Autoimmune diseases affect millions of people across the UK, often bringing pain, uncertainty, and questions about what comes next. But here’s the good news: exciting advances in diagnosis and treatment mean more options, more hope, and more opportunities to take back control of your well-being. Whether you’ve just received a diagnosis or you’re supporting a loved one, this guide will illuminate the landscape of autoimmune conditions and the medical treatments available across the UK.
Understanding Autoimmune Diseases in the UK
What happens when your own defence system becomes your worst enemy? Autoimmune diseases occur when the immune system, designed to fight infections, mistakenly attacks healthy cells and tissues. This misfire leads to chronic conditions affecting the joints, skin, organs, or even hormonal balance.
Surprised by how common autoimmune diseases are? You’re not alone. Around 4 million people in the UK live with one or more autoimmune conditions (Autoimmune Support UK, 2023)—that’s nearly 6% of the population. Women are particularly affected, representing nearly 80% of all diagnosed cases.
The economic impact is significant too, costing the UK over £13 billion each year in health care and lost productivity. However, thanks to powerful research investment and the collaborative efforts of the NHS, medical charities, and patient groups, treatment options have improved dramatically over the last decade.
Common Autoimmune Diseases in the UK
If you think “autoimmune” is just one disease, think again! There’s a vast range of conditions, but some stand out for their prevalence and impact on daily life. Here’s a look at the most common, along with their symptoms and statistics:
1. Rheumatoid Arthritis (RA)
- Who does it affect? About 1% of the UK population (approx. 400,000 people).
- What happens? Pain, swelling, stiffness in joints, and if left untreated, potential joint deformity.
- Extra Fact: Early treatment often prevents long-term damage!
2. Type 1 Diabetes Mellitus
- Who does it affect? Around 400,000 people, including 29,000 children.
- What happens? Autoimmune destruction of insulin-producing cells in the pancreas, leading to high blood sugar.
3. Multiple Sclerosis (MS)
- Who does it affect? Over 130,000 people, especially in Scotland.
- What happens? Attacks the nervous system, causing mobility problems, fatigue, and sometimes cognitive changes.
4. Inflammatory Bowel Disease (IBD)
- Who does it affect? Around 500,000 people (includes Crohn’s Disease and Ulcerative Colitis).
- What happens? Chronic inflammation of the digestive tract, abdominal pain, diarrhoea, and weight loss.
5. Psoriasis
- Who does it affect? 1.8 million people (2–3% of UK population).
- What happens? Causes scaly, red skin patches; can also affect the joints as psoriatic arthritis.
6. Systemic Lupus Erythematosus (SLE)
- Who does it affect? 50,000 people, especially women of childbearing age.
- What happens? Can affect skin, joints, kidneys, heart, and brain, often flaring and remitting unpredictably.
7. Hashimoto’s Thyroiditis
- Who does it affect? 1–2% of the population, seven times more common in women.
- What happens? Leads to an underactive thyroid (hypothyroidism), causing fatigue, weight gain, and mood changes.
8. Graves’ Disease
- Who does it affect? Most common cause of overactive thyroid, impacting 0.5–1.3% of the population.
- What happens? The immune system stimulates the thyroid to produce too much hormone.

Accessing Treatment in the UK
Great news for UK residents! Most of these treatments are accessible via the NHS, ensuring equitable care across the country.
- Primary care GPs are often your first point of contact. After initial assessment, they refer you to hospital specialists for confirmation of the diagnosis and discussion of treatment options.
- Specialist clinics within NHS hospitals offer advanced therapies and ongoing monitoring.
- Repeat prescriptions for stable patients can often be managed in primary care.
- Technology access (for example, CGMs in diabetes or biologics for RA) is continually expanding, especially for patients who meet criteria under NICE guidelines.
- Private healthcare is available for those seeking to access specialists more quickly or for treatments not routinely funded on the NHS.
Wondering about costs? Most first-line therapies and many biologics are NHS-funded if you meet clinical eligibility. Charities like Versus Arthritis and Diabetes UK offer guidance on navigating access.

Lifestyle and Complementary Therapies
Can lifestyle make a real difference? Absolutely! While medical treatments are central, lifestyle changes and holistic approaches have a profound impact on symptoms, flares, and day-to-day quality of life.
Top lifestyle tips for managing autoimmune disease:
- Stay active: Tailored exercise keeps joints mobile, boosts energy, and supports mental health.
- Eat smart: Choose anti-inflammatory foods; some people benefit from diets low in processed foods or gluten (e.g., for coeliac disease).
- Manage stress: Meditation, mindfulness, CBT, or support groups can help reduce flares.
- Prioritise sleep: Poor sleep can worsen symptoms; develop a calming bedtime routine.
- Join a community: Groups like Versus Arthritis, MS Society, or Crohn’s & Colitis UK provide invaluable support, resources, and connections with others facing similar challenges.
Some patients also explore complementary therapies: acupuncture, yoga, aromatherapy, or nutritional supplements. While evidence varies, many report real benefits when these are used safely and alongside prescribed treatments.
Important: Always discuss new supplements or major lifestyle changes with your care team to avoid interfering with your treatment plan.
