Understanding the Why Behind Your Symptoms
Autoimmune conditions can feel overwhelming, unpredictable, and deeply personal. Many people spend years trying to understand what’s happening in their bodies—shuffled between specialists, told their tests look “fine,” or offered treatment that manages symptoms but doesn’t explain them.
At Mosaic Medical, we take a different approach.
Instead of viewing an autoimmune condition as a series of isolated symptoms, we look at the whole picture—your history, your environment, your biology, and the deeper triggers shaping your immune system. Autoimmunity is complex, but there is always a story behind it. Our job is to help you uncover it.
Our team of Functional Medicine doctors, including Dr Isobel Wilson, Dr Priya Bhana, Dr Andie Siggers and Dr Emily Lacey, have extensive experience supporting patients with autoimmune disease. Their work combines rigorous medical training with a root-cause, systems-based model designed to bring clarity, direction, and long-term improvement.
What Is Autoimmunity?
Autoimmune conditions occur when the immune system—designed to protect you—becomes dysregulated and mistakenly attacks your own tissues. For some, symptoms develop gradually; for others, they appear suddenly or after periods of stress, infection, hormonal shifts or environmental exposure.
Common autoimmune conditions we support include:
- Hashimoto’s thyroiditis and Graves’ disease
- Rheumatoid arthritis and psoriatic arthritis
- Lupus (SLE)
- Psoriasis and eczema with autoimmune features
- Coeliac disease
- Multiple sclerosis
- Autoimmune gastritis
- Ulcerative colitis and Crohn’s disease (IBD)
- Sjögren’s syndrome
- Autoimmune neuropathies
- Autoimmune urticaria and mast cell–related disorders
Whether you have a formal diagnosis or simply a constellation of unexplained symptoms, we help you understand what may be driving inflammation and immune imbalance.
Why Autoimmune Conditions Are So Difficult to Resolve
Many patients reach us after months or years of feeling unheard. They’ve been told there’s nothing more to try, or that their symptoms don’t fit neatly into one diagnosis. Some have been prescribed medication that eases symptoms temporarily but doesn’t prevent future flare-ups.
The truth is:
Autoimmunity rarely comes from a single cause.
It is almost always the result of numerous interconnected factors.
Common underlying drivers include:
- Chronic inflammation
- Gut barrier dysfunction and microbiome imbalance
- Viral reactivation or unresolved infections
- Hormonal shifts (e.g. menopause, postpartum changes, thyroid dysregulation)
- Nutrient deficiencies
- Blood sugar instability or metabolic stress
- High stress and circadian disruption
- Genetic predisposition
Conventional medicine addresses the immune system’s response.
Functional Medicine also asks: what triggered it? What is sustaining it? And how can we restore balance at the source?
Our Root-Cause Approach to Autoimmunity
We Listen to Your Story
Autoimmunity never occurs in isolation.
Your symptoms, stress, nutrition, sleep, history of infections, medications, trauma and environment all shape the immune landscape. Understanding your timeline often reveals connections that standard appointments miss.
We Investigate What’s Driving Immune Dysregulation
Using targeted, evidence-informed testing, we explore:
- Inflammatory pathways
- Autoantibodies
- Gut permeability and microbiome health
- Hormonal balance
- Nutrient status
- Mould and toxin exposure
- Viral or immune activation patterns
- Mitochondrial and metabolic function
Our goal is to understand why your immune system is reacting—not simply suppress the reaction.
We Connect the Dots
Autoimmune symptoms usually reflect deeper systemic imbalances.
We map how your digestive system, hormones, immune pathways and nervous system influence each other to identify the true drivers behind your condition.
We Personalise Your Plan
Your plan may include:
- Personalised nutrition to lower inflammation and support immune resilience. Where appropriate, your doctor will also work closely with our Registered Nutritional Therapist to ensure you receive expert, integrated support for your nutrition
- Gut-healing strategies
- Targeted nutraceuticals and supplements
- Hormone optimisation
- Stress, sleep and circadian support
- Medication adjustments where appropriate
- Genetic considerations where helpful
Your plan is built uniquely for you—never a generic protocol.
We Support You Over Time
Your body changes as healing unfolds.
We adapt your plan, monitor your progress, and walk with you through each step. Autoimmune healing is not linear, and you do not have to navigate it alone.
Case Study:
Sarah’s Journey with Hashimoto’s Thyroiditis
Shared with permission; details anonymised.
Although conventional treatment managed some of her symptoms, she continued to struggle with profound fatigue and persistent digestive discomfort. She felt there must be more to the story.
During her consultation at Mosaic Medical, we explored her symptoms in detail and carried out targeted functional testing. This revealed:
- multiple food sensitivities
- significant gut microbiome imbalance
- elevated thyroid antibodies indicating active thyroid inflammation
We built a personalised plan that included eliminating trigger foods, supporting gut repair, and incorporating stress-regulating practices such as yoga and meditation. Over the following months, Sarah experienced a striking improvement in her digestion, energy, mood and overall wellbeing.
At the same time, we monitored her thyroid antibodies, which decreased steadily—a sign that immune activity against the thyroid was calming.
During our regular Endocrinology multidisciplinary meeting, we reviewed Sarah’s case with Consultant Endocrinologist Dr Natasha Patel. Additional testing revealed that Sarah carried a genetic variation in the DIO2 gene, which affects the conversion of T4 to the active T3 hormone. Her symptom pattern, blood work and genetic results indicated she might benefit from a trial of T3 therapy.
With specialist input and careful supervision, we adjusted her thyroid medication.
Sarah noticed a transformative improvement—her energy returned, her cognitive clarity improved, and she finally felt like herself again.
With Sarah’s consent, her GP was kept updated throughout her care, ensuring a collaborative and joined-up approach.

FAQs
Do I need a formal autoimmune diagnosis to see you?
No. We support patients with confirmed diagnoses as well as those experiencing symptoms that suggest early or undetected immune imbalance.
Can you work alongside my NHS consultant?
Yes. Collaboration is central to our model. We regularly work alongside rheumatology, endocrinology, dermatology and gastroenterology specialists. Any medication adjustments are done only with their agreement.
Can Functional Medicine replace my medication?
We never remove or reduce medication without a controlled, medically supervised plan. Our approach complements rather than replaces conventional care, helping your body function more optimally.
How long does it take to see improvement?
While every case is different, many patients notice improvements within weeks. Deeper immune regulation can take months, but we focus on sustainable, long-term change, not quick fixes.
