Effects of HBO Therapy on Muscular Insulin Resistence in Type 2 Diabetes

Not Applicable

Completed

• Conditions: Non-insulin-dependent Diabetes Mellitus; Obesity
• Interventions: Procedure: Hyperbaric room air; Procedure: HBO therapy

• Registration Number: NCT01472328
• Lead Sponsor: German Diabetes Center

Brief Summary

Hyperbaric oxygen therapy (HBO) is applied for several diseases. The effect on insulin sensitivity is yet unknown. Hypothesis: HBO therapy improves insulin sensitivity in patients.

Detailed Description

HBO therapy is applied to improve wound healing in diabetic patients with foot ulcera. However, it might induce oxidative stress as well as improve antioxidative capacity. The effects on insulin sensitivity in humans and will be tested in the study.
