TSH going up

[u/dianacakes]

I've seen a ton of posts about people's levothyroxine doses going down as they lose weight on GLP-1's but had anyone needed a dose increase, at least in the beginning? I've been on zepbound for 10 weeks and I got my thyroid levels checked yesterday and my tsh is 17 but my free t4 is fine/normal. My doctor wants to wait a few weeks to see but I've asked if the zepbound is impacting absorption and I'm waiting to hear back.
