RNY VS DS

Well thank you all for your insights - especially Lady.  Quite comprehensive.  I guess I do owe you a Little of my history though. I live in Houston, Texas 6 minutes from the Texas Medical Center.  I am 65 years old, BMI of 51, a new Medicare patient with a little high blood pressure and sleep apnea diagnosed years ago and apparently gone now.  No diabetes or high cholesterol or other issues. Dec. 2009 I had a lap band that failed miserably. I gave it my all but the follow up by True Results was dismal.  I wore myself out calling for advice and guidance and it was all conflicting information between the staff.  Eat 400 calories daily.  Oops starvation mode so eat 1,000 calories daily.  Exercise is imperative.  Well don't exercise and concentrate on diet and water.  So I lost 40 lbs and finally just flat gave up.  Just terrible. I paid $13,000 of my money as then my insurance, Cigna, excluded all WLS.  The whole family waited for the big loss but nothing.  I felt the fool. Duped.  So my husband said wait on Medicare and go round 2.  So Medicare is here and I am covered by it and AARP Plan F and a drug plan.  Now decision time.  Medicare pays for DS too.  I was thrilled to be accepted at Methodist by their high risk surgeon.  I am not high risk but he saved my Dad's life a few years ago and I have great faith in this man and his skills.  They say they have people who come to him with major health problems who were turned down by other docs due to their high risk issues and he takes them all and has not lost a one. So I am set.  Then DS appears.  I have a friend who is a medical professional now on the team of the DS doc.  So I emailed her for advice on this surgery.  She told me 3 years ago not to do the lap band and I ignored her.  Of course she proved right. So I am thinking she will be right this time too.  I won't ignore her though.  She said not to even consider it.  She said "Lots of problems with that one.  You might be signing on for a lifetime of diarrhea."  That didn't sound so appealing. so I posted this advice from this medical professional to the DS folks asking their opinion and those guys got plenty defensive.  I was looking for honesty.  I got attacked.  So I came back here for a more reasonable assessment.  Thanks for your advice.  No DS for this girl!  I am haunted by that lap failure and don't want another failure.  I will be done with the 3 month Weight Management Program mid November, have been attending monthly support groups voluntarily, have all paperwork in from True Results (the Op Report), years of history from the primary care and her agreement to send the letter recommending this WLS.  I am going to her Oct 22 for all pre op tests, the doctor Oct 29 for my visit, finishing the Weight Management Program mid November then I guess approval and a surgery date.  Medicare has already said it is a go when all paperwork is to them.  So it is Go Time I guess. Yikes!!!!!  I guess I am panicky like everyone is.  Oh well I got myself into this and now I have to get myself out.
