I had the bypass on March 4th and have been having some post surgery issues. I have constipation for about three days followed by diarrhea and throwing up to the point that I actually pass out. I have had an endoscopy and a CT scan and nothing. I also had an appointment with an ENT and nothing. Cardiologist says nothing going on with my heart and my sugar level is not dropping. Reaching out in this forum in the hopes that someone else has experienced this and can offer help.
