A member asked:
What could be the reason for a low t4 and low tsh on the bloodwork?
2 doctors weighed in across 2 answers
Many causes: There are many causes. Much depends on what exactly "low" means. One cause is "euthyroid sick syndrome". If you have other illnesses, including depression, the whole thyroid system tends to get lower. The solution is to treat the primary condition (eg depression). Other causes include pituitary disease, taking certain thyroid supplements (eg cytomel). Talk to your doctor.

How low?: If these were taken during a time that you were emotionally distraught, and they are not strikingly removed from the reference range (which is set so that several percent of healthies fall outside), your physician will repeat them when your life gets better. If way-low, pituitary disease is a concern.
