Hi; Originally I added this to the 'underactive thyroid' thread but I think it's been overlooked, so I'm reposting as a new thread: Two years ago I had results of TSH 6.15 & Free T4 14.4, which followed months of hypothyroidism symptoms. I also have a family history - mother and grandmother both had goitres. I saw an endocrinologist who decided that some of my symptoms could possibly be attributed to the side effects of a beta-blocker (Clonidine) that I'd been prescribed for menopausal symptoms. I was taken off the Clonidine and put on a low dose H.R.T. which seemed to address some symptoms and controlled my hot flushes. Recently, I felt that the hypothyroidism symptoms were back with a vengeance; exhaustion, lack of energy, insomnia, constipation, dry skin, dry and breaking hair, etc., so I've just had another blood test and the results fell with the normal range (TSH 2.64 & T4 14.5). However, my G.P called me in to tell me that I have elevated antibodies and that this almost certainly means I will become hypothyroid at some point. She's going to do some research and let me know if I need any treatment. My own initial research suggests that I have Hashimoto's Thyroiditis and that treatment with Levthyroxine could control it and prevent future problems but that doctors rarely treat it unless the patient's TSH level are also elevated. Does anyone have any helpful advice, information or experience to share?
