My GI or Surgeon's never prescribe antidepressants it's always been my GP or the doctor that takes care of everything else. She is the one that sees me 4 times a year and prescribes my antidepressants and pain pills as well as my thyroid and other medications. The other doctor's don't want to prescribe those medications as they aren't around to follow up with you on them plus I don't think they keep up with what to prescribe. Please make an appointment with your GP or Internist to discuss these needs and to see if you need blood work. I wish your GI would have just told you that. I wouldn't necessarily ask for the medication that I am on. I've got other health problems and have been taking antidepressants for years. Your doctor will know what's best to prescribe. I hope you can get in soon.
