Some of my blood work came back yesterday. My Thyroxine Free level came back flagged high. It was fine prior to surgery. This would explain my extreme amount of hair loss, other than the sleeve, in general and not being able to tolerate heat at all. My doctor is thinking possibly hyperthyroidism. I am hoping that my body is just adjusting from everything that goes along with the sleeve.

Has anyone else experienced this post-op, while not having any issues with it prior to surgery?

Interesting that you are losing hair with hyperthyroidism, I thought it was with hypothyroidism, which I have had since 1995. Hair loss was a big issue for me and as one of my major symptoms. It resolved itself quickly once I went on the Synthroid. I wonder if you have had the thyroid issue prior to your surgery, but were just unaware, as these things tend to creep up very quietly? I have read that a lot of folks have (especially) hypothyroidism, but aren't aware of it, and attribute a lot of their symptoms to other things. Did you have your levels checked prior to surgery? Might want to ask about that. My sleeve surgery was 12/3/14, and as I have had the hypothyroidism AND hyperparathyroidism (including surgery for both issues), I am checked every 3 months. I have not had any changes in either case because of the sleeve surgery. Just was checked about 2 weeks ago, all is well there. The meds they prescribe for both hyper and hypo seem to take care of the issues, from what I have experienced, and from what I have heard from others, as well. Good luck to you!

I think the hair loss from losing weight amplifies the hair issue. It's really fine and brittle. So, it breaks off, giving the appearance that I am losing A LOT of hair. It is horrible. So much so, that I actually wear a wig now. My levels have been checked for the last 3 years and have been fine so far. But last week, my thyroxine free was flagged high. It's just weird.

My drs have been watching my thyroid levels creep up. Now they are 3x normal. Also have big nodule on one side if neck. Started anti thyroid med today. I am freaked out this is going to make it harder to lose weight??
