Thy­roid Replacement


Many people have symptoms of an under­ac­tive thyroid but are told that there is no problem with their thyroid because their TSH (thyroid stim­u­lat­ing hormone) testing levels are “normal”

A TSH test is a lab test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood. It is the most common screening test for thyroid disease.

When the thyroid gland is under­ac­tive, the metab­o­lism slows down and you may suf­fer from symptoms such as:

  • Fatigue
  • Weight gain
  • Con­sti­pa­tion
  • Dry skin
  • Brittle nails or Hair loss
  • Cold intolerance/cold hands and feet
  • Men­strual irregularities
  • Headaches/migraines
  • Decreased memory and dif­fi­cult concentrating
  • Swollen legs, feet, hands, abdomen and face
Thy­roid Replacement

It is important to have blood tests that pro­vide a full thyroid panel which includes a mea­sure­ment of Free T4, Free T3 (the active form of thyroid hormone), thyroid anti­bod­ies and reverse T3 (which is an inactive form of thyroid hormone). All these mea­sure­ment are nec­es­sary to review prior to choosing appro­pri­ate treatment.

Inad­e­quate thyroid production may be caused by nutrient defi­cien­cies, autoimmune thyroid disease, liver disease and adrenal fatigue.

Many family physicians and endocri­nol­o­gists prescribe synthetic T4 (Syn­throid) for their hypothy­roid patients. This may adequately treat some patients. However this approach is not suf­fi­cient for patients who have dif­fi­cult con­vert­ing T4 to T3 or have a high level of inactive T3.

Most patients feel better when both T4 and T3 are replaced.

When one has low T3 levels, which are typ­i­cal with synthetic hormone use such as Syn­throid, the brain does not work properly. It is important to use a prepa­ra­tion with T3 in it because T3 does 90% of the work of the thyroid in the body. So one should use a com­bi­na­tion of T4 and T3‚ which com­pen­sates for the inability to con­vert T4 to T3.

Armour thyroid is des­ic­cated thyroid and has both T3 and T4.

It is also nec­es­sary to pro­vide sup­ple­ments which help the thyroid function optimally, such as iodine, selenium and zinc. Some people improve using only an adrenal/thyroid sup­ple­ment. Others need thyroid hormone tem­porar­ily, while others need longer-term thyroid replacement.
