Does caffeine affect blood pressure?

Yes. Caffeine can raise blood pressure by up to 10 points in people who don't have caffeine very often. This will lower back to normal when the effects of caffeine wear off. This temporary rise in blood pressure is worse in people who already have high blood pressure. If one consumes caffeine on a regular basis, it may raise blood pressure by a small amount over the long term.
Yes. Some people are more sensitive to the blood pressure elevating effects of caffeine than others, but if you take enough caffeine in, it will elevate both blood pressure and pulse. There have been many cases now reported of the energy drinks (5 hour etc.) causing these problems, and even some sudden deaths, probably from cardiac arrhythmias in young people. If you are taking in too much, taper down.
