Fatigue. Feeling cold. Brain fog. Weight changes.
And yet, TSH and T4 are within range.
One piece worth considering is chronic inflammation. It can interfere with the conversion of T4 into T3, the active thyroid hormone your cells actually use.
This doesn’t mean every case of fatigue is a thyroid problem. It means one lab result may not always tell the whole story.
👉 If symptoms continue, track your energy, sleep, digestion, and cold tolerance for a few days and bring that information to your next appointment.
Your body’s signals are information too.
