I think this is a good point; in fact, we don't know the root cause for most cases of hypertension (idiopathic). In fact, >90% of people who are normotensive at age 50 become hypertensive before they die. This is an astounding stat. We're not going to be able to fix this, IMHO, until we understand the genetic (and/or environmental) basis for HTN. Nevertheless, treatments for HTN also reduce the sequelae, such as cardiomyopathy, so these are better than just "symptomatic treatments."
