I'm 9 weeks pp, and currently breastfeeding. I'm on levothyroxine for being hypothyroid. This was discovered by my usual endocrinologist in the US, and he has overseen my treatment and my GP surgery here has always been happy to oblige. A couple of weeks ago I had my test results and the GP said to lower my dose. I sent the results to my endocrinologist who said I shouldn't as I'm still breastfeeding and it's best to keep them that way. I'm on two kinds about it because usually I come back with my own set of bloods done and the endocrinologists advice but this time they've both seen the same results and it would be the opinion of one against the other. I feel like my endocrinologist knows my clinical history better and he's always been better at planning for the future. AIBU of following his advice rather than the GPs?
