My a1c levels for the past two check ups were 5.7. So basically my diabetes is manageable. Would you take diabetes into consideartion  for WLS with these numbers?

Work closely with an endocrinologist or diabetic educator!  You may not need the pump, but even if you do, your insulin needs will change.  It's important to be proactive so you know how to manage this part. 

Rooting for you!!  YAY!

Well, these were ALL my concerns and questions two years ago before RNY.  I am a type 1 and was not on a pump (am now), but on multiple daily injections.  Lots and lots of questions and fears about the issues you raised.

First, you likely will be fine.  Because you will be eating so little initially, your insulin needs will be much less than they are now.  I would STRONGLY recommend that you have a consultation in the hospital with an endo and that the doctor follows you while you are in the hospital. Then, you should schedule an appointment with your endocrinologist for as soon as you are discharged, so that you can work closely on a plan that will work for YOU.  I was fortunate as my endo gave me his cell #, and we texted in the hospital and he saw me the day after I was discharged.  Demand attention - you will need it, as you likely will need to make big changes in your basal rates when you reconnect to your pump.

Secondly, and most importantly, you will need VERY LITTLE to bring you up again should you go low.  And you can have liquids, so a little juice or milk will be fine to bring you up.  Honestly.  What you are used to now is probably way too many carbs - and about an ounce of juice will fix your low (and will not cause dumping because it is such a small amount, so don't worry about that).  You should also have glucagon around in case of a big emergency.  I did, but honestly, I did not need it at all.

Frankly, lows will not be a problem in the early weeks.  In order to get all of your protein and fluid in, you will have calories going in constantly - all day long.  In fact, you might drift a little higher because of that.  And, you and your endocrinologist may decide that running a little high temporarily is better than running low.  I am used to eating three times a day and those early weeks were tough because you are taking in calories/liquid constantly. Because you are on a pump, you have the ability to make very fine adjustments hourly if needed.  Take advantage of that and work closely with an endocrinologist to manage.

They will monitor your blood sugars during surgery and will address any problems.  I emphasized with everyone, including the anesthesiologist, that I wanted this done.  And they will do it.  I know it's hard to turn that over to someone else, but it will be OK.

I am sure you will be fine.  But, truly, I understand since I went through this exact thing two years ago.  Just be assertive - oh, and take your pump and meter with you.  Once your surgery is completed and you are awake, they will likely allow you to hook up again.  I had my gall bladder out last year (and RNY two years ago) and, both times, they allowed me to run my own medicines and decide what I needed when.  Since I have 25+ years at it, they realized that I knew more about how my body works than they did.

Congrats on this big step and please ask any questions and let us know how you are doing!

Good luck!

I had the same problem with my diabetes.  My A1C was 15.5 and I went to and endocrinologist.  It was the best thing I've ever done!  He put me on Novolog before each meal because it is a fast acting insulin.  Then I take Levemir in a small dose in the morning so that it will stay in my system all day and a larger dose to get me through the night.  Your A1C should be checked every 3 months for an average.  Within three months I was down to 7.4.  I go back next week to be tested again and I feel certain it will be lower.  My surgeon will not operate if it goes any higher.  I adjust my insulin according to what I eat.  That's what helps my A1C level reading.  I am unable to drop any weight because my nutritionist said I take so much insulin, which isn't my fault.  Insulin that isn't used by your body is stored in your fat cells.  Therefore, I'm unable to loose the weight.  My doctor feels that once I have the surgery I should be diabetes free.  WooHoo!  I hope that this helps you in some way.  I would suggest you see an endocrinologist asap to get your sugar under control.  I would hope that it might help you as it did me.  I hope this helps and  I am wishing you the best!  Hang in there!
