What Is Autoimmune Disease? Symptoms & Causes

I regularly see patients who describe a cluster of symptoms that don't quite add up - persistent fatigue, joints that ache for no obvious reason, skin that flares unpredictably, or a general sense that something isn't right, despite otherwise looking well. One of the most common concerns I see in practice is a patient asking, "Could this be autoimmune?" - often after weeks of feeling dismissed or told it's "just stress."

It's a fair question, and an increasingly common one. This article explains what autoimmune disease actually means, what the most common autoimmune disease symptoms look like, and how conditions such as rheumatoid arthritis - one of the best-known examples - are diagnosed and managed in the UK.

A patient I saw a while ago - a woman in her early thirties - had spent the best part of two years being treated for "stress" and mild anaemia before a wider blood panel picked up thyroid autoantibodies consistent with Hashimoto's thyroiditis. Her story isn't unusual. It's one of the more common patterns I see with autoimmune disease generally: vague, fluctuating symptoms that get attributed to lifestyle or mental health long before anyone thinks to test for an underlying immune cause.

Quick Answer: What Is Autoimmune Disease?

Autoimmune disease is an umbrella term for more than 80 different conditions in which the immune system mistakenly attacks the body's own healthy tissue instead of just fighting infection. Depending on which tissues are targeted, this can affect a single organ - as in autoimmune thyroid disease - or multiple systems throughout the body, as seen in rheumatoid arthritis or lupus.

How Does the Immune System Normally Work?

Before explaining what goes wrong in autoimmune disease, it helps to understand what your immune system is meant to do. In simple terms:

Many patients are surprised to learn that autoimmune disease isn't a sign of a "weak" or "overactive" immune system in the way people often assume - it's really a case of mistaken identity. If you'd like a broader primer on immune function generally, we've covered how your immune system works in more detail elsewhere on the blog.

What Is Autoimmune Disease, Exactly?

In autoimmune disease, the immune system loses the ability to reliably tell the difference between "self" and "non-self." It produces antibodies - called autoantibodies - that target the body's own cells, triggering inflammation and, over time, tissue damage.

How Common Is Autoimmune Disease in the UK?

Autoimmune disease is far more common than most people assume. A large 2023 study of 22 million UK health records, led by researchers at Oxford University and UCL, found that these conditions affect around 10% of the population - roughly 13% of women and 7% of men - a notably higher figure than earlier estimates of 3-9%. This kind of large-scale data matters because individually, many autoimmune conditions are rare, which historically made overall prevalence difficult to pin down.

Organ-Specific vs Systemic Autoimmune Disease

One distinction I find useful when explaining this to patients is whether a condition is organ-specific or systemic.

Type	Common Examples	Main Target	Typical Symptoms
Organ-specific	Autoimmune thyroid disease, type 1 diabetes, coeliac disease	A single organ or tissue	Symptoms specific to that organ – for example, weight change and fatigue in thyroid disease, or thirst and weight loss in type 1 diabetes
Systemic	Rheumatoid arthritis, lupus, Sjögren's ‍ Common Types of Autoimmune Disease Rheumatoid Arthritis: The Most Widely Recognised Example Rheumatoid arthritis (RA) is probably the autoimmune condition most people have heard of, and it's a useful illustration of how these diseases behave. In RA, the immune system attacks the synovium - the lining of the joints - causing pain, swelling and stiffness that's typically symmetrical and worse first thing in the morning. A question I am frequently asked is whether joint pain automatically means RA. It doesn't - but persistent, symmetrical joint stiffness lasting more than half an hour each morning is exactly the kind of pattern that NICE's guidance on RA management says warrants urgent specialist referral rather than being dismissed as "wear and tear." Patient charities such as Versus Arthritis also offer excellent further reading. I've written a detailed guide to rheumatoid arthritis, covering its symptoms, causes, and treatment in far more depth, since it deserves a fuller explanation than this overview can provide. Other Common Autoimmune Conditions Beyond RA, some of the autoimmune diseases I see most often in clinic include: Lupus (systemic lupus erythematosus) - a systemic condition that can affect joints, skin, kidneys and other organs, often causing a distinctive facial rash and disproportionately affecting women of childbearing age Type 1 diabetes - the immune system destroys insulin-producing cells in the pancreas, usually presenting with thirst, frequent urination and weight loss, as NHS information on the condition sets out in more detail; diabetes testing can help confirm a diagnosis when these symptoms appear, and Diabetes UK is a well-established source of ongoing patient support Coeliac disease - the immune system reacts to gluten, damaging the lining of the small intestine and, according to NHS, affecting roughly 1 in 100 people in the UK; we've covered coeliac disease in more detail separately Autoimmune thyroid disease - including Hashimoto's thyroiditis (underactive thyroid, causing fatigue and weight gain) and Graves' disease (overactive thyroid, causing weight loss and a racing heart) Psoriasis and psoriatic arthritis - affecting the skin, and sometimes the joints, with flares often triggered by stress or infection Multiple sclerosis (MS) - affecting the brain and spinal cord, with symptoms ranging from visual disturbance to problems with coordination Vitiligo - affecting pigment-producing skin cells, causing patches of skin to lose their colour Autoimmune Disease Symptoms Individual autoimmune conditions have their own specific features, but there's also a set of overlapping symptoms that many share, which is precisely why these conditions are so easy to miss early on: Persistent fatigue that doesn't improve with rest Joint or muscle pain and stiffness Low-grade fevers Skin changes - rashes, dryness, or unusual pigmentation Hair thinning or loss Digestive symptoms such as bloating or altered bowel habits "Brain fog" - difficulty concentrating or word-finding Swollen glands Why Autoimmune Symptoms Are Easy to Miss Many patients are surprised to learn just how long it can take to reach an autoimmune diagnosis, sometimes years. A few reasons for this come up repeatedly in my clinical experience: Early symptoms overlap heavily with common, less serious causes of fatigue, such as poor sleep or stress Symptoms often fluctuate, so they can seem to resolve before a pattern becomes clear Many autoimmune conditions have no single definitive test - diagnosis relies on a combination of clinical picture, blood results and, sometimes, imaging or biopsy Some people test negative on standard antibody panels despite having a genuine autoimmune condition What Causes Autoimmune Disease? As with rheumatoid arthritis specifically, the honest answer for autoimmune disease as a whole is that we don't fully understand what triggers it. What we do know points to an interaction between genetics and environment. Genetics. Certain genes, particularly within the HLA (human leukocyte antigen) system, are linked to increased risk across multiple autoimmune conditions. Having a family member with one autoimmune disease modestly raises the risk of developing another, even a different one. Sex and hormones. Women are affected far more often than men across most autoimmune diseases - sometimes two to three times as often, and considerably more for conditions like lupus. The reasons aren't fully settled, but hormonal and genetic factors are both thought to play a part. Environmental triggers. Infections, smoking, and certain medications have all been linked to triggering autoimmune activity in genetically susceptible people. Gut health. There's growing research interest in the role of the gut microbiome in regulating immune function, though this remains an evolving area. Vitamin D status. Reduced vitamin D levels have been associated with several autoimmune conditions, although whether low vitamin D is a cause or simply a consequence of chronic inflammation is still debated. Stress. While stress doesn't cause autoimmune disease on its own, many patients report that flares coincide with particularly stressful periods, and this pattern is increasingly recognised in research too. How Are Autoimmune Diseases Diagnosed? Diagnosis usually follows a similar pattern regardless of which condition is suspected: A detailed history and examination, looking for patterns - which joints, which organs, how symptoms have evolved over time Autoantibody blood testing. Blood tests commonly used include ANA (antinuclear antibody, a general screening test for several systemic conditions), rheumatoid factor and anti-CCP antibodies for RA, and condition-specific markers such as TPO antibodies for thyroid disease or tissue transglutaminase antibodies for coeliac disease Inflammatory markers, such as CRP and ESR, to gauge how active any inflammation is Imaging or biopsy, where relevant - for example, X-rays for joint damage in RA, or a gut biopsy to confirm coeliac disease Specialist referral. Depending on which organ system is affected, this might mean a rheumatologist, endocrinologist, gastroenterologist, dermatologist or neurologist. Getting a referral to the right specialist promptly matters, since several autoimmune conditions respond better to treatment started early A question I am frequently asked is whether a negative blood test rules out autoimmune disease. It doesn't, necessarily - some patients are "seronegative" on standard panels yet still have a genuine autoimmune condition based on their clinical picture, and diagnosis sometimes needs to be revisited over time as the disease evolves. How Is Autoimmune Disease Treated? Treatment varies enormously depending on which condition and which organs are involved, but some broad principles apply across most autoimmune diseases: Suppressing or modulating the immune response - using medicines ranging from short-term steroids to long-term disease-modifying drugs and biologics, as used in RA Replacing what's lost. In type 1 diabetes, this means insulin; in autoimmune thyroid disease, thyroid hormone replacement Removing the trigger where possible. In coeliac disease, a strict lifelong gluten-free diet is the primary treatment Symptom control, alongside disease-specific treatment - pain relief, skin treatments, or physiotherapy depending on what's affected Regular monitoring, since most autoimmune conditions need periodic blood tests and specialist review to track disease activity and treatment safety over time There's no single "cure" for autoimmune disease as a category, and I think it's important to be upfront about that rather than overstate what treatment can achieve. However, many autoimmune conditions - RA included - can be brought into remission or low disease activity with early, well-managed treatment, allowing most patients to lead full and active lives. Living With an Autoimmune Disease Day-to-day management goes well beyond medication. A few things I discuss regularly with patients: Pacing fatigue. Chronic fatigue from autoimmune disease doesn't always respond to rest the way ordinary tiredness does, and learning to pace activity is often more helpful than pushing through or resting completely Mental health. Living with an unpredictable, chronic condition takes a genuine toll, and low mood or anxiety are common, legitimate parts of the picture rather than something to push aside; support for depression and anxiety is a reasonable thing to ask for alongside physical treatment Flare planning. Most autoimmune conditions fluctuate, and having a plan for flare-ups - who to contact, what to adjust - reduces a lot of the anxiety around unpredictability Coordinated care. Where more than one autoimmune condition or specialist is involved, keeping your GP in the loop as the central point of contact helps prevent things falling between gaps Family planning. Some autoimmune medications aren't safe in pregnancy, and certain conditions, including lupus, need specialist input well before conception, so it's worth raising this early if it's relevant to you Common Myths and Misconceptions About Autoimmune Disease "It's basically the same as having allergies." Allergies involve the immune system overreacting to something harmless from outside the body. Autoimmune disease involves the immune system attacking the body's own tissue - a different mechanism entirely. "Only older people get autoimmune diseases." Many autoimmune conditions, including lupus and type 1 diabetes, commonly present in children, teenagers and young adults. Others, like RA, most often appear in mid-life but can occur at any age. "If your blood tests are normal, you don't have an autoimmune disease." As above, some genuine autoimmune conditions present with normal or borderline results on standard testing, particularly early on. "Diet alone can cure autoimmune disease." Diet can play a supportive role - and is the actual treatment for coeliac disease specifically - but for most autoimmune conditions, there's no dietary approach proven to replace medical treatment. "All autoimmune diseases are essentially the same condition." They share a broad mechanism, but they behave very differently depending on which tissues are affected, which is why treatment is tailored to the specific diagnosis rather than applied generically. When Should You See a GP? I'd generally encourage anyone to seek an assessment if they notice: Persistent fatigue that doesn't improve with adequate rest Joint pain, swelling or stiffness lasting more than a few weeks Unexplained skin changes, rashes or hair loss Recurrent low-grade fevers without an obvious cause A family history of autoimmune disease alongside new, persistent symptoms If getting a timely appointment is proving difficult, you can book an online GP consultation as a starting point for assessment and, where appropriate, onward referral. Frequently Asked Questions What are the first signs of autoimmune disease? Early signs often include persistent fatigue, joint or muscle pain, low-grade fevers, and skin changes, though the exact pattern depends heavily on which condition is involved. What is the most common autoimmune disease? Autoimmune thyroid disease is among the most common overall, while rheumatoid arthritis is one of the most widely recognised, affecting around 1% of UK adults. Can autoimmune disease be cured? No, most autoimmune diseases can't be cured, but many can be well controlled with appropriate treatment, allowing periods of remission or low disease activity. Are autoimmune diseases hereditary? Genetics play a meaningful role and having a family member with an autoimmune condition raises your own risk, but inheritance isn't straightforward or guaranteed. Why are autoimmune diseases more common in women? The exact reasons aren't fully understood, but hormonal and genetic factors are both thought to contribute, and the pattern is consistent across most autoimmune conditions. What blood tests check for autoimmune disease? Common tests include ANA as a general screen, plus condition-specific antibodies such as rheumatoid factor and anti-CCP for RA, TPO antibodies for thyroid disease, and tissue transglutaminase antibodies for coeliac disease. Can stress trigger autoimmune disease? Stress alone doesn't cause autoimmune disease, but many patients notice flares coinciding with stressful periods, and this link is increasingly supported by research. Is rheumatoid arthritis an autoimmune disease? Yes. In RA, the immune system attacks the lining of the joints, making it a systemic autoimmune condition rather than simple wear-and-tear arthritis. Can you have more than one autoimmune disease at the same time? Yes, autoimmune conditions can and do overlap, which is one reason diagnosis can sometimes take longer than expected. When should I see a GP about possible autoimmune symptoms? See a GP if you have persistent fatigue, ongoing joint or skin symptoms, or recurrent unexplained fevers lasting more than a few weeks, particularly alongside a family history of autoimmune disease.

Psoriasis and psoriatic arthritis - affecting the skin, and sometimes the joints, with flares often triggered by stress or infection
Multiple sclerosis (MS) - affecting the brain and spinal cord, with symptoms ranging from visual disturbance to problems with coordination
Vitiligo - affecting pigment-producing skin cells, causing patches of skin to lose their colour

Autoimmune Disease Symptoms

Individual autoimmune conditions have their own specific features, but there's also a set of overlapping symptoms that many share, which is precisely why these conditions are so easy to miss early on:

Persistent fatigue that doesn't improve with rest
Joint or muscle pain and stiffness
Low-grade fevers
Skin changes - rashes, dryness, or unusual pigmentation
Hair thinning or loss
Digestive symptoms such as bloating or altered bowel habits
"Brain fog" - difficulty concentrating or word-finding
Swollen glands
