Most healthy people can dive without ever needing a specialist, but there are clear moments when a dive doctor is worth seeing. A dive medical is different from a normal check-up because it looks specifically at how your ears, lungs, heart and sinuses handle pressure. Knowing when to book one keeps you safe and, often, gives you peace of mind. This guide walks through the situations where a specialist visit is a smart idea, always keeping in mind that when in doubt, asking is the safe choice.
Before your very first course
Every training agency asks new divers to complete a medical questionnaire. If you answer yes to any item, such as asthma, heart conditions, recent surgery or certain medications, you are asked to get a doctor's sign-off before diving.
This is not a hurdle, it is a filter that catches issues while they are easy to manage. Most people answer no to everything and are cleared instantly, but the questionnaire exists to protect the minority who should be checked.
After illness, surgery or injury
Some events call for clearance before you return to the water. See a dive doctor if any of these apply:
- You have had recent surgery, especially on the chest, ears, eyes or abdomen
- You experienced a collapsed lung, a heart event or a stroke
- You had an ear infection or a burst eardrum
- You are recovering from a significant illness or injury
The question is always whether the affected part can handle pressure changes again, and only a proper exam can answer it.
Ongoing conditions and age
If you live with a chronic condition such as diabetes, epilepsy, heart disease or a lung problem, a dive doctor can assess whether and how you can dive safely, often with sensible precautions rather than a flat no.
Age alone does not disqualify anyone, but as the years add up a periodic check of your heart and lungs is wise. Many older divers stay active for decades by keeping an eye on their fitness to dive.
After a diving incident
If you have had any dive-related symptom, such as suspected decompression sickness, a lung overexpansion injury or an ear barotrauma, do not return to diving until a doctor has cleared you.
Diving again too soon after an incident can turn a recoverable problem into a lasting one. A specialist can tell you when your body has truly healed and what to adjust so it does not happen again.
We will help you plan around it

Important
This is general educational information, not medical advice. Always complete the medical questionnaire honestly, dive within your training and, if in doubt, consult a diving physician or contact DAN (Divers Alert Network). In an emergency in Colombia, the nearest hyperbaric chamber is in Coveñas.
