I have Hypothyroidism as a result of Hashimoto's. I'm affraid my metabolism is going to be stunted because of the effects of absorbtion of the pills i take. I know I'm seeing an endocrinologist, but my anxiety around it is I've done this surgery for nothing. I've lost about 26lbs the past 3 weeks (post surgery) which feels great, but with a goal weight of 130 (I'm currently 201), it feels impossible with this standing in my way. Any advice?

Your endocrinologist is probably going to keep a close watch on your TSH. You might have to have your levothyroxine dosage adjusted throughout your weight loss. But I image once you become weight stable your TSH level should become stable also and you won't have to get tested as often.

I'm getting a revision from a failed lap band to a RNY and am also curious how it will affect my hypothyroidism.

Good luck--I'm sure your endocrinologist will be right on it!
