Hi folks, I've posted here before about my own problems with hypothyroidism and no thyroid gland and your comments were extremely helpful. Today the problem is not mine but my sister-in-law. She suffers from Miasthenia Gravis but also from hypothyroidism, although she still has a functioning thyroid gland. She is currently on 25 mcg of levothyroxine but is suffering badly with anxiety, causing lack of sleep. She obtained her bloods from a recent test and having seen the results I am surprised at the reaction from her GP. The only test that was done was the TSH, nothing else was tested for, no T4 or anything else that may contribute to her symptoms. Her result was 4.7 on TSH. I suggested that she see her GP and tell her that she has sought advice and that her dose is far too low and needs increasing to bring her down to the lower end of the scale. Do any of you have any other advice that I can pass on as she is getting desperate and it would appear that her GP is not very experienced with thyroid problems? Should she request a full blood test taking into account things like liver function, haemoglobin and ferritin levels and also her T4 reading or am I not knowledgeable enough. Thanks for any advice that you can give.
