Believe it or not, this is one of our diagnostic questions we ask our patients. It goes something like this, “Sarah, let say it’s a Sunday afternoon and you sit down on the couch to read a good book. How long can you keep reading until you start nodding off?” The answer, so many times, is, “Oh, maybe 5 minutes, at the longest. That’s why I just don’t read that much anymore. I just can’t concentrate.” That is one of the cardinal signs of a person with a thyroid problem.
