In regards to the question about what tests to get - when I got onto a good GP, she tested:
Sex hormones (testosterone, estrogen, progresterone)
SHBG (sex hormone binding globulin)
Iron - ferritin, saturation, iron
Blood Glucose (fasting)/Insulin
Lipids and HDL etc
Full blood count
I was resistant to T4 - even though my TSH was low, and t4 levels were 'good', so technically I was 'not hypothyroid', my t3 was below range, and my rt3 was very high. Once you took into the fact I had very little active thyroid hormone (t3), and was turning all my t4 into something that blocked the action of t3 (rt3), i was quite hypothyroid. I gained and gained in spite of eating very little.
It has taken me almost two years to get onto the right meds, so don't give up!
The OP and I cleared up the misunderstanding about the cookies a couple of pages back. Seems like the only feathers still ruffled are yours. No idea why.
The fear mongering I was referring to was not this thread in particular but , as I said, an internet meme, popular on sites such as those of the various Peat disciples.
I'm not "chastising" anyone (although I did tell Zach to bite me which he richly deserved for the Inuit/shark comment ). I have said on this forum REPEATEDLY that I have no problem with whatever macronutrient ratio a person chooses for him/herself. I do have a problem with scientifically unfounded statements such as "low carb will wreck your thyroid" being circulated AGAIN.
My sisters hair is falling out now from pneumonia in sept of last year. Definitely can be delayed. She lost more than half. She had exceptionally thick hair to start with though.
In my 30s I ate less than 100 grams of carbs a day. As a result, I had hair loss (one ID showed a half inch of missing hair at the part), acne, fatigue and generalized stress. From age 33-40 I took the bcp to shut my ovaries down so I could sleep and basically function. Estrogen has a suppressive effect on the thyroid-- be aware that if you continue to eat low carb, you will probably have early perimenopause symptoms.
Interesting thread. I am going through this right now. My hair is still falling out in handfuls. My naturopath is currently changing my meds to a compounded 3-1 t4/t3 ratio. I have been on synthroid for years, but never thought it did anything for me. Then on Erfa in increasing dosages, which helped temporarily. Starting tomorrow, the compounded. I have also been reading about Wilson's thyroid protocol which is interesting. My temp is always low. Usually around 35.3c. My free t3 is also clinically low.
Primal, minus eggs, dairy and a myriad of other allergens.
I had to bring pictures to a doctors office and that was when someone finally understood something was going on.
I am interested in this thread too, because I have some conversion problem and I didn't feel right for a couple of months.
My doctors don't see it as a big problem and don't address it. I've made some changes - reduced consumption of kale, increased intake of carbs (I possibly went too low), increased intake of red meat (I possibly was low in iron after a blood donation), etc.
BTW, Kharrazian mentions numerous causes for poor conversion.
I didn't have such a thorough testing (which would help), but I am OK now. I'll ask for a couple of tests (ferritin, for example) at the next opportunity (May?). I don't think it's an emergency now.
