Hi
Thanks for posting on HCM
Sorry to hear what you went through
Apart from
diabetes and heart related problems that may cause
fainting, there are many other medical conditions that may cause such.Other possible causes may include:
-A vasovagal attack or neurally-mediated
syncope, is the most common type of fainting spell.
-Ionic imbalances like low potassium, low calcium, low sodium...may cause fainting.you may have a serum electrolytes tests to exclude these causes.
-
Anemia may also cause fainting.A full blood count may help eliminate it.
-You may suffer from a simple fainting spell due to
anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs. Most people who suffer from simple fainting have no underlying heart or neurological problems and results of most tests like the ones you have done may come normal.
-You may have passed out because of the accident.In this case, just a small destraction may have been the cause.
I will suggest you just stay calm, forget about a possible cause of the accident let your Doctors take care of the present situation.
Hope this will help
Wish you a quick recovery
