The process starts with you having a consultation with your GI(Gastrointestinal/Gastroenterologist) doctor. This is usually just a meet & greet type of session. They might feel around your abdomen to check for signs of pain. They’ll then probably want to schedule a time to do the procedure. In some cases, if you also have upper digestion problems, they may also want to do an upper endoscopy on your stomach(EGD). You may have your own stigma attached to which of these triggers more of a fear. For me, I have Emetophobia(fear of being sick to your stomach) and an EGD was much more terrifying to me than a colonoscopy, I still had it done though & indeed survived.
