I am a 43 yr. old female marathon runner who runs around 40 - 75 miles a week. Ive been occasionally dizzy (maybe once a week or less) for the last two years. Ive had test for diabetes and my ears with negative results. Im going in for a tilt table test soon. Ive been monitoring my blood pressure for about two weeks (morning and evening). It averages around 103/54. Do you think my dizziness is most likely low blood pressure related? Thanks.
Yes low blood pressure can cause dizziness. Do you know your previous readings when you didn't have dizziness? what's your pulse rate. Any neck pain?is it Postural like while getting up from sleeping position? Low pulse rate is also common cause of dizziness. Reading mentioned by you is certainly low, but sometimes it is normal for some person. Maintain track of blood pressure and pulse rate.
