Congratulations! Many people's type 2 diabetes goes away in no time, and blood pressure stabilizes. It won't fix all your health problems because you will still have to monitor the nutritional blood numbers regularly. As for self esteem I would recommend counseling and journaling. Start everything now like vitamins, protein and water before surgery so you can focus more on your recovery. The people who are prepared and start early do not usually experience buyers remorse of the post op emotions Good for you for making healthy choices!

4 1/2 years out from my sleeve and I'm so glad I did it. It's OK to be nervous, wouldn't be normal if we weren't, but follow your program, and it will go well.
I agree with starting to sip water all day, get your vitamins in now (they will help you heal better too), and eat your proteins first. You'll be learning new ways to live afterward, and the better practiced you are heading into it, the easier it will go.
Good luck and let us know how things go with the surgery.

I got an RNY in 2012. No regrets what ever!
It is normal to have the jitters before surgery. Just keep your eyes on your goal. The pre op was the hardest part for me.

I don't know much about the sleeve. But if you stick to your plan all Will be well. Just keep thinking about how great it's going to be when the numbers start tumbling down!

The improvement in health besides the weight loss are wonderful too! You will feel better and get around better. I WAS a type 2 diabetic. I was taking 5 to 7 shots of insulin per day as well as metformin. After surgery the diabetes is GONE! No insulin no nothing!

Hope some of this encourages you a little. This type of surgery is a life saver!

Congratulations on your decision to get healthy! Keep us posted on your progress.
