When I was sent for my endoscopy I had to go for pre op testing at the hospital a week before. They did an EKG, blood work, checked weight, BP and maybe a few other things. I have to do the same next Thursday for WLS surgery. After that is done I have to get a medical clearance from my PCP because of my comorbidities. Maybe because you are healthy you don't need it? Good luck though!!! And tell G-Ma to chill and stop freaking you out. This surgery is safer than crossing the street.
