What Researchers Did
Researchers conducted a preliminary crossover study to determine if well-controlled type 1 diabetic scuba divers could maintain stable blood glucose levels during a simulated dive to 375 kPa (approximately 27 meters of seawater).
What They Found
The study found no statistically significant differences in serum glucose levels for the eight type 1 diabetic divers during the simulated dive compared to a control exercise on the surface. All diabetic divers remained free of hypoglycemia symptoms and signs throughout the trial, with no subject having a serum glucose level below 4 mmol/liter before the end of the study.
What This Means for Canadian Patients
This research suggests that Canadian patients with well-controlled type 1 diabetes and no long-term complications might safely participate in scuba diving, challenging previous advice from some diving agencies. Patients should consult with their healthcare providers to discuss these findings and assess their individual suitability for diving.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study's small sample size means its findings may not apply to the broader diabetic diving population, including individuals with type 2 diabetes.
