The most common type of hypertension is termed primary or idiopathic. Secondary hypertension is associated with numerous diseases, disorders, and traumatic injuries. The National Institutes of Health define hypertension as systolic blood pressure of over 140 or diastolic pressure over 90 mm Hg. Prehypertension is defined as systolic pressure of 120 to 139 or a diastolic pressure of 80 to 89 mm Hg.1 The most common source of hypertension is from narrowing of the arterioles, which is controlled by the sympathetic nervous system and the rennin-angiotensin system of the kidneys.
