Under-active thyroid function is becoming more and more common and even today it is horribly under-diagnosed. The good news is that once it is diagnosed, it can be very easy to treat, and therapy can alleviate your symptoms and make life worth living again! The thyroid gland is in charge of regulating the body's metabolic rate. If the thyroid gland is sluggish or can’t produce sufficient amounts of thyroid hormones, the metabolism decreases, fatigue sets in and the person gains weight. A simple blood test asking for specific thyroid tests can help determine if you could benefit from thyroid hormone optimization.

Underactive Thyroid Signs and Symptoms include:

  • Fatigue
  • Constipation
  • Weight gain
  • Menstrual irregularities
  • Feeling depressed / anxious
  • Poor concentration
  • Cold intolerance / low body temperature
  • Rough dry skin
  • Headaches
  • Low libido
  • Brittle nails
  • Thinning hair
  • Water retention / edema
  • Infertility
  • Muscle weakness
  • Increased appetite

two primary THYROID hormones

Thyroxin (T4)

T4 is the storage form of thyroid hormone. The body uses it to make triiodothyronine (T3), the active form of thyroid hormone. Most synthetic thyroid medications, such as Synthroid and Levothyroxine, are pure T4 only. These synthetics are fine if your body has the ability to properly convert them into T3. Unfortunately, many people find out that their bodies have a hard converting T4 to T3. This could be due to nutrient deficiencies, certain medication, or lack of the enzyme that helps in the conversion process.

Triiodothyronine (T3)

T3 is the active form of thyroid hormone. This is the thyroid hormone that does most of the work and affects most of the body systems that depend on thyroid hormone.

Common causes of an underactive thyroid

Hypothalamic dysfunction 

Your thyroid gland may be fine but it is not getting adequate stimulation from the hypothalamus and is basically "asleep." In this situation, simply taking a mix of T4 and T3 at the dose that feels best may be adequate. As the hypothalamic function recovers, you may often be able to wean off the thyroid hormone.

Hashimoto's Thyroiditis

In this autoimmune process your body's immune system attacks and damages the thyroid. This can be diagnosed by a blood test called an "anti-TPO antibody." If the anti-TPO antibody is elevated, you likely have Hashimoto's Thyroiditis and may need to take thyroid supplementation for the rest of your life.

Inadequate conversion of the T4 thyroid hormone to active T3

In this situation, which is very common in fibromyalgia, patients often respond best to therapy with pure T3 hormone. Blood tests are normal despite needing 9-27 mcg a day of T3 thyroid hormone.

Receptor resistance

In this situation, your body is making adequate amounts of thyroid hormone but the areas that they stimulate are very slow to recognize the thyroid hormones' presence. Because of this, it takes a very high level of pure T3 hormone to get a normal response. This problem often resolves over one to two years on the high-dose T3 therapy.
