I am a 65 year old male. Over 10 years ago I had a partial thyroidectomy with the left lobe being removed. No cancer found. For a few years I did not take medication. When a TSH test was high my doctor put me on 25mcg of synthroid. A few years later when it was high again the dose was doubled to 50mcg. That dose has been sufficient until my last blood test 6 months ago showed a high TSH of 4.95. My doctor decided against raising the dosage. Over the past couple of months I've had a few episodes where I wake up in the morning feeling light-headed/mildly dizzy/foggy. Sometimes it goes away in a few hours but it has lasted all day as well. I'm able to go to work but just don't feel right. I've also gained weight over the years even though I bicycle up to 100 miles/week. Just wondering if anyone else has experienced these symptoms? What would be considered the optimal TSH level for a man my age?View Thread
