Thyroid
Thyroid Stimulating Hormone (TSH)
TSH isn’t a thyroid hormone—it’s the control signal from your brain telling your thyroid to make more T3 and T4. Higher TSH usually means your brain is yelling at the thyroid to work harder. Lower TSH means your brain thinks the thyroid is doing fine or even overproducing.
