Medical Fitness for Scuba Diving

For all of those that have started a PADI scuba diving course you will be familiar with Medical Fitness for Scuba Diving form. For those about to start a course it will generally be the first piece of paperwork you see.

The purpose of establishing fitness to dive is to reduce risk of a range of diving related medical conditions associated with known or suspected pre-existing conditions. This has no reference to their diving skills.

Scuba diving does involve some risk and pre-sexisting medical conditions can make the risk of a fatality while diving much higher. As a result, the regulations, requirements and medical standards relating to diving are quite strict in order to make scuba diving a safer activity.

Medical Statement

The World Recreational Scuba Training Council (WRSTC) and on a national level the Recreational Scuba Training Council (RSTC) create minimum recreational diving training standards for the various scuba diving certification agencies across the world. A part of these standards are scuba diving medical requirements.

In 2020 after the start of COVID pandemic and in conjunction with the Divers Alert Network and Undersea and Hyperbaric Medical Society new medical recommendations were made. The new medical form was more streamlined and gave the diver a bit more freedom self analyze their fitness for diving.

Over the years as scuba diving grew in popularity, more research has been conducted. We now understand more about illnesses and scuba diving and in turn more divers than ever can dive. This is in part thanks to the non-profit organization Divers Alert Network who are considered one of the world authorities on medical and safety issues in scuba diving.

Importance of being Medically Fit to Scuba Dive

Given the nature of scuba diving, depth in water and remote locations, underwater accidents can be very unforgiving. Whereas a mild asthma attack on the surface may come and pass, the same underwater would most likely end in a fatality.

Often new divers do not fully understand the dangers and implications of scuba diving. The effects that dry air, excess nitrogen and underwater pressure can have on the body. It is therefore very important that if there is any doubt that a new diver does have a medical examination prior to diving.

Having a medical condition does not automatically preclude the diver from scuba diving. Some divers will need to understand the risks prior to diving, some will have to take precautions and some unfortunately the risk will be too high.

The Divers Alert Network does an excellent job in understanding the risks of various medical illnesses however at the end of the day, if you are in any doubt, approval from a scuba diving medical expert is recommended and in some cases mandatory.

Do I Need to Know How To Swim to Scuba Dive?

This is a question that I often get asked, and really it is not as simple as YES or NO. If you want to become a certified scuba diver by doing the PADI Open Water Diver Course, the answer is yes. In the PADI Open Water Diver Course it is specified that you have to be able to swim 200 metres. This can be with any stroke. You also have to be able to tread water or float for at least 10 minutes. The reason for this is not for the fact that scuba diving requires you to swim. But rather it is for your and your groups safety. In the unlikely event that your BCD (Buoyancy Control Device) was to falter then there would be no device to kee [...]
