The Diver’s Medical Checklist: Are You Fit to Dive?
Scuba diving is a fantastic activity, but it also places unique demands on our bodies due to changes in pressure. Therefore, being “fit to dive” is one of the most critical safety factors.
Before beginning your [first scuba diving course], you will be required to complete a Medical Statement. This article will help you better understand the health conditions to be aware of and why complete honesty is so important.
The Scuba Medical Questionnaire: The First Screening Step
This is a standard questionnaire developed by leading dive medical experts. It includes questions about your medical history.
- If all your answers are “NO”: Great! You are generally considered medically fit for recreational diving.
- If you have any “YES” answers: This does not mean you are banned from diving. It means you must obtain a physician’s signature clearing you for diving before you can participate in the course.
Never hide a medical condition. Doing so could pose a serious danger to yourself, your buddy, and the entire dive team.
