Ive been having weird faints and blackouts. i need answers! please help.?

sweetie, you may only be 17, but you have grown-up medical issues and because of your surgery, you always will have them. you have already identified the probable causes: not taking your vitamins, smoking and drinking. so, take some time to do the right thing...take your meds, don't smoke, don't drink...and see if that alleviates your fainting spells. if not, then go directly to your mother and get her to take you to your byp doctor and see if something more serious may be wrong. don't wait too long. tc.
