What Causes Dizziness And Black Outs?

I keep having dizzy spells where my vision goes black for a second or two. I know it isn t urgent because I ve had it happen for years, but what could it be. I ve only actually lost consciousness once during something like this and that was several years ago when I was a little girl. What could be wrong?

Hello!
I read your question and understood your concern.
I think that the problems you have may be related to a low blood pressure or epilepsy.
Have you ever measured your blood pressure during these episodes?
I would recommend to measure regularly your blood pressure, have a Head up tilt test for postural hypotension, or measure your blood pressure during sitting and standing position. If there is a significant difference in your blood pressure in the two positions, it may be indicative for postural hypotension.
A chronic anemia can also cause similar symptoms, and a blood analysis would be necessary to exclude that.
If everything results normal I would recommend to do and EEG for epilepsy. It is rare, but it happens to have similar symptoms in Epilepsy.
Hope to have been of help!
Greetings!
