Hello,
Thanks for the query.
There can be various causes for your cold sweats accompanied by nausea and bloating.
The non serious causes include reflux esophagitis,alcoholic gastritis etc.
But the serious causes include  heart conditions like acute coronary syndrome which comprises of unstable angina or evolving myocardial infarction.
The symptoms include cold sweats,uneasiness,breathlessness,palpitations associated with chest pains or without chest pains.
Ideally you should go to a ER and get a cardiac evaluation done to rule out any heart involvement,to be on safer side.
The treatment for cardiac cause and non cardiac causes are entirely different.

The risks for heart involvement becomes more if a person is obese,smoker,diabetic,hypertensive,sedentary worker etc.

I hope to have answered your query however you may revert to me for any further query.
Best of luck
Thanks
