Inflammation is the body's natural immune response to injury, infection, or toxins, aiming to remove harmful stimuli and initiate healing. It commonly causes redness, heat, swelling, and pain, with acute cases resolving quickly and chronic cases lasting months or years, contributing to diseases like arthritis and diabetes.

​

Key Aspects of Inflammation

• Common Causes: Injuries (cuts, sprains), pathogens (bacteria, viruses), toxins, or autoimmune responses where the immune system misfires.

• Symptoms:

  • Acute: Redness, heat, swelling, and pain at the site of injury or infection.

  • Chronic: Fatigue, joint pain, digestive issues (bloating, diarrhea), and skin problems (rashes, eczema).

• Types of Inflammation:

  • Acute: Short-term, rapid response (e.g., a, sprained ankle) to clear away damage.

  • Chronic: Long-term, sometimes silent, persistent immune response that can damage healthy tissues.

• Risk Factors: Factors that increase chronic inflammation include obesity, high alcohol consumption, smoking, chronic stress, poor diet, and lack of exercise.

 

Hyperbaric Oxygen Therapy (HBOT) reduces inflammation by flooding tissues with 100% oxygen at high pressure, which downregulates pro-inflammatory cytokines, lowers oxidative stress, and boosts anti-inflammatory responses. It is clinically used to treat chronic, non-healing wounds, radiation injuries, and infections, as well as to improve oxygenation in damaged tissues.

How Hyperbaric Oxygen Therapy Reduces Inflammation

• Modulates Cytokines: HBOT suppresses pro-inflammatory cytokines (such as tumor necrosis factor-α and interleukins) that cause chronic inflammation, according to research from the Stram Center for Integrative Medicine and PubMed Central.

• Reduces Oxidative Stress: By increasing oxygen delivery, HBOT helps decrease the free radicals that contribute to inflammation-related tissue damage.

• Increases Oxygenation: HBOT forces oxygen to dissolve into blood plasma, supplying damaged, oxygen-deprived tissues (hypoxia) where inflammation typically flourishes.

• Stimulates Repair: HBOT acts as a regenerative tool, stimulating stem cell release and angiogenesis (new blood vessel growth) to promote healing, as described in studies from HBOT NC and Johns Hopkins Medicine. [1, 2, 3, 4, 5, 6, 7]

 

Key Applications

• Chronic Wounds & Diabetic Foot Ulcers: Johns Hopkins Medicine notes that HBOT is used for wounds that fail to heal due to swelling and lack of oxygen.

• Inflammatory Bowel Disease (IBD): As highlighted by Swanson Hyperbarics and clinical studies, HBOT is increasingly used as an adjunct treatment for IBD.

• Soft Tissue Injuries: It has been shown to reduce inflammation and speed up muscle repair in cases of injury.

• Radiation Tissue Damage: HBOT helps heal tissues damaged by radiation therapies, according to HBOT NC and Johns Hopkins Medicine.

 

Typical Treatment Protocols
Treatments often involve 90 to two 60-minute sessions in a chamber, frequently administered over several weeks (e.g., 5 days a week for 6 weeks). The pressure levels often range between 1.3 to 1.5 atmospheres absolute (ATA) depending on the condition being treated, notes HBOT NC and HBOT USA.
