On what basis some patients with hypertension are specifically given either diuretic or vasodilator or both to lower the blood pressure? How to confirm if the hypertension of an individual is as a result of decreased blood vessel diameter or increased blood volume?
Thanks a lot, Mohammad. It looks like there is no clear basis to claim 120/80 mmHg as normal blood pressure as well.

The choice of drugs is not a function of these things but often as a result of evidence that a class of drugs has proven effective in treating hypertension . Because majority of hypertension are essential, no immediate attempt is often made to look for particular etiology before commencing drugs. However, most of them are multifactorial and many factors contribute to it. Isolating one as the major culprit is very difficult if not impossible especially in primary hypertension.
if its ideopathic HTN, ie. renovascular, endocrine tumors or other specifically treatable causes are ruled out, then treatment should commence with ARB or CCB as first line, diuretic can then be used as second line, further add beta blockers or alfa blockers and so on according to response as needed.
it wuold be advisable to have the patient evaluated by a physician or cardiologist before embarking on this endevour.
