Are There Side Effects to Hyperbaric Oxygen Therapy?

September 09, 2019 // 1 min read Hyperbaric Oxygen Therapy

Many people may benefit from hyperbaric oxygen therapy (HBOT), particularly those with non-healing wounds, thermal burns, chronic pain, concussions, sudden hearing loss, and other conditions or disorders. But, like any medical treatment, potential side effects should be considered.

Fortunately, with HBOT, there are only a few mild and temporary side effects. These 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. If they don't go away, or if they worsen, seek medical attention as soon as possible.



At Hyperbaric Medical Solutions, safety is our highest priority. To that end, every patient at our clinics is seen and cleared by a certified hyperbaric professional to ensure all potential contraindications are addressed prior to going into a hyperbaric chamber. Additionally, all patient treatment plans are individually prepared by a hyperbaric board-certified physician, and each session is closely supervised by hyperbaric certified medical staff and trained technicians. 

To ensure your safety, we strongly urge that you receive hyperbaric oxygen therapy under strict medical supervision.
