Q:If high blood pressure is not a disease, but a symptom, then why has lowering it become the universal focus rather than curing the cause?
A:Hypertension meets the definition of a disease. Most people suffer from primary or essential high blood pressure. The exact cause is not known, but research continues. In the meantime, treating high blood pressure makes sense because treatment can prevent a heart attack or stroke. The less common form of high blood pressure, secondary hypertension, sometimes can be cured because an exact cause can be determined.
