People with type 2 diabetes, including those who use medication (eg oral glucoselowering agents, insulin), can participate in recreational scuba diving. They must be otherwise qualified to dive and meet several criteria as outlined in consensus guidelines for recreational diving with diabetes that was developed in 2005.
When evaluating persons with diabetes for medical fitness to dive, first ensure that no other exclusionary conditions (eg epilepsy, pulmonary disease) exist.
The physiological demands of diving must then be considered. People with diabetes are at higher risk than the general diving population of medical complications such as MI, angina and hypoglycaemia.
