Hi everyone,
Looking for advice.
I have recently had my thyroid tested and have results of TSH 3.1 and Free T4 at 15.
My doctor is saying this is normal but I feel anything but normal. I am always tired, suffer with lack of concentration, brain fog, heavy periods (have been tested and had surgery for endometriosis - nothing found). I also struggle to loose weight no matter what I try.
Am I actually hypo? or am I normal?
Thanks in advance.

A TSH of 3.1 shows that your thyroid is struggling but wont get you a diagnosis unfortunately.
Do you have the range for FT4, ranges vary from lab to lab and there's no way of knowing if yours is low or high. My GP's lab range is 7-17, yet we often see 9-19 and 12-22, so we can't interpret your result without the range from your lab.
Unfortunately, TSH and FT4 aren't the full picture. FT3 would be useful, so would thyroid antibodies - Thyroid Peroxidase and Thyroglobulin and if either of those antibodies are raised then you are looking at autoimmune thyroid disease (aka Hashimoto's) which is where antibodies attack and gradually destroy the thyroid.
