For many divers across Aotearoa, being diagnosed with diabetes can feel like the end of their underwater adventures. It is a condition that requires daily management and long-term health awareness \u2014 but it does not automatically mean the end of your diving journey. With careful planning, medical oversight, a conservative approach & honest communication with their buddies, divers living with diabetes can continue to dive safely and confidently.

Over the past two decades, attitudes toward diving with diabetes have shifted with organisations such as Divers Alert Network (DAN) and Undersea and Hyperbaric Medical Society supporting research that shows that many individuals with well-managed diabetes can dive recreationally under strict protocols. It is important to obtain clearance from a doctor experienced in dive medicine, Worksafe has a list of designated diving doctors on their website<\/a>. Annual reviews are recommended, and any changes in medication, insulin regimen, or overall health should prompt re-evaluation before diving again.<\/p>\n\n\n\n

The guidelines focus on stability and control. Understanding how your body responds to insulin, food intake, stress, and physical exertion requires an adjustment period of three months to a year allowing you to establish a consistent treatment routine and learn how to recognise early signs of dropping blood glucose levels. Divers should feel confident identifying symptoms and acting quickly before they progress. Divers are advised to check their blood glucose levels multiple times before entering the water, eat appropriately timed meals, and avoid diving if readings are trending downward. Conservative dive profiles\u2014shallower depths, shorter dives and longer surface intervals\u2014add another layer of safety.<\/p>\n\n\n\n

The most immediate risk for divers with diabetes is hypoglycaemia (low blood sugar). Underwater, symptoms such as confusion, impaired judgment, shaking, seizures, or loss of consciousness can quickly become life-threatening. Diving also masks early warning signs \u2014 increased breathing or fatigue may be mistaken for exertion rather than falling glucose levels. In the longer term, poorly controlled hyperglycaemia (high blood sugar) can lead to complications affecting vision, kidney function, and the cardiovascular system. These issues may reduce your ability to respond effectively in an emergency or assist a dive buddy, which is a core responsibility in recreational diving.<\/p>\n\n\n\n

New Zealand\u2019s diving conditions make planning even more important. Many sites including the Poor Knights Islands, Marlborough Sounds & Fiordland are remote. Coastal shore dives around the country can involve currents, surge & colder waters. Cold water increases metabolic demand, potentially affecting blood sugar levels, so proper thermal protection is particularly important to reduce metabolic stress. Divers with diabetes should also factor in physical exertion (such as long surface swims), and exit points when planning their conservative dive profiles avoiding deep, technical, decompression, or overhead environment dives. Your buddy should understand your condition, know the signs of hypoglycaemia, and be aware of your emergency plan.<\/p>\n\n\n\n

Ultimately, diving with diabetes requires honesty, discipline, and a safety-first mindset. Many divers successfully return to recreational diving with the right precautions, support from their dive team, and proper planning. By choosing conservative dives, closer monitoring, and prioritising communication, living with diabetes does not have to mean giving up exploring New Zealand\u2019s remarkable underwater world \u2014 it simply means approaching each dive with greater awareness and preparation.

In short diabetic divers should do the following:
\u2022 Obtain medical clearance from a dive medicine physician.
\u2022 Maintain management of their diabetes without other organ system involvement.
\u2022 Avoid cold water, deep, or technical diving
\u2022 Use proper thermal protection.
\u2022 Always carry a source of fast-acting glucose
\u2022 Dive with an informed buddy.<\/p>\n","protected":false},"excerpt":{"rendered":"
