The article details why most people fear procedures, i.e. colonoscopy, endoscopy and other invasive diagnostic tests. As the author, I believe that fear is a significant barrier that can influence outsomes. If a patient is fearful and and has a "bad" experience with the procedure, then the patient will not likely return any time soon for following-up testing. I outline the signs and symptoms of fear so that medical professionals can identify those people who are at risk, and intervene to prevent a "bad" outcome for the patient.
