Hyperbaric Oxygen Therapy for Multiple Sclerosis

Hyperbaric oxygen therapy (HBO) is a complementary therapy where you sit in a pressurised chamber and breathe oxygen through a mask.

The levels of oxygen in your blood and in your different body tissues go up when you start HBO.

What's the evidence for hyperbaric oxygen therapy (HBO) and MS?

Some people with MS report benefits from using this type of treatment. But there's no scientific evidence that HBO therapy for multiple sclerosis works well. There are claims that this treatment may be helpful for managing your MS bladder.

The NICE guideline for MS, which sets standards for treatment in the NHS in England, Wales and Northern Ireland, was updated in 2022. The updated guideline doesn't mention HBO therapy for treating MS in general. The only symptom it mentions is MS fatigue, where the new guideline doesn’t recommend HBO therapy to treat it.

You can find HBO treatment in most MS Therapy Centres. Usually hyperbaric oxygen doesn't cause serious side-effects.

HBO is an accepted therapy for some medical conditions such as burns, decompression sickness, serious infections, tissue injury caused by radiation and carbon monoxide poisoning.
