Thyroid Disorders

Overview

Thyroid disorders occur when the thyroid gland produces too much or too little thyroid hormone. Because thyroid hormones help regulate how the body uses energy, thyroid dysfunction can affect energy, weight, heart rate, digestion, mood, temperature regulation, menstrual cycles, fertility, and overall health.¹˒²˒³

At Tangible Health, we take an individualized, evidence-informed approach to thyroid care. We review your symptoms, thyroid testing, medications, nutrition, lifestyle, and overall health to identify where supportive naturopathic care may be helpful alongside appropriate medical treatment and monitoring.

What Are Thyroid Disorders?

The thyroid is a small gland in the front of the neck that produces hormones involved in metabolism and energy regulation.¹˒⁶

The two main types of thyroid dysfunction are:

  • Hypothyroidism, or an underactive thyroid, where the body does not have enough thyroid hormone²

  • Hyperthyroidism, or an overactive thyroid, where there is more thyroid hormone than the body needs³

Common autoimmune thyroid conditions include Hashimoto’s disease, which often leads to hypothyroidism, and Graves’ disease, the most common cause of hyperthyroidism.⁴˒⁵ Because thyroid symptoms can overlap with many other conditions, diagnosis requires appropriate medical assessment and blood testing.

Common Symptoms of Thyroid Disorders

Symptoms vary depending on whether thyroid hormone levels are too low or too high.

Hypothyroidism may cause:

  • Fatigue or low energy

  • Feeling unusually cold

  • Weight gain

  • Constipation

  • Dry skin or thinning hair

  • Brain fog or difficulty concentrating

  • Low mood

  • Slower heart rate

  • Heavy or irregular periods

  • Fertility difficulties²

Hyperthyroidism may cause:

  • Anxiety or irritability

  • Rapid or irregular heartbeat

  • Unexplained weight loss

  • Feeling unusually hot

  • Increased sweating

  • Trembling or shaky hands

  • Difficulty sleeping

  • Frequent bowel movements

  • Muscle weakness

  • Changes in menstrual periods³

Some thyroid disorders can also cause an enlarged thyroid or thyroid nodules, while Graves’ disease may cause eye irritation, bulging, or vision changes in some people.⁵

Causes & Contributing Factors

Thyroid disorders can develop for several different reasons.

Autoimmune Thyroid Disease
Hashimoto’s disease occurs when the immune system attacks the thyroid and can gradually reduce thyroid hormone production. Graves’ disease causes antibodies to stimulate the thyroid, leading to excess thyroid hormone.⁴˒⁵

Other Thyroid Conditions
Other causes can include thyroiditis, thyroid nodules, thyroid surgery, radioactive iodine treatment, and certain medications or medical treatments.²˒³˒⁶

Iodine Intake
Iodine is necessary for thyroid hormone production, but both too little and too much can affect thyroid function. High-dose iodine or kelp supplements should not be used routinely without an appropriate clinical reason.⁷

Our Approach to Thyroid Disorders

At Tangible Health, thyroid care begins with understanding your diagnosis, current treatment, symptoms, and overall health rather than assuming every concern is caused by the thyroid.

Your Thyroid Function
We review your thyroid history, laboratory results, medications, symptoms, and any known diagnoses such as Hashimoto’s disease or Graves’ disease. We can also help you understand commonly used thyroid tests and how they fit into your care.⁶

Your Symptoms & Overall Health
We may also assess nutrition, sleep, stress, menstrual and reproductive health, metabolic health, digestive health, nutrient status, and other conditions that may contribute to symptoms such as fatigue, hair changes, constipation, mood changes, or weight concerns. Naturopathic care is designed to complement appropriate thyroid treatment rather than replace medication when it is medically necessary.²˒³

Your Goals
Your goals may include improving energy, understanding persistent symptoms, supporting nutrition, managing an autoimmune thyroid condition, preparing for pregnancy, or gaining greater clarity around your thyroid health and treatment options.

Treatments That May Be Included

Your thyroid support plan may include:

  • Clinical nutrition to support nutritional adequacy, metabolic health, cardiovascular health, and overall well-being

  • Nutraceuticals & supplements when there is an individualized nutritional or clinical indication

  • Lifestyle medicine to support sleep, movement, stress management, and sustainable health behaviours

  • Botanical medicine when clinically appropriate, with careful consideration of thyroid medications, thyroid function, and the available evidence

  • Naturopathic counselling to support stress management, behavioural changes, and living with a chronic health condition

  • Medication and supplement review to identify potential interactions or factors that may affect thyroid treatment

  • Collaborative care with your family doctor, endocrinologist, fertility specialist, or other healthcare providers when appropriate

Thyroid supplements are not automatically beneficial. In particular, excessive iodine supplementation can worsen thyroid dysfunction in some people and should be used cautiously.⁷

What to Expect

Initial Assessment
We begin with a comprehensive review of your symptoms, thyroid diagnosis, laboratory results, medications and supplements, medical and family history, nutrition, sleep, stress, reproductive health, and treatment goals.

Targeted Testing
Thyroid testing is recommended based on your symptoms and clinical history. TSH is commonly used as an initial test, often together with or followed by free T4, while T3, thyroid antibodies, imaging, or other testing may be used when there is a specific clinical reason.⁶

Personalized Plan
Your care plan is developed around your thyroid diagnosis, laboratory findings, symptoms, medications, overall health, and goals. Recommendations may include nutrition, lifestyle support, individualized supplementation, and coordination with your existing medical treatment.

Ongoing Support
Thyroid levels and medication needs can change over time. Follow-up allows us to review symptoms and laboratory results and adjust supportive care while appropriate medical monitoring continues.

When to Seek Support for Thyroid Disorders

Consider speaking with a healthcare provider if you experience:

  • Persistent or unexplained fatigue

  • Unexplained weight gain or weight loss

  • Feeling unusually cold or hot

  • Hair thinning or significant skin changes

  • Persistent bowel changes

  • Anxiety, irritability, or low mood

  • Rapid or irregular heartbeat

  • Menstrual changes or fertility difficulties

  • Swelling or a lump in the neck

  • Abnormal thyroid blood-test results

Thyroid health is also particularly important before and during pregnancy, so people with known thyroid disease who are pregnant or planning pregnancy should discuss appropriate monitoring with their healthcare provider.⁸

Frequently Asked Questions

  • Common symptoms include fatigue, weight changes, feeling unusually hot or cold, hair or skin changes, constipation or frequent bowel movements, mood changes, and changes in heart rate. Symptoms vary depending on whether thyroid hormone levels are too low or too high.²˒³

  • Hypothyroidism means the body does not have enough thyroid hormone, which tends to slow body functions. Hyperthyroidism means there is too much thyroid hormone, which tends to speed them up.²˒³

  • Both are autoimmune thyroid disorders. Hashimoto’s commonly leads to an underactive thyroid, while Graves’ disease usually causes an overactive thyroid.⁴˒⁵

  • Thyroid disorders are diagnosed using your symptoms, medical history, physical examination, and blood tests such as TSH and free T4. Additional tests may be used depending on the suspected condition.⁶

  • It depends on the condition. People with clinical hypothyroidism often need thyroid hormone replacement, while hyperthyroidism may require medication, radioactive iodine, or surgery.²˒³

  • Yes. Both underactive and overactive thyroid function can affect menstrual cycles and fertility. Thyroid health is also important during pregnancy.²˒³˒⁸

  • Naturopathic care can support nutrition, sleep, stress, lifestyle, appropriate supplementation, and other health concerns alongside thyroid treatment. It should not replace thyroid medication or specialist care when these are medically indicated.
