Medical conditions which disqualify you from diving

Some medical conditions make diving dangerous and can cause injury or worse. Before you begin with scuba diving a medical questionnaire can be given to you. If you’ve answered yes to any of those questions it’s likely that a medical review of a doctor is required.

I made a list of medical problems which can disqualify you from scuba diving:

Excessive alcohol or drugs use.
Scientists don’t know much about the effects of diving while having a fetus, so it’s dissuaded to dive while pregnant.
Central nervous system disorders.
Lung problems like asthma. If you’ve asthma you can get an attack underwater.
Diabetics who are insulin dependent. They can pass out while scuba diving if their blood sugar is too low.
Ears and sinuses aren’t clear and healthy.
You don’t feel comfortable underwater.

I recommend you to obtain a physical examination of a doctor who is familiar with scuba diving. Health is too important to neglect so you can be a scuba diver.
