What about the reference ranges? Particularly FT4. As reference ranges vary from lab to lab a number on it's own has no meaning, it's where in the range you fall that matters.
The aim of a hypo patient generally is for TSH to be 1 or below and FT4 and FT3 to be in the upper part of their respective reference ranges if that is where you feel well.
Your TSH is fairly close to that but we have no idea where your FT4 lies, and FT3 would complete the picture as we would be able to see whether you are converting T4 to T3 well enough.
Ferritin is important because thyroid hormone can't work unless it is a minimum of 70 and half way through it's range is recommended.
All vitamins and minerals need to be at optimal levels (not just in range) for us Hypos and low nutrients bring their own symptoms too.
Creatinine tells us how well our kidneys are working.
So your results don't tell us much. What you really need is a full thyroid profile plus vitamins and minerals as mentioned in my first reply above. The private fingerprick tests I linked to above will give the whole picture and once you have all those results you should have a clue as to why you are tired and can't lose weight. My guess is possibly low T3, especially as you are exercising so much. It has been explained by other members that exercise will deplete T3 and if your T3 is already low then exercising will mean that it will be even lower. T3 is very important, it is the active hormone converted from the pro hormone T4, and every cell in our body needs T3.
