ANECDOTE

The Missed Case Of Sally's Fatigue

  • Sally is a 41-year-old who slept eight hours yet felt extreme daytime fatigue and needed naps to function.
  • Her doctor tested only TSH and T4 and told her thyroid was normal, which left her without answers until she sought further help.

  • T4 is relatively inactive and must convert to T3 to raise metabolism and energy.
  • This conversion happens in multiple tissues including liver, gut, adrenals, and requires nutrients and healthy detox pathways.

  • TSH is a brain (pituitary) hormone that signals the thyroid but doesn't measure thyroid hormone activity in tissues.
  • A normal TSH alone doesn't guarantee adequate T3 or proper thyroid function in the body.
