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.
