There are a few medical requirements for scuba diving, but nothing too serious. You need to have a basic level of fitness, and be comfortable in the water. You also need to have a clean bill of health, and be free from any conditions that might affect your diving.
The most important medical requirement for scuba diving is a dive medical. This is a simple medical examination that will check your fitness to dive, and make sure you are free from any conditions that could affect your safety underwater.
Many dive shops and resorts will require you to have a dive medical before you can go diving with them.
If you have any questions about the medical requirements for scuba diving, please consult your doctor or a qualified dive professional.
