My insurance requires the existence of 2 comorbidities if the BMI is < 40. Sleep apnea is one of the comorbidities that they consider. I had a sleep study as it was my last possible option to getting approved by insurance... BMI of 35, high cholesterol, and otherwise healthy... unless you consider depression, arthritis (knees), back pain, etc...
My doctor recently added EGD to his protocol. When I had my pre-op appt for the EGD, couple of weeks ago, yet my EGD isn't until the end of August, I asked him why... Basically, it comes down to his experience in the procedure and better patient recovery.
