Scuba diving places unique physical demands on the body. Most healthy people can dive safely, but certain medical conditions require evaluation or may prevent diving. Here is a guide to common medical questions.
The PADI Medical Statement questionnaire is required for all divers. If you answer "yes" to any condition on the form, you need a physician's clearance before diving. This is for your safety.
Asthma: mild, well-controlled asthma may be compatible with diving. Active asthma or exercise-induced asthma typically requires specialist evaluation. The risk is air trapping during ascent, which can cause lung over-expansion.
Diabetes: type 1 and type 2 diabetes with insulin can be compatible with diving under specific protocols (stable blood sugar, no recent hypoglycemic episodes, physician clearance). DAN has specific guidelines.
Heart conditions: any history of heart problems requires cardiology clearance. The physical exertion of diving, cold water, and changes in blood flow during immersion place demands on the cardiovascular system.
Ear problems: chronic ear infections, perforated eardrums, or difficulty equalizing pressure may prevent diving. Equalization problems are the most common medical issue we see.
Pregnancy: diving is NOT recommended during pregnancy due to unknown risks to the fetus from pressure changes and bubble formation.
Medications: many medications are compatible with diving, but sedatives, strong antihistamines, and certain psychiatric medications may not be. Consult a dive medicine physician.
In Bali: BIMC Hospital and Kasih Ibu Hospital have doctors familiar with dive medicine. We recommend getting clearance before your trip, but it can be arranged locally if needed.
