TL;DR
How thyroid hormones influence fatigue, weight, and mood, and why TSH alone is sometimes insufficient.
Thyroid basics
Thyroid hormones regulate metabolic rate, temperature tolerance, bowel habits, hair and skin changes, and energy. Hypothyroid patterns can mimic depression or burnout.
TSH screening catches many cases, but some patients with persistent symptoms need free T4, free T3, and antibody testing based on clinical judgment.
Overlap with other pillars
Thyroid dysfunction overlaps with iron deficiency, sleep disorders, and cortisol dysregulation. A fatigue workup often spans hormone and energy pathways together.
Only a licensed clinician should interpret thyroid results and prescribe treatment.
Next steps
If fatigue and hormone symptoms cluster, begin with a structured optimization analysis and comprehensive labs rather than isolated supplements.
General education only. Abnormal symptoms warrant professional evaluation.
