Ankylosing spondylitis (AS) is a type of arthritis that mainly affects the spine. It causes inflammation in the joints, leading to stiffness, pain, and sometimes fusion of the spine. But AS doesn’t just stop at the spine. Many people with AS also develop other autoimmune conditions, including inflammatory bowel disease (IBD), psoriasis, and uveitis. This happens because the immune system, which is supposed to protect the body, becomes overactive and attacks healthy tissues.

Understanding this connection is important for managing AS and reducing the risk of other autoimmune diseases. By recognizing the signs early and making changes to reduce inflammation, you can take control of your health and improve your quality of life.

Why AS Increases the Risk of Autoimmune Conditions

AS is an autoimmune and autoinflammatory disease, meaning the immune system mistakenly attacks the body’s own tissues. While the exact cause is not fully understood, genes play a big role. One gene in particular, HLA-B27, is strongly linked to AS. Not everyone with this gene develops AS, but it increases the risk of immune system problems.

When the immune system is overactive, it doesn’t just attack the spine. It can also affect other parts of the body, such as the gut, skin, and eyes. The same inflammatory pathways that cause pain and stiffness in the back can also lead to digestive issues, skin conditions, and eye inflammation.

Autoimmune Conditions Linked to AS

Inflammatory Bowel Disease (IBD)

IBD includes Crohn’s disease and ulcerative colitis, which cause inflammation in the digestive tract. Up to 10% of people with AS also have IBD. The gut and joints share common immune pathways, which explains why they are often affected together.

Psoriasis and Psoriatic Arthritis

Psoriasis is an autoimmune skin condition that causes red, scaly patches. Some people with AS also develop psoriatic arthritis, which affects joints outside the spine. The connection lies in the immune system’s tendency to attack multiple areas of the body.

Uveitis (Eye Inflammation)

About 30-40% of people with AS experience uveitis. This condition causes eye pain, redness, and blurred vision. If untreated, it can lead to serious vision problems.

Other Conditions

People with AS may also develop:

  • Celiac disease, which causes gluten intolerance and damages the gut.
  • Reactive arthritis, a type of arthritis triggered by infections but with immune features similar to AS.

How to Manage AS and Reduce the Risk of Autoimmune Diseases

Early Diagnosis and Treatment

Seeing a rheumatologist early can help control inflammation before it spreads to other organs. Regular checkups and monitoring symptoms are important for preventing complications.

Anti-Inflammatory Diet

What you eat affects inflammation in the body. Avoid processed foods, sugar, and unhealthy fats. Instead, focus on:

  • Omega-3-rich foods like salmon and flaxseeds to reduce inflammation.
  • Antioxidant-rich vegetables to support the immune system.
  • Probiotic foods like yogurt and kimchi for gut health.

Exercise and Mobility Work

Staying active helps keep the spine flexible and prevents stiffness. Low-impact exercises like swimming, yoga, and stretching improve movement and reduce pain.

Medications for Inflammation Control

  • NSAIDs (non-steroidal anti-inflammatory drugs) help with pain and swelling.
  • Biologic treatments like TNF blockers and IL-17 inhibitors target the immune system to reduce inflammation long-term.

Regenerative Medicine and Non-Surgical Treatments

For those looking for alternative treatments, regenerative medicine offers options like:

  • Platelet-rich plasma (PRP), which uses the body’s natural healing factors to repair joint damage.
  • Prolotherapy, which strengthens ligaments and improves joint stability.

These treatments can help manage pain and support joint health after systemic inflammation is controlled.

Gut Health Matters

Since AS is closely linked to gut issues, keeping the digestive system healthy is important. Eating fiber-rich foods, taking probiotics, and avoiding inflammatory foods can help balance the gut microbiome and reduce overall inflammation.

Stress Management and Sleep Optimization

Chronic stress and poor sleep make inflammation worse. Good sleep habits, meditation, and stress-reducing activities can help regulate the immune system and keep symptoms under control.

Key Takeaways

  • Ankylosing spondylitis is linked to autoimmune conditions like IBD, psoriasis, and uveitis.
  • Chronic inflammation plays a major role in these conditions.
  • Managing AS requires a mix of early diagnosis, diet, exercise, medication, and alternative treatments.
  • Gut health, stress management, and sleep quality are key factors in reducing inflammation and improving overall well-being.
