Hyperbaric oxygen therapy reduces inflammation and promotes remission in Crohn's disease

Studies show that between 78% and 88% of Crohn's patients who receive hyperbaric oxygen therapy experience significant improvement in symptoms and disease activity.

Understanding Crohn's disease and how hyperbaric oxygen therapy helps

Crohn's disease is a chronic inflammatory bowel disease that causes transmural inflammation in the gastrointestinal tract, most commonly affecting the terminal ileum and colon. Symptoms include abdominal pain, persistent diarrhea, weight loss, fatigue and nutritional deficiencies. The condition results from complex interactions between genetic predisposition, immune system dysfunction and environmental factors.

Complications can include intestinal strictures, fistulas, abscesses and perianal disease that significantly impact quality of life. Standard treatments include anti-inflammatory drugs, immunosuppressants, biologics and surgery, but many patients develop treatment-resistant disease. HBOT offers a complementary approach by directly reducing intestinal inflammation, promoting tissue healing and supporting remission in patients who have not responded adequately to conventional therapies.

  • Chronic abdominal pain, cramping and diarrhea

  • Weight loss, fatigue and nutritional deficiencies

  • Fistulas, strictures and perianal complications

  • Treatment-resistant inflammation requiring escalating medications

Clinical evidence for HBOT in Crohn's disease and inflammatory bowel conditions

Hyperbaric oxygen therapy has demonstrated significant benefits for Crohn's disease and inflammatory bowel conditions through multiple clinical pathways.

Inflammation reduction: HBOT reduces key markers of inflammation including C-reactive protein (CRP) and improves disease activity indices like the Crohn's Disease Activity Index (CDAI). By suppressing pro-inflammatory cytokines and down-regulating inflammatory gene expression, HBOT addresses the underlying immune-mediated inflammation that drives Crohn's disease progression.

Clinical remission: Studies demonstrate that HBOT fosters both clinical and steroid-free remission in refractory Crohn's disease. Approximately 50% of patients show radiological improvements confirmed by imaging, indicating structural healing beyond symptomatic relief. Between 78% and 88% of Crohn's patients who receive HBOT experience significant improvement in their condition.

Wound and fistula healing: For patients with severe complications including perineal pseudotumors and treatment-resistant perianal disease, HBOT supports complete healing post-surgery with no hospital readmissions during follow-up. The ability to heal complex GI wounds that resist conventional treatment makes HBOT particularly valuable for patients with complicated Crohn's disease.

Tissue oxygenation: Inflamed intestinal tissue in Crohn's disease becomes hypoxic due to vascular damage and edema. HBOT dramatically increases oxygen delivery to these tissues, supporting mucosal healing, reducing bacterial translocation and promoting the regeneration of healthy intestinal lining.

Safety profile: Clinical data consistently demonstrates that HBOT is safe and well-tolerated in IBD patients, with only mild side effects reported. This favorable safety profile makes it a viable adjunct therapy for patients who cannot tolerate aggressive immunosuppression or who have exhausted conventional treatment options.

HBOT Reduces Inflammation and Disease Activity in Crohn’s Disease: CRP and CDAI Scores Improve Significantly

Hyperbaric oxygen therapy ameliorates intestinal and systematic inflammation by modulating dysbiosis of the gut microbiota in Crohn’s disease

After 10 sessions of HBOT, CRP levels (P = 0.004) and CDAI scores (P = 0.044) significantly decreased in patients undergoing treatment, though ESR levels remained unchanged (P = 0.251). Fecal calprotectin levels improved in three patients, with normalization in one case, while hemoglobin levels showed a mild, non-significant decrease (P > 0.05). These findings suggest HBOT may reduce inflammation and disease activity in specific cases. Li Y, Sun R, Lai C, et al.

Clinical Effectiveness of Hyperbaric Oxygen Therapy in Complex Wounds

Hyperbaric Oxygen Therapy (HBOT) Shows Promising Results for Refractory Small Bowel Crohn’s Disease, with Significant Clinical Remission

In this pilot study, 14 patients with stricturing small bowel Crohn’s disease (CD) refractory to conventional treatments underwent HBOT. Over a median of 4 weeks and 11 sessions per patient (range, 3–20), 64.2% achieved clinical response, and 50–64.2% reached clinical remission at 2 and 6 months, respectively. Steroid-free remission occurred in 57% of patients, with 50% showing radiological improvement. SIBD scores improved significantly at 2 months (P = 0.03). HBOT was well-tolerated, except for one case of hemotympanum, suggesting it is a safe and potentially effective therapy for refractory CD. Kante B, Sahu P, Kedia S, et al.

Hyperbaric oxygen therapy for the management of chronic wounds: patient selection and perspectives.

HBOT as Adjunctive Therapy for Extreme Perineal Pseudotumors: Successful Healing and No Recurrence at Long-Term Follow-Up

This study evaluated the use of preoperative and postoperative hyperbaric oxygen therapy (HBOT) in four patients with extreme perineal pseudotumors (PPS) refractory to prior interventions. Patients underwent up to 30 preoperative HBOT sessions followed by abdominoperineal PPS excision and RAM flap reconstruction, with additional postoperative HBOT sessions in two cases. All patients achieved complete perineal healing within a median of 2.5 months, with no hospital readmissions for PPS at a median follow-up of 35 months. HBOT appears to be a safe and effective adjunct to surgical management for treatment-resistant PPS. Chan XH, Koh CE, Glover M, Bryson P, Travis SP, Mortensen NJ.

TESTIMONIALS

Patient experiences with HBOT for inflammatory conditions

Lisa St John, the clinic director for Bay Area Hyperbarics, had chronic refractory osteomyelitis that lasted seven years with no relief. The infection induced severe fatigue and cognitive impairment that prevented her from working and required her to sleep up to 18 hours per day. Finally, a physician recommended hyperbaric oxygen therapy with antibiotics, which after 60 osteomyelitis treatments, healed her. Shortly after being healed, she sold her home to begin her first hyperbaric oxygen therapy clinic, which she has owned for 25 years!

Lisa, 44

Jennifer had osteomyelitis of the lower jaw (mandible), which proved difficult to heal. Her teeth were becoming loose, and her doctor thought she would need surgery. However, he prescribed hyperbaric oxygen therapy before the surgery, and after 60 osteomyelitis treatments, her chronic refractory osteomyelitis healed completely, regrowing bone in her mandible. Jennifer was able to keep her teeth, and was able to return to her active lifestyle, hiking regularly with her husband.
