I was diagnosed with Graves almost a year ago and had RAI over the summer. I've been on levothyroxine for about four months, currently 100 mcg. I just had lab tests the other day, and unless I'm mistaken my levels are all within the normal range now. However, I also was tested for glutamate and cholesterol. My glutamate was at the upper range of normal, and for the first time in my life (I'm in my 60s), my cholesterol was above average. Could there be a connection with the thyroid problems? I don't think I've significantly changed any aspects of my lifestyle that might have caused the spike in cholesterol in particular. I'm seeing a new endocrinologist in a few days (the doctor who ordered the lab tests was an internist, also new to me, due to some insurance changes). I'm sure she'll be able to address any associations between all of these other potential chronic health problems, but just wondering while I wait.
