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

My current glucose level is among 110 to 120 in blood after 12 hours of ayune. Hence my dad was diabetic, I want to search alternative methods to prevent the glucose level going up to 126 or plus, though I’m currently under treatment of Metformina 750 slow release for about 4 months already. Thank you [...] http://bit.ly/qcT5M4
