[|Human|] I have repeated episodes of passing out & near passing out w/nausea/profuse sweating, cold clammy skin & confusion that can last for up to an hour. Sometimes I recover right away, & other times it takes quite a while. I have nausea almost daily along with getting light headed almost daily. This can happen while standing or sitting. I have it happen while driving. Luckily there was someone else with me.
[|AI|]  HelloThanks for the query to Chat Doctor. Forum. Nausea, passing out, light-headed, sweating, cold clammy skin may be due to .1 Hyper tension or hypotension. Diagnosis can be confirmed by physical examination at the time of these symptoms. Cold and clammy skin is due to sweating, while sweating may be due to dizziness and dizziness may be due to these both conditions. I mentioned in simple way, so that you can understand easily.2 Hypoglycemia or Hyperglycemia may be the another reason for such type of symptoms. Hba1 C and blood sugar level will find out the exact reason of such illness.3 Anemia and tension both causes such type of symptoms. In my opinion consult a physician and get his opinion. Good luck.
