Thyroid labs-help!

[Javableue]

Can anyone help me interpret my labs? I've been feeling extremely fatigued over the last week or so with tachycardia when I have to stand, feel very weak. I have a multinodular diffuse goitre that I've had for at least 5 years.

Javableue,

Thyroid antibodies are negative for autoimmune thyroid disease (Hashimoto's).

TSH is low-normal, FT4 is low in range, but FT3 5.0 is relatively good.

Ferritin is optimal >100 so you could supplement iron to see whether fatigue and tachycardia improve. Take each iron tablet with 500-1,000mg vitamin C to aid absorption and minimise constipation. Take iron 4 hours away from Levothyroxine.

B12 >500 is unlikely to be deficient and folate is good.

Thank you for your advice Clutter! That's so helpful. I will think about doing some more iron labs and then maybe consider supplementation.
