I recently had my thyroid tested and my doctor said its just in the normal range but my brain is having to work a lot harder at getting it to work. Does anyone know what that means? Should I be concerned?

You really should get a print out of your results with the ranges. 'In the normal range' means nothing. Yes, you should be very concerned!

What you should do, in my opinion, is ask for the actual test results as numbers - and their reference ranges. We all know blood tests are far from perfect, but they are often all we have to begin with.

Thank you for answering. I've been getting a lot of the symptoms for hypothyroidism and I need answers. So thank you very much.
Hi First make sure that you have had a test for TSH, T4 and importantly FT3. Doctors sometimes only do TSH now, cost but these 3 together with how you feel are essential.
Best wishes,

I've been posting this example by Dr. Rind:
When’s the last time you went to the doctor and gave a blood sample – that was then sent to a lab? Chances are that lab result came back ‘normal’. Too often, when interpreting lab values, the doctor looks for normal rather than optimal.
A comparison of values relative to each other yields a great deal of information that would be lost if the values were viewed independently of each other. For example, if the normal height for a man is between 5’3” and 6’ and normal weight is between 130 lbs and 200 lbs., scanning the results column of a lab or other report (for flagged abnormal values) would declare a man who is 5’3” tall weighing 200 lbs to be just as normal as a man 6’ tall weighing 135 lbs. Both are in the ‘normal’ range and therefore would be considered normal. In reality, however, simply looking at a short/obese man next to a tall/thin and a possibly undernourished man would suggest that the two are more than likely not in the same state of health.
