Life expectancy for young hypertensives 20-30?

If hypertension occurs at a young age, then various causes for such hypertension should be sought by the physician. For example, kidney disease and benign tumors of the adrenal gland along with certain kinds of vascular disease should be ruled out.
If these relatively rare causes of hypertension can be ruled out, then treatment to a normal blood pressure should be instituted and maintained. I don't know of any life expectancy data specific to the question, but believe that if the blood pressure is kept at normal levels that the life expectancy would be essentially normal. Untreated hypertension of years duration would probably be associated with significant bodily insults (for example, stroke).

Thanks much Dr.Miller, I have checked for all these causes "except aldosteronism" which my doctor says is uneccesary since my thyroid levels were normal. Would that be accurate?

Im not sure about the adrenal tumors, although ive had 2 abdominal CT scans, 2 echocardiograms, 2 Ekg's and several blood tests. All seems normal, I guess I have genetics to blame, eh?

Thank you very much for your response, Doctor.
