Hashimoto’s thyroiditis is the most common thyroid condition in the United States. In fact, it’s estimated that the majority of those with hypothyroidism actually have Hashimoto’s. Hashimoto’s – or Hashi’s – is an autoimmune condition that is ten times more likely to affect women than men. (1)
But what many Hashimoto’s patients may not understand is that they don’t have a problem with their thyroid as much as they have a problem with their immune system attacking their thyroid.
With an increase in autoimmune diseases and difficulty with diagnosing Hashimoto’s, also known as Autoimmune Hypothyroidism, it is important to understand what it is and how it can affect your life.
To better understand Hashimoto’s, and why it is a problem with the immune system and not the thyroid, we must first understand autoimmunity.
Rates of Autoimmune Disease
The frequency of autoimmune diseases has increased significantly over the past 30 years – this category of over 80 different diseases is now the number two cause of chronic illness and among the top ten causes of death for American women less than 65 years old. It is estimated that 50 million Americans now live with at least one autoimmune disease, and 75% of them are women. (1)
Sadly, having one autoimmune disease significantly increases the risk of receiving additional autoimmune diagnoses. (4)
What Causes Autoimmunity and Hashimoto’s
According to Alessio Fasano, researcher and MD, every autoimmune disease has 3 basic causes:
- Genetic Predisposition – autoimmunity does appear to run in families and some genetic links have been discovered
- Environmental Trigger(s) – stress, Western diet, nutrient deficiencies, food additives, toxins, GI infections and overgrowths (i.e., H.pylori, SIBO, Candida overgrowth), medications, etc.
- Leaky Gut – usually, this is the effect of chronic exposure to environmental triggers that damage the intestinal lining. This allows substances such as bacteria and undigested food proteins that should be eliminated from the body to be reabsorbed back into circulation. (7, 8, 9)
When all three of these factors are present and allowed to persist, the immune system goes into overdrive, wires can get crossed, and all of a sudden healthy body tissues can become the target of the attack by way of something called “molecular mimicry”.
Molecular Mimicry – how gluten (and other proteins) can trigger an attack on the thyroid
If the gut is leaky, gluten and other protein particles can leak through the intestinal walls. Since these proteins shouldn’t be present in that particular area of the body, they are viewed by the immune system as foreign invaders. The “troops” (Regulatory T cells and other immune cells) are signaled, and an attack is launched.
But parts of the gluten molecule (and certain other protein molecules) actually look similar to thyroid tissue and the immune system can confuse the two. The more often the immune system is called on to attack the gluten, the more likely this mix-up called “molecular mimicry” can occur, resulting in an attack on thyroid tissue instead.
This attack on healthy tissue is the start of autoimmunity.
What is Hashimoto’s Thyroiditis?
As you can see, at its root, Hashimoto’s is an immune dysfunction that results in thyroid dysfunction – it’s imperative that we maintain focus on that root issue of immune/autoimmune activity if we want Hashimoto’s naturally.
In Hashimoto’s, the primary tissue that is attacked and possibly eventually destroyed by the immune system is the thyroid, which compromises metabolism, heart rate, and body temperature regulation. Related tissues like the pituitary gland (which produces TSH) and thyroid receptor cells on tissues throughout the body (think of these as a lock on the door of the cells – when thyroid hormone arrives at the cell, it acts as a key which fits perfectly into the lock to open the “door” of the cell and allow the thyroid hormone to enter and begin its work) can also be damaged by Hashimoto’s.
Hashimoto’s causes hypothyroidism (hypo= low or below normal), where the thyroid can’t make enough thyroid hormone for the body’s needs. The thyroid is responsible for producing mostly inactive thyroid hormone (T4), along with small amounts of active thyroid hormone (T3). Inactive T4 is converted to active T3 primarily by the liver.
To make matters worse, the attack on the pituitary can reduce signals to the thyroid to make more hormone, and the attack of thyroid receptors can reduce the effects of activated T3, so that even the small amount of T3 that is produced can’t be used effectively.
How do I know if I have Hashimoto’s?
When the body can’t make enough of these hormones a variety of symptoms may occur. You may not even realize that some of the symptoms are caused by a disease, but they can have a huge impact on your life.
Symptoms of Hashimoto’s Thyroiditis:
- Weight gain
- Cold sensitivity
- Tingling in the hands and feet
- Hair loss or dry hair
- Difficulty concentrating or “brain fog”
- Muscle weakness and joint pain
- Puffy face
- Fertility issues
If you have these symptoms it is important to get checked for Hashimoto’s right away. The longer it goes unchecked, the more damage can occur to your thyroid and related tissues.
Left untreated, Hashimoto’s can lead to other health problems including an enlarged thyroid, heart problems, infertility, bone loss, and depression.
Lab Tests for Hashimoto’s Thyroiditis:
To better understand your thyroid function and to determine whether you have Hashimoto’s, your health care provider will should run a full thyroid panel including antibodies.
Unfortunately, it’s very common for just one or a few of these to be performed, which gives an incomplete picture of thyroid health and/or autoimmune function, risking missed or mistaken diagnoses.
- Thyroid-Stimulating Hormone (TSH) – Evaluates the pituitary’s ability to signal the thyroid to produce thyroid hormone
- Total Thyroxine (T4) – Measures he total amount of T4 (inactive thyroid hormone) produced by the thyroid gland
- Free Thyroxine (T4) – Measures the amount of T4 available to the cells and tissues
- Free Tri-iodothyronine (T3) – Measures the amount of T3 (active thyroid hormone) available to the cells and tissues once it has been converted from T4
- Reverse T3 – Measures the non-functioning form of the active hormone T3
- Thyroglobulin – Measures levels of the precursor to thyroid hormone that remains within the thyroid gland
- Thyroxine-Binding Globulin (TBG) – Measures levels of the protein that transports thyroid hormone through the blood.
- Antithyroglobulin antibody (Tg Ab) – Often measured along with TPO, these antibodies can attack proteins involved in the production of thyroid hormones rendering them dysfunctional
- Thyroid Peroxidase antibody (TPO Ab) – Often measured along with ATA, these antibodies can attack proteins involved in the production of thyroid hormones rendering them dysfunctional
A small percentage of individuals have Hashimoto’s but do not produce antibodies. In these or other cases where lab tests are inconclusive, a thyroid ultrasound may also be helpful to diagnose Hashimoto’s. (15)
Conventional Medical Treatment for Hashimoto’s
Synthetic Thyroid Hormone Medication
Western medicine routinely prescribes synthetic T4 thyroid hormone replacement (i.e., Synthroid, Levoxyl) for Hashimoto’s patients. For many, this is a necessary component of treatment. However, it’s important to remember that T4 medication has it’s limits.
3 Things Synthroid Can’t Do:
- Assist with conversion of T4 into active thyroid hormone (T3)
- Improve thyroid hormone binding and activity at receptor sites that may also be under attack
- Address the root issue of autoimmunity
Rarely, synthetic T3 medication (Cytomel, etc.) will be added to T4 – when needed, this can help significantly.
Thyroid Glandular Medications
Some medications (i.e., Armour Thyroid, Nature-Throid) are actually “glandulars”, medications derived from thyroid tissue of a pig or other animal. These are natural rather than synthetic and have both T4 and T3 together in the same pill. If synthetic medications haven’t worked well for you, these may be a good option to discuss with your provider.
Other Conventional Treatments
In advanced stages, radioactive iodine treatments or thyroid removal surgery are sometimes used. Unfortunately, even these drastic measures won’t fully resolve the condition because they don’t address the root issue of autoimmunity. (18)

5 Natural Ways to Live Well with Hashimoto’s
Remember, the ultimate aim when addressing Hashimoto’s and other autoimmune diseases holistically is to restore balance to the immune system to stop the autoimmune attack on the body. It’s unrealistic to expect an autoimmune condition to go away entirely, but it’s very possible to use diet, exercise, and other lifestyle modifications to snuff out autoimmune activity in the body. Many women with Hashimoto’s have achieved drastic reduction of thyroid antibodies and remission of their symptoms using this approach.
Here are five ways to naturally restore balance to your immune system and live well with Hashimoto’s.
1. Identify and correct nutrient deficiencies, and other toxicities
Consider working with myself or another holistic to test for nutrient deficiencies, and other toxicities that may be contributing to autoimmunity.
KEY NUTRIENTS FOR THYROID HEALTH
- Vitamin A
- Vitamin D
Note: Supplementation should be approached with caution as an excess of some nutrients can be harmful to your health. Speaking with a practitioner is advised before taking any supplements.
TOXINS THAT CAN HARM THE THYROID
- Glyphosate and other compounds in pesticides/herbicides
2. Go Gluten Free
Of all the foods that typical autoimmune diets like Autoimmune Protocol (AIP), GAPS Diet, Wahl’s Protocol, and others propose you cut out, gluten is the most definitively linked to increased attack on the thyroid, so it’s the top priority. Other foods like dairy and other grains are more likely to cross react with gluten, so it may be helpful for some people to remove these too, at least for a time, to calm down the level of autoimmunity, before deciding whether they can be reintroduced.
Other food sensitivities may be present, depending on the person, but improving gut health can often resolve or reduce these.
3. Fix Your Gut
Repairing a leaky gut (as well as other gut imbalances) will reduce immune triggers that perpetuate autoimmune attack. Comprehensive stool testing like the GI MAP + Zonulin holistic and functional medicine practitioners like Dena can order for you can be an extremely helpful step in identifying specific gut imbalances that need to be addressed to improve outcomes with Hashimoto’s Disease, and to help reduce the risk of developing additional autoimmune conditions. (4)
4. Reduce Stress
It is important to manage stress as chronic stress causes inflammation and impairs thyroid function at many different levels. (17) Try the following to manage stress and get your body back in balance:
- Work out – include cardiovascular, strengthening, and flexibility exercises. Remember, too much exercise can also be stressful to the body too!
- Get enough sleep – aim for 7 to 9 hours a night (learn how to sleep better naturally!)
- Relaxation techniques – prayer, meditation, deep breathing, etc.
5. Monitor your antibodies
Unfortunately, conventional medicine physicians usually don’t monitor thyroid antibodies after you’ve been diagnosed with Hashimoto’s, but they’re helpful since they measure the degree of autoimmune attack on your thyroid. Furthermore, antibody levels are very responsive to diet and lifestyle improvements, so can help you track which changes are most helpful for you.
- Thyroid Peroxidase Antibodies (TPO Ab)
- Thyroglobulin Antibodies (TG Ab)
