FlightPhysical.com will discuss Hypertension in sections. This parallels the FAA's instructions to AMEs concerning this common and serious problem.
Hypertension (or high blood pressure) is a common condition where the pressure of the blood flowing through the arteries of the body is higher than it should be. Pilots and controllers are often affected whether or not they have the classic "type A" personality. Much like the pressure of the air in a tire, if the pressure of the blood is too high it can damage the arteries and organs of the body. Just like the tire, if the pressure suddenly becomes very high, catastrophic events can happen. Similarly, if the pressure remains somewhat elevated for a long enough period of time, premature wear and failure can occur.
As you research hypertensin in aviators, you will want to review Measurement of Hypertension during the Pilot Exam
