Hyperbaric Oxygen Therapy for Inflammatory Bowel Disease (Crohn’s Disease & Ulcerative Colitis)

Inflammatory Bowel Disease (IBD), which includes Crohn’s disease and ulcerative colitis, is characterized by chronic, relapsing inflammation of the gastrointestinal tract.

Despite advances in biologics, immunosuppressants, and small-molecule therapies, many patients continue to experience:

  • Persistent symptoms

  • Medication side effects

  • Incomplete mucosal healing

  • Recurrent flares

At Saint George Hyperbarics, we offer Hyperbaric Oxygen Therapy (HBOT) as an adjunctive, physiology-based therapy designed to support tissue oxygenation, modulate inflammation, and promote mucosal healing.

Crohn’s Disease vs Ulcerative Colitis

Crohn’s Disease

  • Can affect any part of the GI tract (mouth → anus)

  • Transmural inflammation (full-thickness bowel wall involvement)

  • Fistulas, strictures, and penetrating disease may occur

  • Patchy “skip lesions”

Ulcerative Colitis

  • Limited to colon and rectum

  • Continuous mucosal inflammation

  • Primarily affects the inner lining (mucosa/submucosa)

  • Rectal bleeding is common

While distinct diseases, both share key mechanisms, such as immune dysregulation, oxidative stress, impaired mucosal healing, microvascular dysfunction, and chronic inflammatory cytokine signaling.

These overlapping pathways are where HBOT is biologically relevant.

Why Oxygen Matters in IBD

Inflamed intestinal tissue is often relatively hypoxic, meaning it is deprived of adequate oxygen due to:

  • Microvascular injury

  • Edema and swelling

  • Impaired perfusion

  • High metabolic demand from immune activation

This creates a cycle:

Inflammation → hypoxia → impaired healing → more inflammation

HBOT directly targets this physiologic bottleneck.

How Hyperbaric Oxygen Therapy May Help IBD

Hyperbaric Oxygen Therapy involves breathing 100% oxygen in a pressurized chamber, increasing dissolved oxygen in plasma and delivering oxygen to tissues with compromised blood flow.

1. Improved Mucosal Oxygenation

HBOT increases oxygen diffusion into ischemic or inflamed bowel tissue, supporting cellular metabolism even in areas of reduced perfusion.

2. Anti-Inflammatory Effects

HBOT has been shown to modulate inflammatory pathways including:

- Neutrophil adhesion and activation

- Pro-inflammatory cytokines (e.g., TNF-α, IL-1β)

- Endothelial activation and vascular inflammation

3. Enhanced Mucosal Healing

Oxygen is essential for:

- Fibroblast proliferation

- Collagen synthesis

- Angiogenesis (new blood vessel formation)

- Epithelial regeneration

4. Reduction of Oxidative Tissue Injury

While HBOT transiently increases reactive oxygen species, it also upregulates endogenous antioxidant defenses (hormetic effect), improving resilience to oxidative stress over time.

5. Immune Modulation

HBOT may help shift immune signaling away from chronic overactivation toward a more regulated healing phenotype.

What Does the Research Show?

Crohn’s Disease

Clinical studies have demonstrated that HBOT may improve outcomes in refractory Crohn’s disease, including:

  • Reduced disease activity indices

  • Improved symptom burden

  • Decreased inflammatory markers

  • Improved fistula healing in select cases

One clinical study of refractory Crohn’s disease showed significant improvement in disease activity following adjunctive HBOT.

Ulcerative Colitis

Evidence in UC suggests HBOT may be beneficial in moderate-to-severe or treatment-refractory cases.

Reported outcomes across studies include:

  • Reduced rectal bleeding

  • Improved endoscopic mucosal appearance

  • Decreased inflammatory activity

  • Improved quality of life scores

A systematic review concluded HBOT shows promise as an adjunctive therapy in ulcerative colitis, particularly in refractory disease.

Mechanistic and Translational Evidence

Broader literature supports HBOT’s role in:

  • Enhancing ischemic tissue repair

  • Modulating inflammatory bowel injury

  • Improving microvascular function in inflamed tissue

Where HBOT Fits in IBD Care

HBOT is not a replacement for standard IBD therapy.

It is best viewed as an adjunctive regenerative support therapy, potentially useful for:

  • Patients with incomplete response to biologics or immunosuppressants

  • Refractory or steroid-dependent disease

  • Poor mucosal healing despite clinical therapy

  • Post-flare recovery support

  • Complex or chronic inflammatory patterns

All patients should continue gastroenterology-directed care.

Who May Be a Candidate?

You may be a candidate for HBOT if you have:

  • Diagnosed Crohn’s disease or ulcerative colitis

  • Ongoing symptoms despite medical therapy

  • Frequent disease flares

  • Evidence of persistent inflammation

  • Desire for adjunctive, non-pharmacologic support

A full medical evaluation is required before starting therapy.

What to Expect

Treatment typically involves:

  • Comprehensive consultation with a licensed medical provider

  • Review of symptoms and medical history

  • Individualized treatment planning

  • A series of HBOT sessions over several weeks

Most patients relax comfortably in our FDA-cleared medical chambers while breathing oxygen under pressure
