Since December 2016, people with well-managed insulin-dependent diabetes can now gain medical clearance to learn to SCUBA dive in Australia. Diving is a popular and exciting sport and the Australian diabetes community will be quick to embrace it; as such, healthcare professionals need to be informed about the risks and approaches to safely diving with diabetes. People who are cleared to participate must tightly control the variables that impact blood glucose levels, including activity, timing, food and insulin. This talk is a personal account of the speaker’s (a PADI dive professional and a type 1 diabetic) experience diving with type 1 diabetes and details how she puts the UHMS/DAN recommendations into practice on dive days. Key elements of the self-assessment process, long- and rapid-acting insulin adjustments, meal timing, responses to blood glucose trends, handling hypoglycaemia and approaching multi-dive days will be discussed, along with some considerations for people using insulin pumps.
