Yes.
Scuba diving is an exciting and demanding activity. To scuba dive safely, you must not be extremely overweight or in physically poor condition. Diving can be strenuous under certain conditions. Your respiratory and circulatory systems must be in good health. All body spaces must be normal and healthy. A person with heart trouble, a current cold or congestion, epilepsy, asthma, a severe medical problem or who is under the influence of alcohol or drugs, should not dive. If taking medication, consult your doctor before taking part in diving activities.
You will be required to complete a medical declaration prior to participating in diving activities. The purpose of this Medical Declaration is to find out if you should be examined by a physician before participating in recreational diving. A positive response to a question does not necessarily disqualify you from diving. A positive response means there is a pre-existing condition that may affect your safety while diving and you must seek the advice of a physician.
