Lyme disease, a tick-borne illness caused by the Borrelia burgdorferi bacterium, affects thousands each year, often with debilitating long-term symptoms. While antibiotics remain the primary treatment, many patients with persistent or chronic Lyme symptoms seek alternative therapies. One increasingly researched and utilized option is Hyperbaric Oxygen Therapy (HBOT)—a form of oxygen therapy administered in pressurized chambers.
In this comprehensive guide, we explore the science behind HBOT for Lyme disease, its benefits and limitations, and real case studies to help you evaluate whether this emerging treatment might be right for you.

HBOT involves breathing 100% pure oxygen in a pressurized environment, typically inside a chamber that increases atmospheric pressure to 1.5 to 3 times higher than normal. This process helps increase oxygen delivery to tissues, promote healing, and combat infections.
According to Johns Hopkins Medicine, HBOT is already FDA-approved for 14 medical conditions, though Lyme disease is not officially one of them. Yet, promising anecdotal and early clinical evidence suggests benefits for chronic Lyme patients.
Borrelia burgdorferi is a microaerophilic organism, meaning it thrives in low-oxygen environments. HBOT floods the body with oxygen, potentially creating an inhospitable environment for the bacteria. This oxygen-rich atmosphere may weaken or kill off the spirochetes responsible for chronic symptoms.
Chronic Lyme often causes inflammation, neurological issues, and tissue damage. Research suggests HBOT:
These effects are crucial for patients with neurological Lyme disease (neuroborreliosis) and joint or soft-tissue damage.
A study published in the Journal of Spinal Cord Medicine showed HBOT's positive influence on neuroinflammation, which aligns with symptoms experienced by Lyme patients.
Many Lyme patients suffer from brain fog, memory issues, or neuropathy. HBOT helps increase cerebral oxygenation, which may enhance cognitive performance and reduce neural inflammation.
HBOT can make antibiotics more effective by increasing drug delivery to affected tissues and improving oxygen-dependent bacterial killing.
Oxygen-rich environments may help reduce fatigue, muscle pain, and post-treatment inflammation, improving patients' daily functioning and quality of life.
HBOT may support the detoxification process by improving liver function and lymphatic drainage—critical for managing Herxheimer reactions during Lyme treatment.
While generally safe, HBOT isn’t risk-free. Possible side effects include:
It’s important to consult a medical professional before starting therapy. People with conditions like untreated pneumothorax, certain types of lung disease, or seizure disorders should avoid HBOT.
A 32-year-old woman with neurological Lyme experienced minimal improvement from antibiotics. After undergoing 40 HBOT sessions at 2.0 ATA, she reported significant improvement in cognition, reduced joint pain, and increased energy. MRI follow-ups showed decreased brain inflammation.
A male patient diagnosed with Lyme and Babesia co-infection underwent a combined protocol of IV antibiotics and 30 HBOT sessions. Notable improvements included reduced headaches, better sleep, and cessation of night sweats.
These stories reflect individual results and are not replacements for clinical evidence, but they provide insights into HBOT’s practical impact.
Dr. Richard Horowitz, a prominent Lyme-literate physician, has included HBOT in some of his multi-modal treatment plans. While clinical trials are limited, he notes that "for some chronic patients, especially those with neurological involvement, HBOT has provided meaningful symptom relief."
Likewise, clinics specializing in integrative Lyme treatment, such as The Hyperbaric Medical Center, offer HBOT as part of personalized protocols.
Most insurance companies do not cover HBOT for Lyme disease since it’s not an FDA-approved indication. However, some patients have had success getting partial reimbursements with documentation of chronic, treatment-resistant symptoms.
Out-of-pocket costs can range from $100 to $300 per session, with full treatment plans typically requiring 20 to 40 sessions.
When considering HBOT, keep the following in mind:
Monitor for Herxheimer reactions and work with a Lyme-literate doctor for support.

While not a silver bullet, HBOT offers a promising adjunctive approach for managing Lyme disease—especially for those with lingering neurological or systemic symptoms. Backed by early research and positive anecdotal evidence, oxygen therapy may accelerate healing, reduce inflammation, and support immune recovery.
Before beginning treatment, consult your healthcare provider, ensure safe access to a certified facility, and explore all your therapeutic options.
