. If symptoms are escalating or you’re relying on workarounds because NSAIDs aren’t safe for you, that’s often the point when it’s worth stepping back and building a comprehensive plan with our team, including discussion of excision surgery when indicated and coordinated support to improve day-to-day function.
Can endometriosis cause a pulling or tugging sensation?
Yes—endometriosis can cause a pulling, tugging, or “stuck” sensation in the pelvis or lower abdomen. This often comes from inflammation and fibrosis (scar-like tissue) that can tether organs to each other or to the pelvic sidewall, so movements like standing upright, stretching, twisting, bowel movements, or sex may feel like something is being pulled.
That pulling sensation can also show up alongside other endometriosis patterns—pain that worsens around your period or ovulation, deep pain with intercourse, bowel or bladder pain, or a feeling of pressure and heaviness. Because endometriosis can involve many structures (including bowel, bladder, ureters, and deeper pelvic tissues), the exact “tug” you feel can hint at where disease may be affecting anatomy and nerves.
If you’re noticing this symptom, we encourage you to track when it happens (cycle timing, specific movements, bowel/bladder activity) and what else comes with it—those details help us map likely sources and plan a targeted evaluation. When appropriate, minimally invasive excision surgery can both confirm the diagnosis (with biopsy) and remove tethering disease to relieve symptoms—reach out to schedule a consultation with our team to talk through your history and options.
Can endometriosis qualify as a disability?
Yes—endometriosis can qualify as a disability in some situations, but it isn’t “automatically” considered one in every case. When symptoms like pelvic pain, fatigue, bowel/bladder pain, or pain with sex significantly limit day-to-day functioning, a person may be protected under the Americans with Disabilities Act (ADA) and may be eligible for workplace accommodations.
For Social Security disability benefits, endometriosis is not a listed condition, so approval typically depends on showing how your symptoms and functional limitations prevent you from sustaining work. Documentation matters: clear diagnosis details, treatment history (including surgery and symptom management), and records describing how often symptoms flare and what activities they limit. If you’re navigating work or disability questions, our team can help evaluate the medical side of your case, clarify the disease versus pain mechanisms (including central sensitization), and create a plan that supports both symptom control and long-term treatment goals—reach out to schedule a consultation.
