Thyroid problems – How do you know if you have thyroid problems


How do you know if you have thyroid problems

Symptoms of under-active thyroid include:

  • fluid retention
  • hair loss
  • yellow skin on the palms
  • sensitivity to heat or cold
  • fatigue
  • poor mental function
  • slowed heart rate
  • irregular periods
  • very dry skin
  • constipation
  • high cholesterol

What tests might you need?

  • If thyroid disease is suspected, blood tests should not be limited to TSH.
  • Other useful tests include thyroid antibodies, free T3, free T4 and reverse T3

Thyroid resistance syndrome (elevated reverse T3)

  • After some months on conventional thyroid treatment, T4 resistance can develop.
  • The syndrome occurs when T4 is not adequately converted to its active form: T3.
  • The conversion is easily disrupted, because it occurs in the liver, and requires many nutritional cofactors.
  • Instead of being converted to T3, a large amount of T4 is converted to reverse T3, which is inactive thyroid hormone.
  • The high level of reverse T3 causes symptoms of under-active thyroid, despite a normal blood test for TSH, T3 and T4.
  • Impaired conversion of T4 to T3 can also be caused by the elevation of the stress hormone cortisol.
  • Elevated reverse T3 can persist even once cortisol is normalised.
