What is the cause?

Anyone has any idea of how thyroid is caused?

Some time people have a slow thyroid or other problems, I my self have never had any problems. But I do read a lot. There are medications for thyroid problems out there. Talk with your doctor if you think that you are having problems, that is always the best answer. I'm sure that some one else here will be able to help you more.

You could add more to your question, to help explain what problem with the thyroid you are talking about, possibly having.
Is there a cure for it?
