Hi, Dr. Smith and mrsD:

Dr. Smith, you talked about hypogonadism in one of your previous messages in this thread. I am not sure if I understood you and the documents from your links right, but may I ask you if opioids can cause hypothyroidism? If you already answered this question, please excuse me for asking again; my memory is not what it used to be since I got my head trauma in August 2001. Another question: what do you think about the pain killing effects of natural progesterone taken in capsule form, since again, my body is not making any?

MrsD, I have to take levothyroxine (right now, at the dosage of one 25 mcg tablet once daily) for the rest of my life, because my thyroid has an auto-immune disease (thyroiditis), which I read in some web sites could lead to hypothyroidism. I also read in these web sites that thyroiditis is another name for Hashimoto's hypothyroidism. Can taking levothyroxine in tablet form for the rest of my life give me cancer?

Thank you both for your information.
