Thyroid Problems Becoming More Common: 3 Blood Tests to Take

Thyroid Tests

There is no reason for people with thyroid imbalance to go undiagnosed.

There’s a lot of concern about thyroid health. There should be! It’s a problem that’s getting worse.

Doctors used to think that for every eight low thyroid cases, one was of overactive thyroid (hyperthyroidism), and the other seven were of underactive thyroid (hypothyroidism).

That’s changed. Now, general practitioners see one hyperthyroid case in about every four hypothyroid cases. And, hypothyroidism is becoming more common. The same goes for autoimmune thyroid disease.

When I first started practicing about thirty years ago, autoimmune thyroid disease like Hashimoto’s Thyroiditis was uncommon. Now this condition is not only more common, but more complicated, and there’s a gender difference: it’s 15-20 times more common in women than in men.

The Beginnings of Thyroid Treatment

One of my first mentors in bio-identical hormone replacement therapy was Dr. Thierry Hertoghe from Belgium. We spent time together in the mid-1990s in San Diego and I later visited his clinic in Brussels. One of the many things that made Dr. Hertoghe a leader in hormone therapy was his family background. His lineage spans more than four generations of endocrinologists, including his great-grandfather who was the first doctor in Europe to give patients thyroid hormone.

At that time, desiccated pig thyroid gland preparations were used. It was not until 1958 that the first synthetic levothyroxine tablets were marketed in the US.

I saw the original photos of patients before diagnosis and after three months of treatment. A thirty-year-old man with a few strands of thin white hair, dropping facial muscles, puffy eyes, and a blank stare was transformed into a young man with thick dark hair, erect posture, and a clear gaze. The results were so dramatic, patients and doctors believed it was like a miracle.

We’ve learned a lot about the thyroid gland since the time of Dr. Hertoghe’s great-grandfather. Doctors and patients now regularly perform blood tests to evaluate thyroid health.

In our times, there is no reason for people with thyroid disease to go undiagnosed.

What Tests to Take?

Because thyroid gland disease and hormone imbalance has become so common, I routinely screen all new patients using three basic blood tests. You no longer need a doctor to check your thyroid health markers, though. You can order your own blood tests through online personal lab testing services.

To see if your thyroid is functioning correctly, order these three tests: Thyroid-stimulating Hormone (TSH), Free Thyroxine (free T4), and Free Triiodothyronine (free T3).

I find these three tests more useful for my patients than the standard thyroid panel that includes T3 uptake and total T4, because results are relatively easy to interpret.

If your TSH is high, your thyroid gland is under functioning. TSH is a hormone made in the pituitary gland, which regulates the function of the thyroid gland. When the body needs more thyroid hormone, the pituitary secrets TSH, which signals the thyroid gland to increase hormone production.

A low TSH level means your thyroid gland is on overdrive, so the pituitary gland doesn’t need to secrete TSH. Low TSH suggests hyperthyroidism.

If you are not on thyroid hormone replacement therapy, results within the desirable range suggest a normal functioning thyroid gland. However, if you have hypothyroidism and are taking thyroid hormone replacement, you may not feel well until your TSH is in the optimal range level.

The same goes for Free Thyroxine and Free Triiodothyronine. To feel well and more energetic, you may need to achieve FT4 and FT3 levels in the upper limits of the normal range

Your FT4 is the form of thyroxine that circulates in the blood unattached—“free” or unbound to proteins that help shuttle hormones around the body. Too much is associated with hyperthyroidism. Too little means an underactive thyroid and is associated with metabolic syndrome.

Free T3 is a form of bioavailable thyroid hormone and the most metabolically active of thyroid hormones. Too little is associated with hypothyroidism and too much with hyperthyroidism. Some thyroid experts call FT3 the metabolic throttle that fuels cellular function. Low levels are also associated with coronary artery disease and other states of chronic inflammation in the body.

Symptoms of Thyroid Problems

Severe chronic fatigue is the main symptom linked to an under functioning thyroid gland. But there are many other symptoms, including dry rough skin and hair loss, that make up the complete symptom picture of hypothyroidism.

Top 10 Symptoms of Hypothyroidism

  1. Dry, coarse skin
  2. Fatigue and lethargy
  3. Slow thinking
  4. Depression
  5. Reduced heart rate
  6. Increased sensitivity to cold
  7. Tingling or numbness in the hands
  8. Goiter (an enlargement of the thyroid gland in your neck)
  9. Constipation
  10. Heavy menstrual periods

Top 10 Symptoms of Hyperthyroidism

  1. Fatigue and weakness
  2. Rapid heartbeat
  3. Feeling shaky, overly nervous
  4. Weight loss
  5. Increased appetite
  6. Diarrhea
  7. Thin skin
  8. Intolerance to heat and excessive sweating
  9. Goiter
  10. Bulging of the eyes

If you have any of these symptoms, get tested for TSH, FT4, and FT3. If you find abnormal results, see your doctor or endocrinologist for an assessment and to figure out if other tests are necessary.

What’s Causing It?

Hypothyroidism is a relatively common condition. Hyperthyroidism and autoimmune forms of thyroid disease are becoming more common than ever before. We don’t know all the reasons for rising thyroid gland imbalance, but stress, indoor air pollution, chemicals in our water and food supply, and modern diet—including iodine deficiency—are just some of the potential causes.

Increased levels of radiation exposure, including overuse of dental x-rays, and long-term exposure to bisphenol-A (BPA) found in plastic water bottles are two other potential triggers.

One common thread in the mystery is inflammation. Thyroiditis (inflammation of the thyroid) is a known medical condition. Hashimoto’s thyroiditis is an example of a type of autoimmune hypothyroidism.

Chronic, low-grade inflammation may have a role in other forms of thyroid disease as well. For example, gluten and gliadin associated with allergy to wheat are known to trigger inflammation. If you have celiac disease, you are four times more likely to develop an autoimmune thyroid condition.

Some experts claim we are in the midst of an epidemic of undiagnosed thyroid disease. All the statistics are not in yet, but from a clinical perspective, doctors are seeing more thyroid cases than before. One thing we do know is that all autoimmune diseases are becoming more common, including autoimmune thyroid conditions.

Given that all types of thyroid diseases have become common, including thyroid cancer, it’s wise to consider testing your thyroid gland.
