Mine was a little over a month - I met with the surgeon on May 2nd and finished all of my Pre-op clearances (blood work, H. Pylori test, NUT consult, letter from my primary doc station my weight loss attempts and joined a bariatric resource program my employer required) by May 10th - it was submitted to insurance that day. I had my sleep study to rule out sleep apnea on May 15th while waiting to hear from insurance. Insurance approved the surgery on May 20th - they scheduled my surgery on May 23rd for tomorrow, June 5th and I started my all liquid Pre-op diet on Sunday, May 26th. I did all of my Pre-admission testing etc last Wednesday the 29th - bloodwork, respiratory consult, X-rays, ultrasound, EKG, another NUT consult and meeting with medical doctor who cleared me for surgery (about a 3.5 hour appt). And here I am now - surgery tomorrow (I need to be there at 12:15 and surgery is scheduled for 1:45). I was very lucky though that I didn't have to do any other supervised diets or NUT consults...
