What Causes Lightheadedness, Dizziness And Blurred Vision?

I'm 14 and I get lightheaded and dizzy almost throughout the whole day. Sometimes upon standing up my vision is blurred, my knees give out and everything goes white for a few seconds. This started happening for quite a few months now. What does this mean?

Hello!

Welcome on Healthcaremagic!
My name is Dr. Aida and I am glad to attend you!

Your symptoms are suggestive of orthostatic hypotension. For this reason, I recommend you to measure your blood pressure in sitting and standing up position. A decrease more than 20mm Hg in your systolic blood pressure in standing up position, compared to sitting position, would be indicative of orthostatic hypotension. In such case, I would recommend performing a Head Up Tilt test and some blood lab tests (complete blood count, blood electrolytes).
Hope you will find this answer helpful!
Best wishes!
