Understanding Thyroid Dysfunction: Symptoms to Watch Out For
Thyroid dysfunction often manifests in subtle, often misunderstood symptoms. These signs can vary widely, but the impact on your body can be profound. Here are the most common signs that your thyroid may not be functioning properly:
Persistent Fatigue
When your thyroid is underactive, it can significantly reduce energy production, leaving you feeling exhausted no matter how much rest you get. Persistent tiredness that doesn’t improve with sleep could indicate a thyroid imbalance.
Unexplained Weight Gain or Difficulty Losing Weight
If your metabolism is sluggish due to thyroid issues, weight gain or an inability to lose weight becomes more common. Despite diet and exercise efforts, your body’s energy expenditure might be limited, leading to frustrating weight challenges.
Sensitivity to Cold
Feeling excessively cold, even when others are comfortable, is a classic sign of hypothyroidism (underactive thyroid). This is due to slowed metabolism, which reduces the body’s ability to generate heat.
Dry Skin and Hair Thinning
Thyroid hormones play a vital role in maintaining healthy skin and hair. When levels are imbalanced, you might notice your skin becoming dry, flaky, or rough, and your hair thinning or falling out more than usual.
Depression or Anxiety
Thyroid imbalance can disrupt mood-regulating neurotransmitters in the brain, leading to feelings of depression, anxiety, or irritability. Hormones like thyroid hormone influence the production and function of serotonin, a neurotransmitter responsible for mood balance.
Brain Fog and Memory Issues
Thyroid hormones help with cognitive function. Low thyroid function can result in “brain fog,” making it difficult to focus, concentrate, or remember details.
Constipation
Digestive function can be sluggish when thyroid hormones are low, leading to constipation. If you’ve been experiencing ongoing digestive issues, it could be related to a thyroid imbalance.
Irregular or Heavy Menstrual Periods
Women with thyroid dysfunction may notice changes in their menstrual cycle, including heavier or more frequent periods. These changes are linked to hormonal imbalances that affect the reproductive system.
Low Libido
Thyroid hormones are essential for sexual function. An imbalance can lead to a reduced interest in sex, often due to low energy levels or hormonal disruptions affecting the reproductive system.
The Role of Thyroid Hormones in Total Body Balance
Your thyroid produces several essential hormones that are fundamental for maintaining balance throughout your entire body. Understanding these hormones and their roles is key to managing thyroid health effectively.
- T4 (Thyroxine): The Storage Form
- T3 (Triiodothyronine): The Active Hormone
- rT3 (Reverse T3): The Inactive Form
T4 is the inactive form of thyroid hormone and acts as a reservoir, ready to be converted into its active form, T3. It is essential for regulating metabolism, and when it’s out of balance, it can cause a variety of symptoms.
T3 is the active thyroid hormone that drives metabolism and energy production. When T3 levels are low, it can lead to fatigue, weight gain, and sluggish bodily functions. The conversion of T4 to T3 is critical for optimal health.
Reverse T3 is an inactive form of thyroid hormone that can block the action of T3. Elevated rT3 levels often occur during chronic stress, illness, or inflammation and can lead to symptoms like fatigue, weight gain, and difficulty concentrating.
The Balance is Key
The balance between T4, T3, and rT3 is essential for metabolic function. When this balance is disrupted, it can lead to significant health issues. A sluggish conversion of T4 to T3, or an increase in rT3, can cause symptoms that interfere with daily life. That’s why monitoring these hormones is crucial for understanding thyroid health fully.
Specialised Thyroid Testing: Going Beyond TSH
While most clinics focus only on testing TSH (Thyroid Stimulating Hormone), we offer a comprehensive thyroid panel that provides a complete picture of your thyroid health. This in-depth testing allows us to uncover imbalances that standard tests often miss.
Our Comprehensive Thyroid Testing Includes:
- TSH (Thyroid Stimulating Hormone): The marker most commonly used to assess thyroid function. However, TSH alone does not provide the full picture.
- Free T4 (Free Thyroxine): Measures the amount of unbound T4, giving a better indication of your thyroid function.
- Free T3 (Free Triiodothyronine): Reflects the active thyroid hormone that directly influences metabolism and energy production.
- Reverse T3 (rT3): Identifying elevated rT3 helps pinpoint functional thyroid blockages, often seen during chronic stress.
- Anti-TPO Antibodies: Detects thyroid peroxidase antibodies, which are markers for autoimmune conditions like Hashimoto’s thyroiditis.
- Anti-TG Antibodies: Detects thyroglobulin antibodies, another marker for autoimmune thyroid disease.
Why This Matters:
- Low T3: Even if TSH levels appear normal, low T3 can cause symptoms like fatigue and weight gain.
- High rT3: Elevated levels of rT3 can block T3 from functioning properly, leading to persistent symptoms of thyroid dysfunction.
- Positive Antibodies: The presence of antibodies can indicate autoimmune thyroid diseases like Hashimoto’s, often before significant changes in TSH occur.
With these tests, we can uncover hidden thyroid problems that are frequently missed by standard tests, enabling us to offer more accurate diagnoses and effective treatments
Our Functional Medicine Approach to Thyroid Health
At Hormones for Life, we take a functional medicine approach to thyroid health. This holistic approach focuses on identifying the root causes of thyroid dysfunction, rather than simply treating the symptoms. We work to restore balance and optimal function by addressing factors such as nutrient deficiencies, chronic stress, and autoimmune issues.
Root Cause Identification:
We begin by assessing factors that could be contributing to thyroid dysfunction, such as:
- Conversion issues: Difficulty converting T4 to active T3.
- Autoimmunity: Conditions like Hashimoto’s thyroiditis that attack the thyroid gland.
- Nutrient deficiencies: Essential nutrients like selenium and zinc are crucial for proper thyroid function.
- Adrenal dysfunction: Chronic stress can cause adrenal imbalances, which impact thyroid function.
Personalised Treatment Plans:
Once we’ve identified the root cause, we create a personalised treatment plan that may include:
- Bioidentical thyroid hormone support (including T3 if needed).
- Nutritional therapy: Addressing nutrient deficiencies to support thyroid function.
- Stress management: Techniques like meditation, yoga, and other therapies to reduce chronic stress.
- Autoimmune protocols: Focus on gut health, detoxification, and immune system support.
Ongoing Monitoring for Long-Term Success:
Thyroid health requires continuous monitoring. We regularly track your progress through follow-up tests, ensuring your treatment is adjusted for long-term success. This ongoing care ensures you continue to feel your best, helping to prevent future thyroid imbalances.

Frequently Asked Questions
What is the difference between T3 and T4?
T4 (thyroxine) is the inactive storage form of thyroid hormone, while T3 (triiodothyronine) is the active form that powers metabolism, energy production, and brain function. Your body must efficiently convert T4 into T3 for optimal thyroid performance.
Why is testing Reverse T3 important?
Reverse T3 (rT3) is an inactive form that blocks active T3 from working properly. High Reverse T3 often occurs under stress, illness, or inflammation and can cause symptoms of low thyroid function even if TSH appears normal. Testing rT3 reveals hidden thyroid dysfunction that standard tests miss.
Can I have thyroid symptoms even if my TSH is normal?
Yes. Many patients experience fatigue, weight issues, and mood changes despite having a “normal” TSH. Comprehensive testing, including Free T3, Free T4, and Reverse T3, is essential for diagnosing functional thyroid disorders accurately.
What are thyroid antibodies and what do they mean?
Thyroid antibodies (Anti-TPO and Anti-TG) indicate an autoimmune attack on the thyroid gland, commonly seen in conditions like Hashimoto’s thyroiditis. Early detection allows us to intervene before significant thyroid damage occurs.
How often should thyroid levels be checked?
We recommend checking thyroid levels every 3–6 months during treatment or adjustment phases, and annually once stable, to ensure ongoing optimal thyroid health
