Summary

This study tests whether breathing a special mix of low and high oxygen air (called intermittent hypoxic-hyperoxic training) can help lower blood sugar in people with type 2 diabetes. About 250 adults aged 50-74 will be split into groups receiving either a 3-day or 10-day course of this therapy, or a placebo. The main goal is to see if it reduces fasting glucose and HbA1c levels one month after treatment.
