Autoimmune Diseases: Causes, Symptoms, and Treatments
Ever feel like your body is working against you? Not in the “I ate too much pizza and now I regret it” kind of way, but more like your immune system is throwing a tantrum for no reason. Welcome to the mysterious, confusing, and often frustrating world of autoimmune diseases, where your body’s defence system forgets who the real enemy is and starts attacking… well, you.
With over 100 known autoimmune conditions and millions affected worldwide (yep, you’re not alone), let’s untangle what’s happening behind the scenes. And no, this isn’t one of those cold, clinical articles that make you snooze halfway through. We’re keeping it real, relatable, and packed with genuinely helpful info you can actually use.
What are autoimmune diseases?
Imagine your immune system as a highly trained security team, working round the clock to detect and eliminate threats like viruses, bacteria, and other harmful intruders. In autoimmune diseases, however, this defence system gets confused. Instead of protecting your body, it mistakenly launches attacks on your own healthy cells and tissues.
This internal misfire can affect almost any part of the body - joints, skin, muscles, blood vessels, organs, or even hormone-producing glands. As a result, symptoms can range widely depending on the organ or system involved.
Common Autoimmune Diseases:
1. Rheumatoid arthritis: Causes chronic inflammation of the joints, leading to pain and stiffness. It’s among the most prevalent autoimmune conditions in India, especially in women over 40.
2. Lupus (Systemic Lupus Erythematosus): A complex condition that can affect the skin, joints, kidneys, heart, and more. It disproportionately affects young women and is on the rise in urban India.
3. Psoriasis: An immune-mediated skin condition that speeds up skin cell turnover, resulting in red, scaly patches. Around 0.44–2.8% of Indians are affected.
4. Type 1 diabetes: The immune system destroys insulin-producing cells in the pancreas, leading to lifelong dependence on insulin. India is home to one of the highest numbers of children with Type 1 diabetes.
5. Celiac disease: In this condition, gluten triggers an immune reaction in the small intestine. Though underdiagnosed in India, newer studies estimate a prevalence of 1.04% among Indian children.
6. Multiple sclerosis (MS): An unpredictable disease where the immune system targets the nervous system. Although considered rare in India, its incidence is gradually increasing, particularly in metro cities.
7. Hashimoto’s thyroiditis: A leading cause of hypothyroidism in India, especially among women. It causes fatigue, weight gain, and mood disturbances.
8. Graves’ disease: The most common cause of hyperthyroidism in India, it leads to symptoms like anxiety, weight loss, and heart palpitations.
Did you know? A recent study published in the International Journal of Clinical Biochemistry and Research reported a 30% rise in autoimmune disorders among the Indian population since the COVID-19 pandemic, with younger individuals disproportionately affected. Despite this surge, awareness remains low, and women are 2–3 times more likely to be affected than men.
What causes autoimmune diseases?
Here’s the million-dollar question: Why does the immune system suddenly flip out?
Well, there’s no single answer. Dr. Nahid Khilji, founder of Health Hatch, a wellness company, explains it like this: “The immune system accomplishes this by releasing proteins known as auto-antibodies, which attack the body’s own organs. This also causes a lot of inflammation. Chronic inflammation is a common symptom of autoimmune disorders.” Depending on the type of autoimmune disease, different parts of the body get affected.
Some other possible causes of autoimmune diseases might be:
- Genetics: If autoimmune conditions run in your family, your risk is higher.
- Infections: Some viruses and bacteria may act like molecular doppelgängers, tricking your immune system into attacking your own tissues; this is known as molecular mimicry. It’s been suggested in diseases like multiple sclerosis and rheumatic fever.
- Environmental Triggers: Exposure to certain chemicals, heavy metals, or even smoking can trigger autoimmune flare-ups. For instance, smoking is a known risk factor for rheumatoid arthritis and Graves’ disease.
- Hormones: Autoimmune diseases disproportionately affect women; around 80% of all autoimmune patients are female, which suggests hormones like estrogen may be involved.
- Gut Health: There’s growing evidence that an imbalanced gut microbiome can confuse the immune system. People with celiac disease or type 1 diabetes often show gut-related changes even before symptoms appear.
What are the symptoms of autoimmune diseases?
Honestly? It can be a wild ride. Autoimmune symptoms are tricky; they often mimic other conditions and fluctuate over time. But some common red flags include:
- Fatigue that feels bone-deep
- Swollen or painful joints
- Muscle aches or weakness
- Skin rashes (especially with lupus or psoriasis)
- Low-grade fever
- Hair loss
- Brain fog or trouble concentrating
- Digestive problems (especially in celiac or Crohn’s disease)
- Weight changes or temperature sensitivity (common in thyroid-related conditions like Hashimoto’s thyroiditis or Graves’ disease)
If you’re checking off multiple symptoms and no one can give you a straight answer, an autoimmune disease might be worth investigating.
How are autoimmune diseases diagnosed?
There’s no “one test to rule them all.” Instead, doctors often combine:
- Blood tests (like ANA, CRP, or ESR)
- Organ-specific markers (like TSH for thyroid or anti-CCP for RA)
- Imaging (like MRIs for multiple sclerosis or joint scans for rheumatoid arthritis)
- Biopsies (especially for celiac or lupus-related skin rashes)
You’ll probably go through a trial-and-error phase before landing on a diagnosis, and Autoimmune diseases are notorious for being elusive.
What’s the best treatment for autoimmune diseases?
There’s no magic pill to “cure” autoimmune diseases (yet!), but treatments can help manage symptoms and prevent flare-ups. Here's the typical game plan:
1. Medications
- Immunosuppressants (like methotrexate or azathioprine)
- Biologics (such as adalimumab or infliximab for rheumatoid arthritis and psoriasis)
- Steroids (helpful in emergencies, but not ideal long-term)
- Hormone replacement (like insulin for type 1 diabetes or levothyroxine for Hashimoto’s)
2. Lifestyle Tweaks
- Anti-inflammatory diet: Whole foods, lots of fibre, and minimal sugar can help ease symptoms.
- Regular gentle movement: Think yoga, swimming, or walking to support joint and muscle health.
- Stress reduction: Meditation, therapy, journaling—whatever calms your nervous system helps your immune system, too.
3. Specialist Support
- Rheumatologists, endocrinologists, dermatologists, or neurologists, depending on your condition.
Can autoimmune diseases be prevented?
That’s a tricky one. You can’t always prevent them, especially if your genes are loaded. But you can potentially lower your risk or delay the onset with:
- A gut-friendly diet (fermented foods, fibre, prebiotics)
- Avoiding smoking and unnecessary antibiotic use
- Managing stress effectively
- Regular exercise
- Monitoring thyroid and blood sugar levels if you have a family history
Which autoimmune diseases are the most common?
Some of the most common autoimmune diseases are:
- Rheumatoid Arthritis: Affects ~1% of the population; leads to joint inflammation and deformity over time.
- Lupus: Systemic Lupus Erythematosus (SLE) can target skin, kidneys, joints, and more. It’s sneaky and varies from person to person.
- Psoriasis: A skin condition where immune cells speed up skin cell production, leading to scaly, itchy patches.
- Type 1 Diabetes: The immune system destroys insulin-producing cells in the pancreas. Usually begins in childhood.
- Celiac Disease: Eating gluten triggers an immune attack on the small intestine.
- Hashimoto’s Thyroiditis: A common cause of hypothyroidism, leading to fatigue, weight gain, and depression.
- Graves’ Disease: Causes hyperthyroidism, with symptoms like anxiety, fast heart rate, and bulging eyes.
- Multiple Sclerosis: A neurological disease that affects communication between the brain and the body.
Frequently Asked Questions (FAQs)
Q.1) What is the most common autoimmune disease?
The most common autoimmune disease is rheumatoid arthritis (RA), which affects around 1% of the global population. RA causes the immune system to mistakenly attack the joints, leading to pain, swelling, and stiffness. It typically affects the hands, wrists, and knees. Early diagnosis and treatment are key to preventing joint damage and improving quality of life.
Q.2) What happens if you have an autoimmune disease?
When you have an autoimmune disease, your immune system attacks your own healthy tissues, mistaking them for foreign invaders. This can lead to chronic inflammation, fatigue, joint pain, skin rashes, and organ damage, depending on the condition. Symptoms may come and go in flare-ups. Without treatment, some autoimmune diseases can worsen over time.
Q.3) How to detect autoimmune diseases?
Autoimmune diseases are detected through a combination of symptom review, blood tests (like ANA, ESR, CRP), and sometimes imaging or biopsy. Doctors look for markers of inflammation and specific autoantibodies. Diagnosis can be complex as symptoms often overlap with other conditions. Early detection improves treatment outcomes.
Q.4) How to control autoimmune disease?
Autoimmune diseases are controlled using medications like immunosuppressants, biologics, and steroids, along with lifestyle changes such as stress management, anti-inflammatory diets, and regular exercise. Identifying and avoiding triggers can reduce flare-ups. Long-term care with a specialist helps maintain remission and prevent complications. There's no cure, but symptoms can be managed effectively.
A note from MrMed
Autoimmune diseases can feel like a rollercoaster, but it’s possible to take back control. Start by tracking your personal triggers, whether it's food, stress, or changes in weather. Make rest a non-negotiable part of your routine, and never feel guilty for listening to your body. Join a support group to connect with others who truly get it, and always advocate for yourself.
