WHAT IT MEASURES
TSH tells your thyroid how much hormone to make. When the thyroid is sluggish, TSH rises to push it harder.
WHY IT MATTERS
Your thyroid sets your metabolic pace. Small shifts affect energy, weight, mood and temperature.
WHEN TO RETEST
Yearly, or sooner if you notice changes in energy or weight.
WHAT MOVES IT
Five levers, ranked.
Based on clinical evidence. Your clinician picks the ones that fit you.
Enough iodine
Dairy, eggs and iodised salt.
Selenium foods
Two Brazil nuts a day is plenty.
Manage stress
Chronic stress can shift TSH.
Check medications
Some supplements skew the result.
Treatment, if needed
Your clinician will discuss options.
