Are There Side Effects of Hyperbaric Oxygen Therapy?


Many people may benefit from hyperbaric oxygen therapy, particularly those with non-healing wounds, thermal burns, chronic pain, arthritis and other conditions or disorders. But like any medical procedure, there could be some mild side effects.

These side effects may include:

  • Ear and/or lung barotrauma (injury caused by heightened air pressure)
  • Temporary Changes in vision
  • Lightheadedness
  • Fatigue
  • Low blood sugar

Although extremely rare, oxygen toxicity seizures and pressure injury to the lungs can occur in patients with underlying brain or lung disorders.   

Most side effects of hyperbaric oxygen therapy, however, are minor and temporary. But if they don't go away or if they worsen, seek medical attention as soon as possible.
