RE-THINKING DISEASE:   Hypertension

Conventional Medical Thinking:  Hypertension is idiopathic (cause unknown), identified when a person’s measured blood pressure is higher than desirable (using criteria from the American College of Cardiology).  Hypertension is seen as a “risk factor” for other heart disease and other vascular diseases.

Systems Biology Thinking:  Hypertension is one phase of inflammatory vascular disease, resulting from inflammatory infiltration of lining of arteries, resulting in stiffening and narrowing.  Systems Biology research points to hyperarousal of the deep brain as an instigating factor.

Trauma-Health Equity-Neurobiology Lens – Severity of Hypertension correlates with severity of adverse experiences, especially experience of Everyday Discrimination.  In the USA, black men are particularly at risk. Research has shown that transition from normal blood pressure to hypertension in black boys can start at age 8.
