I posted on another board and thought I would try here too! I had RNY in May of 2007.  I am now suffering from episodes of low blood sugars.  I was never diabetic before surgery.  I can have drops with or without food.  I have a wonderful endocrinologist who has done a lot of testing and it is Reactive Hypoglycemia.  She wants me to try Precose to eliminate or control the low blood sugar levels.  Have any of used Precose?  How did you react to it?  Did it help?

Hi,
Yeah... Sounds like more surgery is putting the cart before the horse. I think you have more to check out. Doesn't seem they have ruled everything else out as in "differential diagnoses."
If during any testing, they can't view the entire digestive tract, things may be missed. So, you ask them what would be the best way to look at the entire DT.The DBE I mentioned is a good way. This must be done by an endoscopist with a good amount of experience. I had two performed by an internationally renowned Dr in L.A., Ca.
I was told the bacteria couldn't be swabbed due to other contamination caused by stuff in the bowel. Systemic Tx of SIBO is performed using antibiotics absorbed into the blood v.s. Xifaxin which only works when it mechanically comes in direct contact with bacteria and it's not absorbed systemically into the blood. Since Xifaxin can't get into the blind loop, it can't kill anything there. Good luck.

I hope you went and talked to the doc.
it can be anything. Even the hernia back again. (that happened to me..) I had hernia repair and 2 weeks later the hernia was back.  I know that for sure since 10 months later (leaving with pain on and off)  I had another surgery and another hernia was found and fixed.
It also can be an ulcer... or you may need some good bacteria .... During surgery - they usually give us antibiotics (to prevent infections) and that will kill the friendly bacteria. 

I hope you went to see a doc.  If that was ulcer(s) - it can be treated. 

I just saw your reply, thanks so much.  I actually did go see Dr Nizzi and just said I know my body and something isn't right.  So next Tuesday Jan 24th I am getting a EGJ (scope) to look for ulcers and I was wondering if they could swab for bacteria then too??  Also all your natural health doctors talk about yeast overgrowth??  Then in Feb I'm scheduled for laproscopy to go in through my original incisions to look for anything else, scar tissue, hernia, obstructions, I guess??  Any other suggestions?

 Hello,

Sorry to meet you on this board.  It would take me an hour to describe my post-op journey of constant illnesses.  My doc did try or at least listened to me for 1 year but yr 2 I knew he'd lost interest.  I stayed away for a yr because I was disgusted and had so many problems that other docs tried to help me with but none of them saw any link to my RNY either.  Finally had ER crises (big open exploratory surgery) and was scoped post-op.  Found a "huge" ulcer at the anastomosis.  Sent away with PPI Rx and a "we'll re-scope in 3 months".  Only that PPI and the next 3 others caused a bizarre mouth syndrome (loss of all taste, painful burning of tongue and roof of mouth, and thin skin that tore easily).  The carafate (Rx that coats the GI tract) made getting liquids down much easier but carafate also blocks calories and nutrients.  I am wasting away.  Any have been since Day 1.

Re-scoped Wed and now ulcer is a bleeding ulcer that has eroded so deep that 2 arteries are exposed.  They clamped those and said "let's try PPI # 4 and hope it is the charm".

Opinions - I want to have a feeding tube put in so that 1) the ulcer can rest and heal (maybe) and 2) I can finally get some calories and nutrients.  

I'm truly afraid of these docs by now.  I know if this goes on, 1) my ulcer will perforate or 2) I'll face a big surgery to remove all of the diseased tissues and so on.  And if I don't tolerate PPI's at ulcer prevention levels, why would I do so after that?

What do you think?  Anyone?
