Hello, I have been on Levothyroxine for about a year. I was initially diagnosed with a connective tissue disorder and prescribed hydroxychloroquine, but this had little efffect. I was also sent for CBT, which annoyed me more than anything, as they were suggesting I was imagining the pain/weightgain and it was psychological.
Initially, not much happened on the levo, but then I read that progesterone has an impact on the thyroid's function. This was a bit of a light bulb moment, as my symptoms had coincided not only with getting a nasty infection (which is what I thought was the cause of everything going wrong), but also with me stopping the progesterone only pill (POP) after taking it for many years. It never occurred to me that it might have been the Pill keeping me well (or keeping my thyroid supported).
To cut a long story as short as I can, when I first fell ill (after getting an awful UTI in Kefalonia but also stopping the Pill at the same time), I rapidly developed aches and pains, very painful joints, stiffness and pain in my ribs and gained 2 stone within 2 months, but had changed nothing in my lifestyle. After eventually getting a low thyroid diagnosis I was put on a low T4 dose (50mcg) and not much happened. Increased to 100mcg and still not amazing but my aches started to improve. As soon as I started the POP again, all the pain and fatigue disappeared, my husband said I was like my old self again and even his family commented that they had the old me back, and, incredibly, I lost a stone within a month (without trying and for the first time in 5 long years of diets and exercise plans all to no avail). The weight-loss was rapid but stopped abruptly at one stone and I was still a stone overweight.
Anyway, I still take the Pill and T4 (100mcg) and have been adding Uni Pharma Thiroyd (from Thailand) that I bought online from Amazon - I know, please don't tell me off, I was/am desperate. I also take a thyroid supplement and D3.
*After* I started self-medicating, the endo tested me and my T3 was still in range but mid-to-high, despite being heavily over-medicated (which I admitted to the endo - I expected my levels to be way higher), my TSH was "suppressed" but my T4 was still very low in range (I think it was 12.2 and the reference range was 12.0-22 or similar). I actually felt pretty good and all my aches and pains disappeared, I didn't feel as tired (and I have a toddler, so I am usually tired anyway!) and I was starting to feel that all was not lost.
I started the additional Thiroyd on a very low dose, by crushing them and using a tiny amount, but I found it made no difference at all. I increased and increased and am now taking arguably far too much, but it has made absolutely no difference to me. My weight has now gradually crept back up by about 7lbs (so I am still a little less than I was before I went back on the Pill, but heavier than I was when the weight initially dropped off) and I can't seem to lose it again. I'm achy and tired again and my joints are sore. I feel as though my body has said, "Great, finally, some thyroid hormone, huzzah!!", but then it had a bit of a regroup and now thinks, "Actually, that's not really doing it for me anymore."
I'm sorry, that's a really long way of asking, can your body get used to a dose of medication and then need more as a result? Like fitness? When you start out exercising, it kills you to run to the end of the road but after a while you adjust and then need to run much further to have the same level of improvement.
I don't know what to do anymore, because the endo told me, after the last tests mentioned above, to stop the NDT and reduce my T4 to 75mcg, because I had clearly improved so much and didn't need it anymore (I don't think that's how the thyroid works). He said that because my TSH was suppressed I was in danger of a heart attack and even showing him thyroid books and prints outs about TSH and needing to look at the other results wouldn't change his mind. Luckily, my GP had more knowledge and let me go back to 100mcg.
Anyway, I am frightened of continuing to take the NDT because know I am taking too much (or it might just be a duff batch or a fake one for all I know, how can you ever be sure when you're buying online??), but I am not seeming to respond to the T4 or the NDT so much anymore, despite a brief improvement after starting the Pill again. I've had no overactive symptoms at all so I am at a loss really.
Sorry for a massive ramble.
