Hyperbaric oxygen therapy

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?

There's no scientific evidence that HBO therapy for multiple sclerosis works well. But, there are claims that treatment may be helpful for managing your MS bladder and fatigue symptoms.

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.

The NICE guideline for MS, which sets standards for treatment in the NHS in England, Wales and Northern Ireland, doesn't mention hyperbaric oxygen therapy for the treatment of MS. That said, some people with MS report benefits from using this type of treatment.
