I’ve been on T replacement for 5.5 years. Have felt like I’ve had low thyroid symptoms for a few years now. Weight gain, fatigue, dry skin on my body, oily skin on my face (may be T related), thinning of the outer edges of my eyebrows, bloating/puffiness. My free T4 hasn’t changed in 3 years according to old bloodwork and my free T3 is within 0.05 pg/mL of where it was 3 years ago. That time interval was within when I felt kinda hypo.
I got thyroid labs done and am waiting on updated Testosterone, Free T, and estradiol numbers. I’m a little concerned by the Free T4 number below as it’s on the lower end of the scale, while my Free T3 and TSH look just fine. I have an appointment with an endocrinologist next week and am curious if a) these numbers look at all unusual to you guys who know this stuff b) point to anything specific I should ask the endo about.
