What causes fainting spells and blurred vision?

When standing for a long period of time I start to feel sluggish, get blur vision, get really hot inside my body,and I begin to get the fainting feeling. When I get like this I check my blood pressure and also my blood sugar and there levels are normal. What could it be if it is not my diabetes or blood pressure.....

Thank you for asking on HCM!

Your symptoms seem to be caused by orthostatic hypotension.

For this reason, I would recommend you to perform a Head Up tilt test coupled with some other blood lab tests:

- complete blood count for anemia
- thyroid hormone levels for thyroid dysfunction
- blood electrolytes.

Meanwhile, I recommend avoiding prolonged standing up position and take plenty of fluids.
Hope to have been helpful!
Wishing all the best, Dr. Aida
