HBOT & Lyme Disease — What the Research Shows · Oceanside, CA
LYME DISEASE
DOESN'T ALWAYS RESOLVE.
For many people, Lyme disease treatment doesn't end with antibiotics. Persistent symptoms — fatigue, joint pain, brain fog, and neurological dysfunction — can continue for months or years after initial treatment. Researchers are investigating whether hyperbaric oxygen therapy can address some of the underlying mechanisms driving these chronic symptoms. This page explores what the science currently shows.
This page is educational and informational. It does not claim that HBOT treats, cures, or prevents Lyme disease or any other condition. HBOT is not an FDA-approved treatment for Lyme disease. Please work with an infectious disease specialist or Lyme-literate physician for guidance.

Understanding Persistent Lyme
WHY LYME SYMPTOMS CAN CONTINUE LONG AFTER ANTIBIOTICS END.
Lyme disease is caused by Borrelia burgdorferi, a spirochete bacterium transmitted through tick bites. When caught early, antibiotic treatment is highly effective. But a significant subset of patients — estimated between 10–20% — continue experiencing symptoms long after treatment is complete, a condition referred to as Post-Treatment Lyme Disease Syndrome (PTLDS) or chronic Lyme.
The mechanisms behind persistent Lyme symptoms remain actively debated in the medical community. Leading hypotheses include immune dysregulation triggered by the initial infection, residual inflammation in joints and neural tissue, mitochondrial dysfunction, and possible persister bacteria that survive antibiotic treatment in a dormant state.
Common Persistent Lyme Symptoms
Chronic fatigue — debilitating exhaustion unresponsive to rest
Brain fog — cognitive impairment, memory issues, difficulty concentrating
Joint and muscle pain — migratory pain affecting multiple areas
Neurological symptoms — numbness, tingling, nerve pain
Sleep disruption — poor quality sleep despite exhaustion
"HBOT may address the inflammatory and immune dysregulation that underlies persistent Lyme symptoms — creating conditions that support the body's own resolution of chronic inflammation."

Why HBOT Is Being Investigated
HBOT TARGETS INFLAMMATION AND IMMUNE DYSREGULATION — THE CORE OF CHRONIC LYME.
The rationale for HBOT in persistent Lyme comes from several converging lines of research. First, Borrelia burgdorferi is an anaerobic-preferring organism — it thrives in low-oxygen environments. High-pressure oxygen creates conditions that are inhospitable to anaerobic bacteria and may directly impair bacterial survival.
Second, and perhaps more significantly for chronic Lyme patients, HBOT addresses the inflammatory and immune dysregulation that may be sustaining symptoms even after active infection. Documented reductions in senescent immune cells and pro-inflammatory cytokines following HBOT directly target mechanisms that Lyme researchers believe drive persistent symptoms.
The Key HBOT Mechanisms Researchers Are Investigating
Anaerobic environment disruption — oxygen-rich tissue is less hospitable to Borrelia-type bacteria
Senescent cell clearance — 37% reduction in senescent immune cells reduces chronic inflammatory burden
Stem cell mobilization — 800% increase supports repair of inflammation-damaged tissue
Mitochondrial recovery — addressing energy production deficits that drive fatigue
Neural oxygenation — improving oxygen delivery to brain and nervous system for neurological symptoms

The Research Angle
WHAT HBOT DOES
THAT RESEARCHERS
ARE INVESTIGATING
THAT RESEARCHERS
ARE INVESTIGATING
HBOT delivers 100% oxygen at increased atmospheric pressure — creating conditions that researchers believe may address several of the biological mechanisms underlying persistent Lyme disease symptoms.
🦠
Anaerobic Environment Disruption
Borrelia burgdorferi is an anaerobic-preferring organism that thrives in low-oxygen tissue environments. Hyperbaric oxygen creates conditions that are directly inhospitable to anaerobic bacteria — with dissolved oxygen in plasma reaching areas of inadequate circulation where Borrelia may persist. Some researchers hypothesize that HBOT may help address bacterial persistence in low-oxygen niches that antibiotics fail to fully eliminate.
💥
Senescent Cell Clearance
Research at Tel Aviv University documented a 37% reduction in senescent immune cells following HBOT. Senescent cells are dysfunctional immune cells that accumulate in response to chronic infection and inflammation — and they sustain the chronic inflammatory environment that drives persistent Lyme symptoms. By reducing the senescent cell burden, HBOT may help interrupt the chronic inflammation cycle that keeps Lyme patients unwell long after active infection.
🔬
Stem Cell Mobilization for Tissue Repair
Research at the University of Pennsylvania documented an 800% increase in circulating stem cells following HBOT. Chronic Lyme disease involves long-term inflammatory damage to joints, neural tissue, and connective structures — damage that the body's repair systems have been unable to resolve. Mobilizing stem cells at this scale may help accelerate repair of inflamed and damaged tissue that has been sustaining symptoms for months or years.
⚡
Mitochondrial Recovery
Mitochondrial dysfunction is increasingly recognized in chronic Lyme research — the infection and subsequent inflammation disrupt cellular energy production, contributing directly to the profound fatigue that characterizes persistent Lyme. HBOT's oxygen surge supports mitochondrial function and stimulates mitochondrial biogenesis. Researchers are investigating whether restoring mitochondrial energy production can meaningfully address the fatigue and cognitive symptoms that are most disabling for chronic Lyme patients.
🧠
Neurological Oxygenation
Neurological Lyme — Lyme neuroborreliosis — affects the brain and peripheral nervous system, causing cognitive impairment, neuropathy, and neuropsychiatric symptoms. HBOT dissolves oxygen directly into plasma under pressure, improving oxygen delivery to neural tissue and reducing neuroinflammation. Researchers are investigating whether this combination can help restore function in neurological Lyme patients who have not fully recovered with antibiotic treatment alone.
🔥
Systemic Inflammation Reduction
Chronic inflammation is the common pathway through which persistent Lyme drives most of its symptoms — joint pain, fatigue, brain fog, and neurological symptoms all trace back to sustained immune activation. HBOT has documented anti-inflammatory effects including reductions in pro-inflammatory cytokines and immune cell senescence. By systematically reducing the inflammatory burden, HBOT may help the body move from a chronic inflammatory state toward resolution and recovery.
Important Context
Persistent Lyme disease is one of the most contested areas in infectious disease medicine — there is significant disagreement about its mechanisms, prevalence, and optimal treatment. HBOT for chronic Lyme is an area of ongoing investigation, not established standard of care. The research cited here addresses the underlying mechanisms (inflammation, immune dysregulation, mitochondrial dysfunction) rather than direct Lyme-specific HBOT trials. If you are dealing with persistent Lyme symptoms, please work closely with a physician experienced in tick-borne illness. HBOT may be worth exploring as a complementary approach, not a primary treatment.

800% STEM CELL INCREASE — REPAIR CELLS FOR INFLAMMATION-DAMAGED TISSUE
Dr. Stephen Thom's landmark research at the University of Pennsylvania documented an 800% increase in circulating CD34+ stem cells following a course of HBOT — and confirmed these cells migrated specifically to sites of tissue injury and inflammation. For persistent Lyme patients, this is significant: chronic Lyme involves long-term inflammatory damage to joints, neural tissue, and connective structures that standard recovery is unable to fully address.
By mobilizing the body's primary repair cells at this scale, HBOT may help accelerate recovery of chronically inflamed tissue — potentially addressing the physical pain and structural damage that sustain symptoms years after the initial infection. The stem cell migration finding is particularly relevant because it demonstrates that the mobilized cells are directed where they are needed, not randomly circulated.

37% REDUCTION IN SENESCENT IMMUNE CELLS — DIRECTLY REDUCING CHRONIC INFLAMMATORY BURDEN
The 2020 Hachmo trial at Tel Aviv University documented a 37% reduction in senescent T-cells following HBOT. Senescent immune cells are one of the primary drivers of chronic, low-grade inflammation — they no longer function normally but continue to secrete pro-inflammatory signals that sustain the inflammatory environment.
In persistent Lyme disease, this chronic inflammatory burden is a primary suspect in sustaining symptoms long after active bacterial infection. By reducing the senescent cell count, HBOT may help interrupt this inflammatory cycle — allowing the immune system to move from a sustained activation state toward resolution. The 37% reduction represents a clinically meaningful reduction in the inflammatory load that Lyme researchers believe drives PTLDS.

HIGH-PRESSURE OXYGEN CREATES CONDITIONS INHOSPITABLE TO ANAEROBIC ORGANISMS
Research published in Undersea and Hyperbaric Medicine has examined HBOT's antimicrobial properties — particularly its effects on anaerobic organisms that preferentially survive in low-oxygen tissue environments. Borrelia burgdorferi is classified as microaerophilic (tolerating low oxygen) and has been shown to have reduced viability under high-oxygen conditions.
The mechanism proposed is that HBOT's dissolved-oxygen delivery reaches tissue compartments that normal circulation inadequately supplies — the same niches where Borrelia is believed to persist. While direct clinical trials specifically targeting Borrelia with HBOT are limited, the basic science rationale is well-established, and Lyme-literate physicians have incorporated HBOT into treatment protocols based on this mechanism alongside anti-inflammatory and immune support effects.

The Broader Research Context
Persistent Lyme is a medically contested area with limited high-quality randomized trial data specifically on HBOT. The evidence base here is primarily mechanistic — HBOT demonstrably addresses inflammation, immune dysregulation, mitochondrial dysfunction, and bacterial oxygen sensitivity, all of which are implicated in persistent Lyme. Lyme-literate practitioners have used HBOT as part of integrative protocols for years, but peer-reviewed RCT data specific to PTLDS is still developing.
At Land and Sea PT, we offer HBOT as a wellness service for people navigating the difficult road of persistent Lyme symptoms. We're not an infectious disease clinic, and HBOT isn't a substitute for expert Lyme care — but for people who have tried conventional routes and are still struggling, it may be worth an honest conversation about what the evidence shows and what a protocol might look like.
