I am 19 and female. I have never fainted in my life, or ever felt dizzy, not even fron standing for a while, but in the past week, there have been three incidences of having dizzy spells.
One was in class, I was standing but my knees weren't locked. ALl of a sudden, my teacher started spinning! And I had to grab the podium for balance. It was such an odd feeling. However, I hadn't eaten yet, but I never eat breakfast and that has not happened before.
Second, I was at work sitting down. I was on my lunch break, and already consumed food. Sitting down, the same thing happened. The person across from me started spinning.
I called my mom and she insisted I see a doctor, but I said I would wait to see if it happened again. Six days later, today actually, I was sitting in class and my teacher started spinning and I had to rest my head in my hands. However, the affects seemed longer, and although the spinning stopped within seconds like the other ones, I felt funny for about thrity mintues after that. I even ate a banana before class!
I am pretty healthy, I eat healthy and I go to the gym regularly. Im not on any medication.
