Causes of increase in blood pressure

I have recently been feeling a bit dizzy and when I went to the doctor she measured my blood pressure at 135/80.
My blood pressure usually comes out at 100-110/80 (last measured about 10 months ago) and she said that this change might be what's causing the dizziness.

My question is, can blood pressure change so suddenly as to bring on this dizziness? What might have caused such a change?

If it's been a gradual change over the past 10 months, then why the sudden dizziness?

I realise that BP can rise with age, and I'm a 45 yr old woman, but this seems a rather sudden increase - even if it's been over the course of nearly a year.

I'd be grateful for any ideas.

I'm a non-smoker and don't drink much, the odd glass of red wine.

Thanks for the question, you need to remember that blood pressure is dynamic in that it changes by the minute depending on the body's demand for oxygen and outside stimulus. A fluctuation from 110/80 to 135/80 is really quite normal and should not be enough of a difference to cause any symptoms.  If your BP has been steadily increasing over the past few months, it could be the result of your diet, the level of your activity, the amount of stress in your life or adding a few pounds. It could also be the result of stiffening of the arteries, so it's worth discussing with your doctor.

Did you doctor have anything to say about it? You should start with your doctor and ask about an exercise program as exercise is a great way to lower BP. Also, cut as much salt intake out of your diet and limit processed foods as they are loaded with salt. In addition, stay away from sodas as they too are a big source of salt.

I hope this helps,

Thank you for your reply.

My doctor has for the moment said that it may be age, that I watch my diet as you suggest, and asked me to come back twice weekly to be monitored. It was the regular monitoring that scared me, it made it seem like something serious.

My second check seemed much the same, the third is tomorrow. However I confess that since my pressure is usually quite low (it has been as low as 90/60 in a routine check) I made the mistake at first of assuming the dizziness was down to that and drinking isotonic drinks - could that be responsible on its own for the jump?

The dizziness may be related to something else then. I will see the nurse for a check tomorrow and friday, then will ask to see the doctor again to discuss the dizziness - so far it hasn't got any worse and hasn't let to me falling or fainting.

Thanks again for your reassurance.
