Hello....first time poster here.
I've started the process to have a consultation with a surgeon for Gastric sleeve surgery. As of now, I'm about 5 lbs short of 40 BMI, and have absolutely no co-morbids. I've watched the educational video and have received their information packet in the mail. I have been eating and trying to gain weight (which sounds completely counter-intuitive) because I REALLY want to have surgery. I had started the process twice before...actually had the psych eval, and went through 6 months of medically supervised weight loss, and tried every diet known to man. I got discouraged with the medically supervised weight loss because I plateau'd for several weeks and then despite changes, I actually gained weight. None of that program was covered by my insurance, so when they said I needed to come in more often (3x/week instead of once every 2 weeks), I just stopped.
I had always thought I was 5'1" but at my most recent doctor's appointment they said 152CM, which comes out to 4' 11-3/4". Current weight is 201.5, which all calculates out to BMI 39.6. I've held off on taking the next steps in the packet because I'm not yet 40 BMI.
My insurance is BC/BS Federal employees...anyone have experience with them? What happens if I get approved and then lose weight on the 2 week diet? I'm going to barely qualify as it is.
Anxiety level is very high, but I want to do this. I'm sick of hating every picture I see of myself, and constantly being tired from lugging around 85 extra pounds. (sigh). I'm most concerned about not qualifying on insurance. Any encouragement would be very welcome.... Thanks!
