Can hyperbaric oxygen therapy help to reduce the tolerance to glucose ( diabetes type 2 ) ?

Lowers blood glucose: In some patients, hbot (hyperbaric oxygen therapy) can increase their sensitivity to Insulin and/or increase glucose uptake and use by muscle cells. I suspect that there are other mechanisms at play, but in total, the effect is lower the amount of blood glucose. Of course this can cause problems, but generally the treatment is to eat before getting hbot, and ensure adequate nutritional reserve.

Hyperbaric oxygen: There is no evidence that hyperbaric oxygen treatment can improve tolerance to glucose. There are 13 indications for hyperbaric oxygen treatments approved for payment by medicare.

I am not aware of: any studies stating that HBOT reduces the tolerance to glucose
