Great Vent so let's brain storm and others can add to this
1. You posted, " The doctor does know for a fact I have severe acid reflux, hiatal hernia, my lower esophageal sphincter doesn't close and is wide open, esophagus has been eroded, etc etc."
I am wondering why he keeps on tossing meds at you if he has all this info so why not do the Ph study and then move to surgery ? Just me thinking out loud.
2. IBS - well most people that have severe IBS issues will see a GI specialist to rule out anything else first and then a dx is made on symptoms. Blood test for IBS would be a CBC with differential as knowing why your Hemoglobin level is would be important.
3. The other thought that crosses my mind re blood tests - is this Dr. testing you for H-Pylori ? Not that I think this is your problem - just brain storming.
Testing for the H. pylori infection may be performed on blood, stool, or breath samples. Also, biopsies or small bits of tissue from the lining of the gastrointestinal tract obtained during endoscopy can be tested for the presence of H. pylori. Which leads me to one last thought - did your Dr. take biopsies during your scope ?
I am sure others will be along to tag onto this thread.
Kindly,
Kitt
