[|Human|] afternoon my 15 yr old son is always having dizzy spells almost always when he stands up or moves to quickly, and seems to have low blood pressure lots of the time, he has had a massive growth spurt over the last 6months and has reached 6ft 1 so not sure whether the growth could be part of the reason
[|AI|]  Hi, Welcome to Chat Doctor forum, Normally dizziness can happen if anyone stands in hot sunlight for a long duration in the afternoon, that is called syncope. But if without any trigger or heat or strain, he gets dizzy, then he needs to be investigated thoroughly which includes blood tests, cardiac check with an ECG and also EEG if needed. Kindly consult a pediatrician without further delay. Hope I answered you query adequately. Let me know if there is any further clarification you need. Take Care.
