How long it takes to develop aneurysm of aorta in 23 y/o? if i have very high bp whenever active for 6 months. how high is dangerous for 6 month time?

Over 50 yrs.: in 23 yr old aneurysm is not the danger but Brain hemorrhage is if BP is persistently high. Also it is not high BP as dangerous as is the high swings as may happen with anxiety and exercise or isometric excesses like wt. lifting. So you should have maximum safe reserve in BP control of 30 mm. u may have aneurysm if u have Marfans Syndrome, coarctation of Aorta or other elastic tissue disease.
