Broken metabolism after WLS? Might be your thyroid!

 I just learned I have too much Reverse T3, which is keeping me hypothyroid in spite of increasing my Armour thyroid dose (Armour has celloluse now, which could be making it harder for me to absorb as well. I might need to change medications). 

I've been doing a lot of research on the web and came across this site:

http://nahypothyroidism.org/deiodinases/

If you scroll down to the part titled, "Dieting/Weight loss/Obesity/Insulin Resistance," it discusses a little about what dieting does to T3 levels in the body, and how that causes a lowered metabolism. You might, however, want to read the beginning to get a bit of an explanation of what a deiodinase enzyme is. Don't ask me, I'm still trying to get a grasp on it myself. :)

So what I want to know is, should I accept the fact that my metabolism is low because of my gastric bypass? Or can I counteract this problem by treating my hypothyroidism correctly?

Hmmm...

PS: The discussion on Leptin is interesting as well. You might want to read that. 

I don't know how to answer your question, but I do know caloric depravation screws up your metabolism.

I was born with a broken metabolism. My DS fixed that. Any news on getting your revision?

We need specific enzymes to convert T4 to T3. If there is not enough, or with so many other factors - it gets converted into rT3. 
I know there are a lot of minerals that are needed for the proper conversion. One of them is selenium. I know once I introduces more (natural) selenium to my supplements (Brazil nuts, nuts) My T3 increased and rT3 decreased.
There is also the thyroid -iron connection, and the thyroid -insulin, and thyroid-estrogen connection.   And since post op RNy our hormones are all messed up - you we are "screwed" roughly put it. 
Good luck to trying to figure out ....
I do not have hypothyroid, but I do have sub clinical case - theoretically my numbers are O****il you start checking the T3 and rT3.  I have been working hard to increase the T3.
