Functional Medicine Toronto Therapies: How Targeting Thyroid Issues Could Lessen Depression


Did you know that you could treat thyroid issues with functional medicine from Toronto? In fact, thyroid treatments might even assist in improving mental health. We explained how the thyroid’s role is to secrete hormones into the bloodstream. These hormones have a wide range of jobs to fulfill, such as regulating metabolism, influencing brain development, optimizing fertility, and other bodily functions.

But when your thyroid becomes compromised – by releasing not enough or excessive amounts of hormones – this could trigger an unbalance in the body, setting off unwanted individual symptoms like memory issues, unexplained weight gain or weight loss, infertility and excessive fatigue. As discussed in our previous blog post, toxins affect your thyroid health as well, and how functional medicine may help.

Now what’s astonishing is that thyroid health is connected to mental health! According to the Thyroid Foundation of Canada, “depression may be the first sign of an overactive or underactive thyroid.” Unfortunately, some healthcare providers attempt to tackle the depressive state first without considering the thyroid.

So what’s the link between your thyroid and depression? Here, we briefly explain thyroid functions, how your thyroid affects mental health, and how to visit the Toronto Functional Medicine for clinical care.

Understanding Thyroid Health: The Functional Medicine Approach

The thyroid is a butterfly-shaped gland. Though small in size, it provides several functions!

There is a hormone called TSH (thyroid stimulating hormone) that helps to release two thyroid-related hormones: triiodothyronine (T3) and thyroxine (T4). When they work together, T3 and T4 help with regulating your heart function, metabolism, body temperature, and additional bodily functions. The thyroid hormones work like this in the body:

  • The hypothalamus secretes TRH (thyroid-releasing hormone).
  • Then it stimulates the thyroid-stimulating hormone (TSH) to be secreted by the pituitary gland.
  • As a result, T3 and T4 are created in the thyroid and then released into the blood.

This process operates like a “loop”. When these thyroid hormones increase, TRH and TSH secretions come to a halt. But when there’s a reduction in T3 and T4, this process “loops” around again. If your hypothalamus, thyroid and pituitary gland are compromised you could have an unequal amount of T4 and T3. Accordingly, weakness, sleep issues, unexplained weight loss or weight gain, or even the onset of chronic conditions could be triggered.

Knowing that now, what is the connection between depression and thyroid health?

What Depression Has Got to Do With Your Thyroid

A paper from the Journal of Thyroid Research explains, “Patients with thyroid disorders are more prone to develop depressive symptoms and conversely depression may be accompanied by various subtle thyroid abnormalities.”

Those with depression tend to have faulty hypothalamic-pituitary-thyroid (HPT) and hypothalamic-pituitary-adrenal (HPA) axes. (The HPT and HPA are two axes that regulate pathways for thyroid hormones.) One study noted that outpatients with major depression had marginally excessive TSH levels.

When treating depression, consider opting for patient-centered care that reflects on both your emotions and the state of your body systems. That said, a functional medicine practitioner should analyze thyroid-related lab tests, as depression could be a symptom of hyper- or hypothyroidism.

At the Toronto Functional Medicine Centre, our healthcare providers would consider your individuality (lifestyle factors, environmental factors, genetics, nutritional deficiencies, etc.) and physiology to address depression. Functional medicine lab tests are part of our evidence-based approach to wellness, so we would suggest a thyroid panel to see if thyroid hormones are wonky. Based on these lab tests, we could build a comprehensive treatment plan to target both thyroid and depression with Western medicine or natural treatments.

Are you suffering from high stress levels, anxiety, and depression? The Toronto Functional Medicine Centre can support you with patient-centered care.  Our functional medicine approaches in treatment could provide you with chronic pain relief, an energy boost, improved sleep quality, and a fresh outlook on life.
