I'm Dr Chaithanya attending you
This looks like typical Hypoglycemia episode, low sugar
Check your Fasting blood sugar and HBA1C in the hospital.
I also suggest you to get screened for all the blood tests like kidney, liver, heart etc, if you have not done a general check up in the recent past
If the episode doesn't repeat that is fine. if it repeats, you need to monitored and screened
Echocardiagram, Treadmill test for heart and blood tests for FBS, HBA1C, Kidney, liver are essential.
Hope this helps
