The cholesterol is not likely linked to thyroid with a TSH in this range and adding T3 probably won't help the cholesterol but may be worth considering a small dose of cytomel (w/ a slight decrease in Synthroid) for the lingering hypo symptoms -- the results vary from person to person, but worth a try sometimes.
Iam curious what the DR here will say about this. But to me it seems unrelated to the thyroid - at least not directly related. Cholesterol is tricky and it has to do with steroid hormone production and fat absorbtion too - very complex - I think we cant just say that the thyroid causing it or T3 will help... usually hypothyroids have higher cholesterol - but not in all cases! There is a lot of stuff on the net on how to reduce cholesterol LDL and improve HDL - yes you already doing exercise and diet... But your body might be changing.... also some natural supplements proven well for reducing Cholesterol such as Red Yeast Rice, Niacin (I use te no flush kind), and Policosanol, CoQ10. Lots of juicing, veggies, fruits, lean protein, clean, filtered water, some whole grains, good rest and exercise should reduce your LDL and increase your HDL. I am no expert I just know what worked for me and my husband. Good luck!
