Hi Jaminhealth, this is Chelz. I had posted a while ago about my visit with a rheumatologist and I had brought up the issue of my weight. I had mentioned about thyroid tests and my inability to lose weight even though I have tried very hard in the past 2 years almost. I have been doing some research about thyroid issues and have learned a lot. As far as I can tell, Armour (natural) thryoid is the best one to take. Synthroid (mad made syntheic) is the one that causes more problems. Because of my nasty fibro fog, I didn't realize that my thyroid tests were taken back in 2009, my doctor had pulled them up on the computer. I did however, get a current TSH test taken just 6 months ago. Here are my results..........................what do you think? 2009 reading is: TSH 2.52 0.400 is considered low, 5.500 is considered high. My current 2010 TSH reading dropped to 1.94 Free T3 reading from 2009 was 3.8 1.8 is considered low, 4.6 is considered high. Free T4 reading from 2009 is 1.0 0.7 is considered low 1.8 is considered high. I hope this wasn't too confusing to read. Because doctors rarely discuss test results, that they consider in the normal range, I do not know if these resulsts could mean anything about my current situation. All I know is this: I have such a hard time losing the weight, my hair is getting thinner and thinner with loss, and my memory is getting much worse and I am only 45 years old. It is difficult for me to have even posted this, but I value your opinion so much, I mustered the brain power to write this, LOL. I suppose I need to get a new Free T3 and Free T4, since these two tests are old. It looks to me like the Free T4 is a little low, as well as the TSH. My new doctor only ordered the TSH, you know how it goes, they won't order T3 or T4 unless you ask them too. I have to switch primary care doctors because my current integrative doctor is just too busy giving lectures, appearing on TV, she is like a "celebrity doctor", she is not paying enough attention to her patients, never calls back when you have a question or concern. NOW, I have to find another doctor who will order the T3 and T4, geeeezzz, they look at you like you are crazy if you "ask" for these particular tests. I suppose they underestimate how much knowledge people like us who have chronic conditions really know. My sister and some of my friends didn't even know that T3 and T4 thyroid tests even existed in relation to the thyroid. Sorry I talked your head off, but thank you so much for asking for the test results. Don't know if I might or might not have a thyroid issue. Hugs and thank you, Chelz.
