<s>[INST] My 12 year old daughter has sudden and unexpected black vision and disorientation for a few seconds with no sudden standing,etc...she almost acts as if she s drunk but upon sitting it clears up-she has had complete cardiac tests done and they came back fine-could this be a blood sugar problem? She is seeing her regular physician for a complete physical within a few days and her physician has ordered blood work- [/INST] Hi,Thanks for writing to Healthcare magic.This might be syncopal attack, panic attack.
