No that's incorrect the dr referred me, then I was asked to attend a group seminar at the hospital I was to have op at. Our heights and weights were then taken. I was then seen by a dietician a few month later and set a weight loss target if 7lb and asked to quit smoking. Next appointment was with consultant I had lost 2 stone and had quit the fags. I then moved further with the process onto endoscopy If I had not lost weight I would have been sent away and asked to try harder to show commitment. After the endo I got onto the waiting list and had to maintain weight loss. in the 18 month from referral I have lost 3 stone. MDT is multidisciplinary team were your case is discussed ! Hope that helps x
