Re: low systolic high diastolic pressure
130/80 sounds fine to me! Before certain "financial interests" created the 120/80 "ideal" which sent people in search of another expensive drug, 140/90 was only considered "high normal" and was some healthy people's natural pressure all their long lives.
But losing weight never hurts! Your pressure will likely lower some more with a little less weight. Remember to eat healthy (organic if possible) foods and never starve yourself just to get to that "ideal" sub-120/80.
