How Many Of You Suffer From Hyperthroidism? in Related Issues & Disorders Posted March 23, 2009 · Report to Admin I don't know what is wrong with my thyroid... My doctor is scratching his head about it , as well.. My T3 levels have dipped even lower, after taking tapazole.. My TSh is currently 0.04.. What is wrong with me??? I hope by now you are feeling better...Is your TSH at .04...or does it say <.04? <.04 means it is less than .04 which is the least your particular lab can detect. That means your TSH is unmeasurable. What are your lab ranges and free T3 and free T4...do you know? Do you have reverse T3 numbers? Hyperthyroidism is extremely dangerous. Before the introduction of anti-thyroid drugs like Tapazole (methimazole) and PPU, there was only a 50% survival rate. It is expected that your free T3 should fall on Tapazole...you have too much of it, which is why your metabolism is too fast and your weight is too low. Are you seeing an endocrinologist? In the case of hyperthyroidism, you don't want to monkey around with a GP, this is serious stuff. I have both Hashimotos and Graves' disease, high antibodies for both (TPO and TSI). After seven years on a gluten-free diet (biopsy diagnosed as of May 1, 2002) my thyroid issues haven't resolved, and I bounce back and forth between hyper and hypo. I'm going to finally have it surgically removed next month, and can't wait to be on an even keel again! I have a wonderful naturopath who will put me on Armour (have been on it when hypo) and am looking forward to getting my life back. Allow me to suggest another site for thyroid disease research. Mary Shomon publishes books on thyroid disease distributed in mainstream outlets (Borders, Barnes and Noble, etc.) and runs this wonderful site that can help you in educating yourself about thyroid disease: http://thyroid.about.com/ To the person who mentioned gaining weight when hyper...happens to me too. My appetite gets hotter than my metabolism. It isn't that rare, but can make it hard to suspect hyperthyroidism and get a diagnosis. Conversely, my son, who does not show antibodies for either Hashis or Graves' has low T3, and is doing very well on cytomel. He is 19, and at six foot four, only weighs 135 lbs. This after gaining 15 pounds on Cytomel! So his hypothyroidism caused him to be too skinny due to lack of appetite. It also caused some terrible emotional issues he had to deal with for his entire childhood. He is doing much much better now, thank goodness. Good luck to you both, and make sure you get the proper treatment. An endocrinologist is absolutely a must for hyperthyroidism...it can kill you. Kit in St. Louis.
