    Understand Your Body

    If you are looking for specialist autoimmune disease nutrition support, you are in the right place. Autoimmune conditions are complex, often misunderstood, and frequently underserved by conventional medicine alone. Nutrition plays a powerful and evidence-backed role in modulating immune function, reducing inflammation, and supporting the body to find a more balanced state. I work with clients with a wide range of autoimmune conditions to help them understand their body, identify their triggers, and build a way of eating and living that genuinely supports long-term health.

    What Is An Autoimmune Disease?

    An autoimmune disease is a condition in which the immune system mistakenly targets the body’s own healthy cells, tissues, and organs. Instead of protecting the body from external threats, the immune system turns on itself, causing damage and chronic inflammation. There are over 90 recognised autoimmune conditions, affecting approximately four million people in the UK, which represents more than six per cent of the population.

    Common autoimmune conditions include rheumatoid arthritis, Graves’ disease, coeliac disease, type 1 diabetes, psoriasis, Crohn’s disease, ulcerative colitis, lupus, and endometriosis, among many others. Autoimmune diseases can target any organ, gland, or tissue in the body, which is why the range of symptoms is so wide. Some people experience relatively mild symptoms such as joint inflammation or fatigue, while others face more severe manifestations, including significant organ involvement.

    The causes are not fully understood, but research consistently points to a combination of genetic predisposition and environmental triggers. These triggers include gut dysbiosis, intestinal permeability, chronic stress, nutritional deficiencies, exposure to environmental toxins, infections, and dietary factors. This is precisely where nutritional therapy has so much to offer.

    Feeling Lost After Your Diagnosis?

    Being told you have an autoimmune condition can be a relief after years of unexplained symptoms, but it can also feel overwhelming. The appointments are short, the focus is on managing the condition rather than exploring why it developed, you leave with a prescription, perhaps a leaflet, and a follow-up date months away. Nobody talks to you about food, about your gut, about stress, about the environmental factors that may have contributed to your immune system becoming dysregulated in the first place.

    Many people with autoimmune conditions describe a frustrating cycle of flares followed by periods of relative stability, never quite knowing what triggered the flare or what they could do differently. Fatigue becomes a way of life. Joint pain, digestive problems, skin issues, and brain fog are accepted as an inevitable part of having the condition. This does not have to be your reality. Autoimmune disease nutrition is a specialist area of practice that looks beyond symptom management to understand the deeper drivers of immune dysfunction.

    The Gut & Autoimmunity

    One of the most significant developments in our understanding of autoimmune disease over the past two decades is the central role of the gut. Approximately 70 to 80 per cent of the immune system resides in the gut, making intestinal health inseparable from immune health. When the gut microbiome becomes imbalanced, a condition known as dysbiosis, or when the intestinal lining becomes compromised, often referred to as leaky gut or intestinal hyperpermeability, it can trigger and sustain immune dysregulation.

    Undigested food particles, bacterial toxins, and other substances that should remain inside the gut can pass through a compromised intestinal lining into the bloodstream. The immune system responds to these as foreign invaders, creating systemic inflammation. For those with a genetic tendency toward autoimmunity, this immune activation can tip the balance toward a full autoimmune response.

    Addressing gut health is, therefore, a foundational part of any autoimmune disease nutrition plan. Healing the gut lining, restoring a healthy and diverse microbiome, identifying food intolerances that drive immune reactivity, and supporting the digestive process are all critical steps in modulating autoimmune activity.

    Autoimmune Disease Nutrition

    My approach to autoimmune disease nutrition is rooted in functional medicine and personalised entirely around you. No two people with the same autoimmune diagnosis have the same picture. Your genetic background, your gut health, your stress levels, your nutrient status, your history of infections, and your diet all contribute to a completely individual presentation.

    I begin by taking a thorough case history to understand the full picture of your health, including what may have preceded or contributed to your diagnosis. Where appropriate, I use advanced functional lab testing to assess gut health, identify nutritional deficiencies, explore immune markers, and test for potential food sensitivities. This evidence-based, investigative approach means we are not guessing. We are building a plan on a clear understanding of what your body actually needs.

    From there, I work with you to implement targeted nutritional strategies to reduce inflammatory load, support gut integrity, address deficiencies, and build immune resilience. I also consider lifestyle factors, including sleep, stress, and movement, all of which have a direct and measurable impact on autoimmune activity. The goal is not just to reduce symptoms but to support your body in finding a healthier, more stable baseline.

    Conditions I Work With

    I work with clients across a broad range of autoimmune conditions. These include thyroid autoimmunity such as Hashimoto’s thyroiditis and Graves’ disease, inflammatory bowel conditions including Crohn’s disease and ulcerative colitis, rheumatoid arthritis and other inflammatory joint conditions, psoriasis and skin conditions, multiple sclerosis, coeliac disease, endometriosis, systemic lupus erythematosus, and type 1 diabetes. I also work with people who have received a suspected autoimmune diagnosis but are still in the process of getting clarity from their medical team, as well as those with a family history of autoimmunity who would like to take a proactive approach to immune health.

    My Background & Qualifications

    I’m Timea Kiss, a Registered Nutritional Therapist trained at the College of Naturopathic Medicine in London, and registered with BANT and CNHC. I am also Bsc(Hons) trained in Naturopathic Nutritional Therapy through the Institute for Optimum Nutrition (ION), validated by the University of Portsmouth. I specialise in immune health, gut health, hormonal wellbeing, and autoimmune conditions – helping people find the root causes of their symptoms rather than simply managing them.

    My passion for immune health is deeply personal. My own experience with severe allergies, asthma, and eczema that conventional medicine could not resolve led me to investigate the root causes of immune dysfunction. Through advanced functional testing, I identified severe gut dysbiosis, leaky gut, low innate immunity, H. pylori infection, and nutrient deficiencies as the underlying drivers of my own condition. Addressing these through a naturopathic approach allowed me to resolve symptoms that I had been told were permanent. That journey informs everything I do with clients, and it is why I approach autoimmune disease nutrition with both scientific rigour and genuine empathy.
