feeling dizzy and blurry vision after running

[Icyblue]

My 13 yr old dd was running 200 m at school sport day this morning. When finished 5 minute later she started to feel dizzy and her vision gone slightly yellow and blurry. Her teacher gave her a biscuit and water and she recovered soon after. Is this something to worry about?

I think she needs to get checked out by the GP. Could be nothing, could be something as simple as low blood sugar, but dizziness and blurred vision after exertion warrants a trip I reckon.

definitely a visit to GP. Hope all goes well x
