If you've ever been told that your thyroid labs are "normal" but you still struggle with fatigue, weight changes, brain fog, or low energy, you're not alone.
At Teleios, we believe thyroid health deserves a thoughtful, individualized evaluation. While Thyroid Stimulating Hormone (TSH) is an important screening test, it doesn't always tell the whole story.
The thyroid gland produces hormones that influence nearly every organ system in your body. It plays a critical role in:
When thyroid function is disrupted, symptoms can be subtle and easily mistaken for stress, aging, or hormonal changes.
People with hypothyroidism may experience:
Symptoms may include:
Because these symptoms overlap with many other medical conditions, laboratory testing is an important part of the evaluation.
Depending on your symptoms and medical history, your provider may recommend several laboratory tests to better understand thyroid function.
TSH is often the starting point for thyroid evaluation. It reflects how the brain is signaling the thyroid gland and can help identify both underactive and overactive thyroid conditions.
Free T4 measures the amount of circulating thyroxine available to your body and provides additional insight into thyroid hormone production.
Free T3 represents the active thyroid hormone available to tissues and may be useful in selected clinical situations when interpreted alongside other laboratory values.
Tests such as thyroid peroxidase (TPO) antibodies and thyroglobulin antibodies can help identify autoimmune thyroid diseases, including Hashimoto's thyroiditis and Graves' disease.
In certain clinical scenarios, providers may order additional laboratory studies, including reverse T3 or other specialized testing. These tests are not necessary for every patient but may be considered based on individual circumstances and clinical judgment.
Many patients assume difficulty losing weight is caused by thyroid disease. While untreated hypothyroidism can contribute to weight gain, it is only one piece of a much larger picture.
Nutrition, physical activity, sleep quality, stress, medications, body composition, insulin resistance, and sex hormones all influence metabolism.
That's why Teleios takes a comprehensive approach rather than focusing on a single laboratory value.
Lab results should never be interpreted in isolation. The most effective treatment plans combine laboratory findings with your symptoms, medical history, physical examination, and overall health goals.
Our goal is to identify the root causes of your symptoms and develop a personalized strategy that supports long-term wellness and optimal performance.
If you're experiencing unexplained fatigue, weight changes, brain fog, or other persistent symptoms, a comprehensive evaluation may provide valuable answers.
The team at Teleios is here to help you understand your health and create a plan tailored to your unique needs.
