What Researchers Did
Researchers conducted a clinical trial with 39 patients who had insulin-dependent diabetes mellitus (Type 1 diabetes) to evaluate the effectiveness of repeated hyperbaric oxygenation (HBO) courses compared to a control group of 8 patients receiving no treatment.
What They Found
The study found that repeated courses of hyperbaric oxygenation over a year were more effective than a single course in improving diabetes control, reducing insulin use, and restoring some natural insulin production. Specifically, three HBO courses given at four-month intervals showed greater benefits than two courses given six months apart. The most significant positive impact on hormone and metabolic levels was observed during the second course, with the third course helping to maintain these improvements.
Canadian Relevance
No direct Canadian connection identified. Type 1 diabetes is not a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
This study was limited by its small sample size, the absence of specific hyperbaric oxygenation treatment protocols (like pressure or duration per session), and its age, being published in 1994.
