Low blood pressure?

I've taken my blood pressure for three days running. It came out first as 85 over 45! I was really shocked, and when i next took it it came out as 92 over 64. my third day (today) it was 90 over 50! I have checked this up and it is really low, apparently. I have no symptoms of hypotension apart from i often feel dizzy when i stand up. im not overweight, fit, eat healthily and do not starve myself whatsoever. i am a vegetarian however. is this it? otherwise, any suggestions?

Your pressure is low compared to norms, but low blood pressure isn't a medical problem unless it is causing problems - like dizziness.

Given the variation in your readings, its possible your blood pressure gage is not working, but you can get this range of variation if you took one reading right after awaking in the morning, and another after exercising.

There's no need to worry about it unless you think it might be causing the dizziness or other problem that you would like to correct.

Some people do tend to run low. It is possible you are dehydrated? Try drinking more fluids and if you consume caffeine or alcohol, reduce or stop this as it can pull fluids from your vessels, increasing dehydration. Some medications can do this. Are you taking anything? If increasing fluids does not help and you are not on medications, you should consult a Dr.
