I had a complete thyroidectomy in 2005 to take care of a cancerous nodule, all has been well since then. However, even though I am on replacement hormone (synthroid) monitored by my doctor, I am certain this is making it very difficult for me to lose and keep off weight. I have no symptoms of low thyroid other than the inability to lose and keep off weight - I have even been working with a nutritionist! Has any one else had this problem?View Thread
