Are there any medical restrictions to learning to dive?
For the basic level the only prerequisite is being physically and mentally healthy and with a certain level of fitness. Advancing to higher levels of certification will demand greater physical abilities. Before beginning a course, the student should undergo a full medical examination with a medical specialist or a physician familiar with diving. Among the different reasons that can prevent a person from diving, are epilepsy, chronic ear infections, diabetes, asthma, emphysema, heard disturbances, hemophilia, claustrophobia, depression and disturbances related to alcohol or drug use.
