<s>[INST] I had something happen to me last night. I was standing in the kitchen cooking and all of a sudden I blacked out and loss hearing and loss balance. I couldn t see for about 2-3 minutes . After that hearing started coming back slowly then vision started seeing shadows after vision came back I started hyperventilating . What can be the problem? Thanks, [/INST] Thanks for elucidating your history. Possibilities as per your history are-1. Syncope-get an ECG done first though 24hrs Holder monitoring would be best to rule out cardiac cause.2. Seizure-do an EEG3. TIA (Transient ischemic attack), a kind of reversible stroke for a short duration-get a CT scan of brain, fasting blood sugar and lipid profile done. If all are normal then vasovagal attack would be the most possible explanation. Get to me back with all reports done. Thanks </s>
