    Was Hypo, now low TSH, High FT3

    I was DX Hypo in 2007, fine until 12/10 now dealing with swinging symptoms, Hypo to Hyper, with all the Hypo symptoms. Hair loss, weight gain(17lbs in 2 months), fatigue, insomnia, horrible night sweats.....seeing a NMD who can't seem to figure this out.

    Labs: 08/15/2011
    TSH <0.01 Range (0.36-3.74)
    FT3 12.52 Range (2.18-3.98)
    FT4 1.18 Range (0.76-1.46)

    Labs: 03/21/2011
    TSH 2.81
    FT3 3.21
    FT4 1.08

    Taking 1.75mcg Synthroid, which has been adjusted over the past 2 years.

    Please help!

    Thx MG,

    Just had TPO & TyAB done.

    TPO 1330 range <less than 20
    TyAB 61 range 0-60
    FT4 is now low, FT3 mid-range, TSH still 0.01

    Still losing hair and gaining weight despite running 4-6 miles per day and eating like a bird. Insomnia, racing heart, etc.

    Seeing a Endocrinologist in 2 weeks. Any thoughts?

    Re: Was Hypo, now low TSH, High FT3

    This is really odd behavior, it happened to me with untreated Graves and Hashimoto's.

    I really think you need the full antibody panel. You are not post menopausal so the low T4 and mid range T3 warrant supplementation. How low is your T4? My MD was able to recognize my adrenal function issues by my FT3 levels being 20-40% higher than my FT4 levels.

    But I am still confused that on 175 mcgs that you are so low I'm both now. I wonder if something is causing thyroid hormone resistance or if you have developed RT3 conversion issues to protect yourself from hyperT3.

    You and your Endo have a lot of work to do. I hope he runs a RT3, T3 Uptake, and an adrenal panel. I think that there is more going on than just your thyroid. I am not an MD but the chemistry behind it doesn't make sense.

    I am glad you are going back to the doctor hopefully he will have some better ideas. Let us know how it goes, okay?

    If we learn by our mistakes, I am working on one hell of an education.
