Understanding the signs and symptoms of Hashimoto’s hypothyroidism

CONTRIBUTED CONTENT — Hypothyroidism, or low thyroid function, is a common diagnosis these days. However, did you know that an autoimmune disease called Hashimoto’s causes more than 90% of hypothyroidism cases? 

Hashimoto’s is an autoimmune disease, meaning the immune system attacks and destroys the thyroid gland, gradually worsening its function. However, most doctors won’t test you for Hashimoto’s because it doesn’t change how they treat you. The standard treatment is to prescribe thyroid hormone replacement medication. 

But at RedRiver Health and Wellness Center, we know that understanding the symptoms of Hashimoto’s, as well as which lab tests to order, can help you better manage your autoimmune condition.

Do you feel worse despite taking your thyroid medication?

One of the most common signs of Hashimoto’s is that you continue to have thyroid symptoms despite taking your thyroid medication. Your doctor may also need to continually increase your dose over time. This is because the autoimmune attacks against your thyroid gland are gradually destroying its function. 

Even though thyroid function is worsening, the medication produces normal thyroid lab results. In fact, you may not even notice if you accidentally skip a day of taking your meds because they are so ineffective in the face of ongoing autoimmune attacks. 

Do you swing back and forth between low and high thyroid symptoms?

Bouncing back and forth between low thyroid symptoms and high thyroid symptoms is another common sign of Hashimoto’s. One week you struggle with fatigue, headaches, constipation, depression and low libido. The next week you have insomnia, a racing heart, anxiety, tremors and feel manic.

This is because an autoimmune flare has damaged thyroid tissue, which spills excess thyroid hormone into the bloodstream. Some people are even misdiagnosed with bipolar disorder because of this.

During a period of low thyroid activity, a blood test will show high levels of thyroid-stimulating hormone. During a period of excess thyroid activity, your thyroid-stimulating hormone levels will be low.

Your thyroid-stimulating hormone levels may even be normal in between these periods. If you have your blood drawn during one of these “normal” periods, this can lead to a misdiagnosis and continued worsening of your thyroid function. This is why it’s important to test more often than once a year, such as quarterly.

Do you have other autoimmune diseases?

Autoimmune diseases are partly the result of an imbalanced immune system that is chronically inflamed. If this imbalance goes unmanaged, people often develop more than one autoimmune disease. 

This is because the hyper-zealous immune system becomes overly sensitive to body tissue and starts attacking it instead of protecting it. Which tissues it attacks depends on genetic predisposition and other factors.

Common secondary autoimmune diseases we see in our Hashimoto’s patients include pernicious anemia (an autoimmune disease that causes vitamin B12 deficiency), celiac disease and multiple sclerosis. In fact, multiple sclerosis, a neurological disease that compromises muscle function, is the most common secondary autoimmune disease in our patients – and a good reason to manage your Hashimoto’s! 

Symptoms of Hashimoto’s hypothyroidism

If you think you might have Hashimoto’s, see if any of these symptoms apply to you.

Low thyroid symptoms:

  • Always tired or sluggish.
  • Cold all the time; cold hands and feet.
  • Require excessive amounts of sleep to function well.
  • Weight gain despite low-calorie diet and exercise.
  • Gain weight very easily.
  • Constipation.
  • Depression and lack of motivation.
  • Morning headaches. 
  • Outer third of eyebrow thins.
  • Thinning of hair on scalp, face or genitals.
  • Hair loss.
  • Dry skin and scalp.
  • Mental sluggishness.
  • Brain fog.

High thyroid symptoms:

  • Heart palpitations.
  • Inward trembling.
  • Increased pulse rate, even at rest.
  • Feeling nervous and emotional.
  • Insomnia.
  • Night sweats.
  • Difficulty gaining weight.

Lab tests to identify Hashimoto’s

Symptoms are important, but a blood test provides proof of Hashimoto’s. These are lab markers you want to run:

  • Thyroid peroxidase antibodies (TPO Ab) – In most cases of Hashimoto’s, the immune system attacks thyroid peroxidase, an enzyme that activates thyroid hormone production.
  • Thyroglobulin antibodies (TGB Ab) – You should also test for antibodies to thyroxine-binding globulin, which the thyroid uses to produce thyroid hormones.
  • Thyroid-stimulating hormone antibodies (TSH Ab) – This test can identify Graves’ disease, an autoimmune disorder causing hyperthyroidism, although sometimes these antibodies are elevated in Hashimoto’s patients as well. This marker is often labeled as thyroid-stimulating immunoglobulin. 

If your autoimmune thyroid condition is advanced or if you react to bioidentical thyroid medication but not synthetic, you may also have antibodies to the thyroid hormones T4 and T3.

What if your test comes back negative?

Don’t despair if your test comes back negative even though you have all the symptoms of Hashimoto’s. The immune system constantly fluctuates, and lab values will too. You may have had your blood drawn during a time when the immune system was not flared up.

However, if your test is positive, this confirms Hashimoto’s hypothyroidism and that you urgently need to manage your autoimmune condition to avoid a worsening of health problems. 

Non-autoimmune causes of low thyroid function 

Although more than 90% of hypothyroidism cases in the U.S. are caused by Hashimoto’s, other metabolic factors can cause low thyroid function. 

One of the most common is poor conversion of thyroid hormones. The thyroid gland predominantly produces a form of thyroid hormone called T4. In order for the cells to use it, the body must convert it to T3, an active form of thyroid. This conversion happens primarily in the gut and the liver. Poor liver function, poor gut function, chronic stress and chronic inflammation are factors that prevent the conversion of T4 to T3, thus causing hypothyroid symptoms. 

We work with your prescribing physician for optimal results. Do not discontinue medication or hormone replacement therapy without consulting your prescribing physician. Visit our website to learn more about our services and schedule a free consultation.
