Do These Symptoms Sound Familiar?

Feeling tired all the time isn’t the only sign of hypothyroidism or Hashimoto’s thyroiditis. Patients often come to our clinic with symptoms such as:

• Fatigue or low energy
• Brain fog or poor concentration
• Weight gain or difficulty losing weight
• Feeling cold more often than others

• Constipation

If these symptoms sound familiar, a comprehensive assessment can help determine whether your thyroid, or another underlying health concern, is contributing to how you feel.

Our Approach to Thyroid Treatment

Dr. Matt Gowan, ND has prescribing rights in Ontario and can prescribe desiccated thyroid hormone when appropriate. However, medication is not always the first step.

Thyroid care at our clinic focuses on identifying underlying factors rather than simply treating lab numbers.

Treatment may include:

• Comprehensive thyroid testing to better understand thyroid function and contributing factors

• Nutrition strategies to support metabolism and energy

• Correcting nutrient deficiencies when present

• Improving sleep and stress regulation

• Supporting gut health and absorption

• Addressing inflammation or autoimmune triggers

• Creating a realistic, sustainable treatment plan

Our goal is meaningful improvement without unnecessary supplements, testing, or medication.

Comprehensive Thyroid Testing

Many thyroid conditions are missed when only TSH is measured. Depending on your symptoms and medical history, we may recommend a more comprehensive assessment to better understand thyroid function and identify contributing factors.

Testing may include:

• TSH
• Free T4
• Free T3
• Thyroid peroxidase (TPO) antibodies
• Thyroglobulin antibodies
• Iron studies (including ferritin)
• Vitamin B12
• Vitamin D
• Blood sugar and insulin markers when appropriate

As naturopathic doctors in Ontario, we can order these laboratory tests directly. While some thyroid tests are not covered by OHIP when ordered by a naturopathic doctor and are paid for privately, they often provide valuable information that helps us identify underlying causes of persistent symptoms and develop a more personalized treatment plan. We will always discuss the potential benefits, costs, and whether testing is appropriate before ordering any investigations.

Our goal is to recommend only the tests that are likely to change treatment decisions, not unnecessary testing.

Prescription Thyroid Hormone: When Is It Appropriate?

Many people wonder whether thyroid hormone medication is necessary or whether they should switch to a different medication if they continue to have symptoms.

While levothyroxine is the standard treatment for most people with hypothyroidism, some patients continue to experience fatigue, brain fog, weight gain, or other symptoms despite normal blood tests. In selected cases, other thyroid hormone options, including desiccated thyroid hormone, may be appropriate.

As naturopathic doctors with prescribing rights in Ontario, we can assess whether medication is indicated, review your current thyroid treatment, and discuss whether changes are appropriate based on your symptoms, blood work, medical history, and current evidence.

Medication is only one part of treatment. We also investigate nutrition, iron status, gut health, inflammation, stress, sleep, and other factors that commonly affect thyroid function and how you feel.

Our goal is to help you feel better—not simply normalize your lab results.

FAQ

Is Desiccated Thyroid Hormone Better Than Levothyroxine?

Many patients ask whether Armour Thyroid or desiccated thyroid hormone is better than levothyroxine. For most people, levothyroxine works well, but some continue to experience symptoms despite normal blood tests. In selected cases, alternative thyroid hormone options may be appropriate. Treatment decisions are individualized and based on symptoms, laboratory results, medical history, and current clinical evidence.

We assess the complete clinical picture, including symptoms, thyroid function, nutrient deficiencies, sleep, stress, gut health, and other medical conditions that may contribute to persistent symptoms.
