I met my surgeon in April 2014. I had blood work, sleep apnea test, six minute walk pulmonary test, pulmonary fitness test, chest X Ray, Ultrasound of stomach, ENG, and Stress test in June and July 2014. I have been seeing a nutritionist since July monthly. I think tests are necessary and vital before surgery. I am scheduled for November 4th. But I still have Psychological tests and nutritional goals to be ready by November 4th. I think you should ask your Doctor and consult others. This is your life, right?
