Before your first scuba course, you complete a short medical questionnaire, and understanding it ahead of time removes a lot of worry. Most people tick every box "no" and are cleared to dive immediately, with no doctor's visit needed. The questionnaire simply flags conditions that deserve a professional's opinion, because diving puts unique pressures on the heart, lungs and ears. This guide explains what the form asks, which conditions matter most and when a physician's sign-off is required.
How the medical questionnaire works
The standard diver medical form is a simple yes-or-no checklist about your health history. Its only purpose is to catch conditions worth a second look.
- If you answer "no" to everything, you are generally cleared to dive.
- A single "yes" does not mean you cannot dive, only that a doctor should confirm it is safe.
- It covers heart, lung, ear, neurological and other relevant history.
- Honesty matters, because these rules exist for your own safety.
Conditions that need extra care
Certain conditions interact with the pressure changes of diving and deserve a professional assessment. Many divers with these conditions still dive safely once cleared.
- Asthma or other lung conditions, which affect how air moves under pressure.
- Heart disease or high blood pressure, given the exertion involved.
- Recent surgery, especially involving the ears, eyes or chest.
- Epilepsy, diabetes and pregnancy, which each need individual evaluation.
When you need a doctor's sign-off
If you answer "yes" to any question, most dive centers will ask for a signed medical clearance before you get in the water. This protects you and is standard practice everywhere.
It is worth handling this before you travel, since finding a dive-aware doctor on a small island can take time. Bring the completed form to your regular physician, or one experienced in dive medicine, and arrive at your course already cleared and ready to go. A little planning here saves you from losing precious holiday days searching for a signature, and it means your very first morning can be spent on the reef rather than in a waiting room.
Dive with peace of mind in Isla Fuerte
Nautilus, a PADI center on Isla Fuerte, guides you through the medical questionnaire before your course so there are no surprises, and its warm, calm reefs make for gentle, low-exertion diving. For added safety, the nearest hyperbaric chamber is in Coveñas and every diver is covered by the included Magenta insurance.
