This episdoe explores the connection between mental health and thyroid autoimmunity, and why symptoms like anxiety, low mood, or brain fog are often biologically influenced, not just emotional. I walk through how thyroid hormone imbalances, inflammation, and nervous system regulation can affect mental well-being, including the role of the gut. If you would prefer to listen to the interview you can access it by Clicking Here.
Mental health challenges are often an overlooked part of thyroid and autoimmune disease and that matters more than most people realize.
A lot of people with thyroid and autoimmune thyroid conditions experience symptoms such as anxiety; depression; irritability; for those with Graves’, there is something called Graves’ rage, which I have a past podcast on this topic; brain fog.
What’s important to understand is these are not just emotional symptoms. Anxiety, depression, Graves’ rage, these are often biologically driven.
I had on the podcast a few years ago Dr. Aimie Apigian, who has a book now called The Biology of Trauma that was recently released as a podcast. The episode she was on on my podcast focused on the biology of trauma, but she has her own podcast where she talks about the biology of trauma. It’s also one of her programs.
Again, the goal is not just about the emotions. Biology definitely plays a role. This of course is a podcast that focuses on helping people with thyroid and autoimmune thyroid conditions. There are other factors here.
That being said, I want to start by talking about the impact of thyroid hormone imbalances. We have the main thyroid hormones, T4 and T3. There is also T1 and T2, which we’re still learning about. The thyroid gland produces mostly T4 and a little bit of T3. What happens is T4 converts into T3, and T3 is the active form of thyroid hormone. This influences most tissues in the body as well as the neurotransmitters, such as serotonin, dopamine, GABA.
When we think of neurotransmitters, a lot of people think about the brain, but they’re not thinking about other factors that influence these neurotransmitters, including the gut. We’ll talk about the role of the gut later on because you do need a healthy gut to have healthy neurotransmitters. Arguably, you also need healthy thyroid hormones to have healthy neurotransmitters. If you have imbalances in thyroid hormones, they will affect neurotransmitters in different ways.
If someone has hyperthyroidism, including Graves’, they’re more likely to experience anxiety with elevation of thyroid hormone. Doesn’t mean that you can’t experience depression if you have hyperthyroidism. Anxiety is certainly more common.
Some people have anxiety prior to their hyperthyroid diagnosis, so it’s not always the hyperthyroidism. Sometimes, hyperthyroidism is exacerbating the anxiety. I have seen that in quite a number of patients, where they had anxiety for many years. They were diagnosed with hyperthyroidism, many times Graves’, but it could also be a different hyperthyroid condition, and their anxiety worsened. Sometimes, the person never had anxiety until they were diagnosed with hyperthyroidism.
There is a biological factor behind this anxiety. It’s not just emotional. Many doctors will dismiss this.
Depression, more common in low thyroid, hypothyroid states. People with hypothyroidism can experience anxiety, too. People with hyperthyroidism can definitely experience depression.
Like I said, we also need to consider the conversion. If someone has a problem converting T4 into T3, T4 might look good on a blood test as well as TSH. The person might have low T3 levels, and that could be a factor in causing some of these symptoms, usually more likely depression. Like I said, it’s not like someone with hypothyroidism can’t experience anxiety. Same thing with hyperthyroid folks experiencing depression.
I want to talk about the autoimmune component. It’s not just about the thyroid hormone imbalance. When you deal with autoimmunity, you have increasing proinflammatory cytokines. It’s a proinflammatory state. This inflammation can affect the brain. Not everybody with Graves’ and Hashimoto’s will have neuroinflammation, brain inflammation, but that definitely is a factor to consider.
There are certain markers that you can test for. Obviously, you can test for thyroid hormones. You could test for cytokines. There are companies that test for cytokines. I can’t say I do that.
Many years ago, there was a book by Dr. Datis Kharazzian, Why Do I Still Have Thyroid Symptoms?, from 2010. He was the first one I know of who spoke about cytokines. They were more popular back then, as far as the testing.
I don’t see a lot of functional medicine practitioners test for cytokines these days. Not to say none of them don’t. I’m sure some do. Back then, 10-15 years ago, it was more common. They’re expensive. I can’t say they give a lot of useful information. Some of the markers can be valuable maybe. The point is, you could test for cytokines if you really wanted to.
Talking about neuroinflammation, there is a marker called quinolinic acid, which you can test for on an organic acids test. Also, the DUTCH test has a little section that looks at organic acids. Not as comprehensive as companies like Mosaic Diagnostics or Genovva. They have more comprehensive organic acids tests. The DUTCH test has a little organic acids section, and they look at quinolinic acid.
If this marker is elevated, that means you very well might have brain inflammation. It’s not telling you what the cause of the inflammation is, but still, it could be helpful. If you have neuroinflammation, you probably want to know it.
You might have heard me talk about the triad of autoimmunity. There are three components necessary for autoimmunity to develop. One is a genetic predisposition. Two is an exposure to one or more environmental triggers. Three is an increase in intestinal permeability.
I am bringing this up because if you have that increase in intestinal permeability, which is a medical term for a leaky gut, there is a decent chance you have increased permeability in the blood-brain barrier. If you have a leaky gut, you might also have a leaky brain.
You could also test for this, too. Rx Labs is one company that offers a test. They have different arrays. It’s Array #20, which is their blood-brain permeability test. I can’t say this is something I commonly test for. Just like cytokines, which I also don’t test for. You could test for a leaky brain though.
That is the relationship between the thyroid and mental health symptoms. Again, having that inflammation, especially neuroinflammation, can also lead to anxiety, depression.
The point is you want to balance the thyroid hormones. You probably want to do more than that. If someone has hyperthyroidism, you want to lower those hormones, whether it’s through antithyroid medication such as methimazole or PTU; or a natural approach, like I took the herb bugleweed. I also took motherwort, but that was more for symptoms; that doesn’t affect thyroid hormones. L-carnitine in higher doses can also block the entry of thyroid hormone into the cell, so that is also an option to consider. Lithium orotate.
If someone has low thyroid hormones, there is a time and place for thyroid hormone replacement to increase the thyroid hormones.
Most people with thyroid hormone issues also have an autoimmune component. Most people with hyperthyroidism have Graves’. Most people with hypothyroidism have Hashimoto’s. If someone has anxiety, depression, brain fog, in addition to balancing the thyroid hormones, you want to address the autoimmune component, reduce the inflammation. If someone has neuroinflammation, you want to reduce that as well.
When it comes to leaky gut versus leaky brain, I’m pretty sure I’ve had some practitioners on the podcast who have spoken about this. A lot of the factors that help heal the gut will also heal the brain. I have spoken a lot in other podcast episodes about gut health and leaky gut.
I want to talk a little bit about adrenals and trauma. Chronic stress affects what’s called the HPA axis, which is the hypothalamic pituitary adrenal axis. It causes HPA axis dysregulation. This can also sometimes lead to some mental health symptoms.
Keep in mind that there is not only the HPA axis, but the HPT axis, the hypothalamic pituitary thyroid axis. Chronic stress affects the adrenals and also has an impact on the thyroid.
Then there is trauma. Trauma is pretty common. Getting back to what I said earlier, emotional trauma can have physiological consequences. It’s not uncommon to have the onset of Graves’ or Hashimoto’s or the antibodies for both, because a lot of people do have antibodies for both, after major life events, after major stressors, traumas.
Without question, chronic stress was a big factor in my Graves’ condition, which I’ve mentioned in previous episodes. I don’t think trauma was a big factor in the development of my Graves’ condition. The truth is, sometimes, we don’t know. I was in denial about stress. I knew chronic stress was a factor, but I thought I did a good job of handling it.
Sometimes, there are traumas that we remember, but there are traumas that we might not remember. There might be some traumas that I don’t remember, and sometimes, the smaller traumas might affect us in ways that we don’t think.
When we think about traumas, sometimes we think about sexual abuse or physical abuse. Again, it doesn’t have to be this. Everybody’s perception of trauma is different.
I should mention I didn’t think I experienced anxiety or depression when I dealt with Graves’ back in 2008/2009. It doesn’t mean my mental health was in a perfect state. I definitely don’t think it was.
I wouldn’t say I was depressed, but I was pretty despondent when I learned that I had Graves’. I think it was even before then, when I learned I had hyperthyroidism. I suspected I had Graves’ before testing, which knowing what I know now, I should have tested on my own. I played a waiting game and saw an endocrinologist. Back then, I didn’t have the experience I have now. I was a practicing chiropractor and was not doing what I do now. I was relying on the so-called experts.
I wouldn’t say my mental health was in a great state back then. I don’t recall having any anxiety or true depression.
Getting back to trauma. The thing with trauma, when we talk about chronic stress affecting the HPA axis, which is bad enough, causing the HPA axis dysregulation, chronic stress and trauma can also in some cases lead to nervous system dysregulation.
The nervous system controls every cell and tissue of the body. This is something we learned in chiropractic school. Chiropractors are perceived as being back and neck pain doctors, but we are actually nervous system doctors. That is our main focus, at least when I was in chiropractic school. We were taught about balancing the nervous system, not addressing neck and back pain. We addressed neck and back pain by balancing the nervous system.
The nervous system controls the thyroid gland. It controls the gut. You really do need to have a healthy nervous system to have a healthy body. Knowing that, you can understand how trauma can have dire consequences on your entire body and potentially lead to a chronic health condition such as Graves’ or Hashimoto’s.
Now, I want to talk a little bit more about the gut. I mentioned earlier that a healthy gut is important for healthy neurotransmitters. Most of the neurotransmitters are actually produced in the gut. More than 90% of serotonin is produced in the gut.
If you have a lot of dysbiosis, which is an imbalance, specifically gut dysbiosis, that could cause imbalances of neurotransmitters, which can lead to symptoms such as anxiety, depression, brain fog. Having an unhealthy gut can also affect mental health.
This isn’t just me saying this. This is based on research. There is also functional medicine psychiatrist Dr. Kelly Brogan, who has written a few books, including one called A Mind of Your Own. She talks about the impact of gut on depression and anxiety. I highly recommend reading her book. I’m pretty sure I listened to it on Audible. Either way, reading, listening. She also has an article on her website, “Depression Starts in Your Gut.”
Healthy thyroid, healthy immune system, healthy nervous system, healthy gut. The nervous system and gut have that relationship because you have the vagus nerve. Everything is connected. I’ll talk more about vagus nerve exercises later.
Sticking with gut issues that could potentially- First of all, gut issues play a role in autoimmunity, but they could also play a role in imbalances of neurotransmitters.
SIBO is one. This is too much bacteria in the small intestine. You could do a test. There is breath testing. Some people like to do regular testing. Some people don’t like to do testing. I like testing, even though it’s not perfect. If someone has it, it’s nice to see it and potentially retest. SIBO can definitely be a factor in increasing permeability of the gut.
H-pylori is a potential trigger of thyroid autoimmunity.
Candida overgrowth. Candida is a type of yeast. Yeast is normal in the gut. We are not trying to completely get rid of the yeast. We just want to address the overgrowth.
I mentioned a leaky gut. These things—SIBO, H-pylori, candida, parasites—can all cause that leaky gut. We spoke about the impact of leaky gut. If you have a leaky gut, there is a good chance you have a leaky brain, especially if you have these mental health symptoms. It could also be related to the imbalance of thyroid hormone. It doesn’t mean you necessarily have a leaky brain, but something to consider.
I also want to talk about nutrient deficiencies. They can affect mood. Nutrients are important for optimal thyroid health. We know we need healthy levels of iron. Iodine is controversial, but you still need healthy iodine for healthy thyroid hormones. Zinc as well.
You need optimal gut health for optimal digestion and absorption of nutrients. If you have an increased toxic burden, which most of us have, that will use more nutrients. Detoxification is nutrient dependent. Mitochondria, which are the energy powerhouses of the cells, are nutrient dependent. We can’t overlook the importance of nutrients.
If you’re deficient in nutrients, that can lead to symptoms. Iron, zinc, magnesium, selenium, some of the B vitamins (B12 and folate, B6). A lot of different factors.
Thyroid health definitely is important, but it goes beyond the thyroid.
We are not done yet. There are also medications. Medications can play a role in the development of mental health symptoms. For those with hyperthyroidism, a lot of people take antithyroid medication. Time and place for antithyroid meds.
Beta blockers, too. Some take beta blockers. Some beta blockers, like propranolol, affect the conversion of T4 to T3. They inhibit that conversion. They’re lowering thyroid hormones, which is what you want. If it’s too high, that can cause anxiety. Some people will take too high of a dose, and they will be hypo for a while. They might experience other symptoms related to low thyroid hormones.
Same thing if someone has hypothyroidism, and they are on thyroid hormone replacement, whether it’s levothyroxine or desiccated thyroid. If they are taking too much, it could cause anxiety or hyper symptoms and lead to anxiety.
Of course, there are medications to treat some of these symptoms, like anxiety. Like I said, it’s not just symptoms. You don’t want to mask the symptoms. You want to address the cause of the problem. There is a time and place for antidepressants and medications for anxiety, but these are not addressing the thyroid hormone imbalance or neuroinflammation or gut imbalances or nutrient deficiencies or regulating the nervous system. Time and place for medications, but you always want to address the cause of the problem.
When someone works with me, and they’re taking either antithyroid medication or thyroid hormone replacement, that’s fine if they want to do that. A lot of my patients do. If they are tolerating the meds, where side effects are common, I’m okay with that because you want to be safe while addressing the cause of the problem.
As we wrap this up, let’s go ahead and summarize what we spoke about. When it comes to thyroid hormones, you want to balance the thyroid hormone levels safely. Some people will take antithyroid meds or bugleweed. If you have hypothyroidism, maybe it’s thyroid hormone replacement or glandulars. If you have Graves’ or Hashimoto’s or antibodies for both, you want to address the autoimmune component as well.
Gut health is important. A lot of people have gut issues even if they don’t have symptoms.
I spoke about adrenal support and regulating the nervous system for those who have dysregulation there. You might want to start with blocking out time for stress management, starting with five minutes a day. Get into a routine of stress handling.
You might need to go beyond that. You might need to do some vagus nerve exercises such as humming, singing out loud, vigorous gargling, coldness, whether it’s cold showers like I take. Some people do cold plunges. I mentioned nervous system retraining in some cases.
Addressing nutrient deficiencies.
You might need to work with someone such as a counselor or psychologist who focuses on trauma, such as Dr. Aimie. Maybe even join a program such as Primal Trust or the Gupta Method. It depends.
If it’s related to the thyroid hormone imbalance and autoimmunity, working with someone like me or someone else who focuses on Graves’ or Hashimoto’s might be all that you need. If it’s more of a trauma problem, where you need nervous system retraining, to some extent, I help people with that, but there are definitely people who focus more on that all the time with their patients and clients.
Final takeaways. You don’t want to dismiss anxiety or depression as just stress. It’s not just stress or emotional symptoms. There is a physiological basis often.
Always look at gut health, especially if the mental health symptoms persist. I always give gut support. I can’t say I do comprehensive gut testing on every single person. I do a lot of GI Maps. I have done SIBO testing. I have done organic acids testing, which looks at yeast and Clostridia. It doesn’t mean everybody needs to spend thousands of dollars on testing. Some people do need to do more comprehensive testing than others. Don’t overlook gut health.
Of course, the basics. Prioritize sleep, blood sugar stability. Address nutrients. If necessary, seek help for trauma. Maybe look into nervous system retraining.
When it comes to thyroid hormone imbalances and the autoimmune component, work with a practitioner who understands thyroid autoimmunity.
I think that’s it. We covered a lot. It’s something that I haven’t spoken about enough on the podcast. I have had some experts talk about anxiety and depression, so it’s not like it hasn’t been covered. Really wanted to do a solo episode to tie everything together.
Hope you found this episode to be valuable. Appreciate you taking the time to listen to this. I’ll wrap it up and look forward to catching you in the next episode.
