Scuba diving requires a minimum level of health and fitness. Chronic health conditions, certain medications and/or recent surgery may require you to get written approval from a physician before diving.
Avoid disappointment, download and review the Diver Medical form to ensure you won’t need a physician’s approval to dive before enrolling in a scuba course. Instructors, divemasters and dive shop staff are not physicians and should not be asked for medical advice; only medical professionals can give medical clearance to dive.
If you (or your physician) have questions about medical fitness to dive, contact the experts at Divers Alert Network (DAN).
