Functional Medicine for Thyroid Conditions with Mosaic Medical
The Autoimmune Connection
- Underactive Thyroid (Hypothyroidism): the majority of people with an underactive thyroid have Hashimoto’s thyroiditis. Thyroid antibodies are not part of the standard NHS blood panel, so many people are managing an autoimmune condition without knowing it. Our article on Hashimoto’s thyroiditis explains this in more detail.
- Overactive Thyroid (Hyperthyroidism): many people with an overactive thyroid also have an underlying autoimmune driver, usually Graves’ disease.
- Relentless fatigue and exhaustion, or conversely jittery nervous energy
- Unexplained weight changes, either stubborn weight gain or unexpected weight loss
- Brain fog, poor concentration, or low mood and anxiety
- Hair thinning, brittle nails, dry skin, or excessive sweating
- Palpitations, tremors, or feeling constantly cold or overly hot
Specialist Collaboration & Tailored Medication
How Functional Medicine Addresses the Underlying Cause
- Gut Health & Systemic Inflammation: a significant portion of your immune system sits in your gut, so we look at intestinal permeability and microbiome imbalances that can fuel autoimmune thyroid activity.
- Nutrient Deficiencies: your thyroid cannot manufacture or convert hormones without key raw materials, so we test for and optimise selenium, zinc, iodine, ferritin and vitamin D.
- Stress & The HPA Axis: chronic stress alters how your brain signals your thyroid, and high cortisol can block the conversion of inactive thyroid hormone into its active form.
- Environmental triggers: we look at heavy metals, chronic viral reactivation, food sensitivities and endocrine disruptors that can interfere with thyroid receptors or confuse the immune system.

- Safe prescribing from GMC-registered doctors, alongside supplements, nutrition and lifestyle interventions
- Collaboration with a consultant endocrinologist at no extra cost, to ensure safe prescribing
- Integrated nutrition support from our registered nutritional therapist where it will help
- Patient education, so you can manage your condition for life
Common Root Causes We Investigate

- Food sensitivities, especially gluten and dairy
- Chronic infections such as EBV, H. pylori and SIBO
- Nutrient depletion, including selenium, iron, zinc and vitamin D
- Environmental toxins and endocrine disruptors
- HPA axis and adrenal imbalances

Faqs About Thyroid Conditions and Functional Medicine
Do you test for thyroid antibodies like TPO and TG?
Yes. We check TSH, free T3, free T4, reverse T3, and thyroid antibodies (TPO, TG) to give a full picture of thyroid function and autoimmunity.
Can functional medicine reverse Hashimoto’s or Graves’?
We have seen patients whose blood tests no longer show signs of autoimmune thyroid disease. However, the autoimmune process cannot be fully reversed and relapses can occur if triggers resurface. Our focus is on long-term management and reducing autoimmune activity.
Do I have to stay on thyroid medication forever?
It depends. Some patients reduce dosage, but others need long-term support depending on thyroid damage before treatment begins. For example, if you’ve been on levothyroxine for 10 years, it is unlikely to be stopped completely, but we can help optimise your health and improve how you feel.
Can you help if I have had my thyroid removed or ablated?
Yes. Even without a thyroid gland, the immune and metabolic imbalances that led to the disease remain important to address.
Do you prescribe T3?
Yes, for those who clearly benefit. This is done with input from our Consultant Endocrinologist, with careful monitoring of blood tests and symptoms. We may also suggest genetic testing to understand whether you convert T4 to T3 optimally before prescribing.
Do you offer remote consultations?
Yes. We support patients virtually across the UK, and also in person if clinically needed.
How do appointments work?
Your first appointment is 90 minutes, with your doctor reviewing your case beforehand. During this consultation, we will discuss your symptoms, history, and next steps, including any testing.
Does the appointment price include testing?
No. Testing is charged separately and only recommended if it will directly influence your management.
I already have test results and a diagnosis. Can you still help?
Yes. You can upload your results in advance. If there are many, there may be a small preparation fee, but this will be agreed with you beforehand.
How does the nutrition side work?
Nutrition is key to thyroid health. We provide personalised dietary guidance, and in complex cases, we recommend working with our nutritional therapist alongside your doctor for more comprehensive support.
