Thyroid adjustment after weight loss

I was slightly hypothyroid with levels of 4.15-4.31 with some symptoms. My endo put me on 88mcg of Synthroid and my doctor checked my levels 8 weeks later and called in said I was okay at tsh of. 0.31 my question is as someone who currently cutting should I get my levels re checked after losing weight or every 10 or 20lb of weight loss ? Also should I check then when im in a leaning mass phase and gain weight ?

If your “maintenance dose” has been identified, you should be getting annual TSH monitoring anyway, but it’s certainly reasonable to check more frequently as you make changes like that as well.

Thank you , I’ll get it check again when I’m done cutting just in case . I do sweat a lot lore then usual now .
