What Actually Causes Ankylosing Spondylitis? Here's What You Should Know
If you've recently been diagnosed with ankylosing spondylitis — or you're trying to understand why someone you love has it — one of the first questions that comes to mind is: why did this happen? You're not alone in asking that. The causes of ankylosing spondylitis are something many people search for, and honestly, the answer is a bit more complex than a simple explanation.
Let's break it down in plain, simple terms.
The Main Driver: Your Genes
The biggest factor behind ankylosing spondylitis is genetics. Most people who have this condition carry a gene called HLA-B27. Research shows that around 90% of people with ankylosing spondylitis test positive for this gene.
But here's the important thing to understand — having the HLA-B27 gene does not automatically mean you'll develop the condition. In fact, many people carry this gene their entire lives and never experience any symptoms at all.
So while genetics plays a major role, it's not the only piece of the puzzle.
It's Not Just One Gene
Beyond HLA-B27, scientists have identified other genes that may contribute to the risk of developing ankylosing spondylitis. These include genes like ERAP1 and IL23R, which are involved in how your immune system functions.
This tells us that the causes of ankylosing spondylitis likely involve a combination of multiple genetic factors working together — not just a single switch being turned on.
The Role of the Immune System
Ankylosing spondylitis is an autoimmune-related condition. This means your immune system — which is supposed to protect you — starts attacking healthy tissue in your spine and joints by mistake.
Why does this happen? Researchers believe that in people with certain genetic makeups, the immune system may respond abnormally to bacteria in the gut or environment, triggering inflammation in the spine over time.
Environmental Triggers Matter Too
Genes alone don't tell the whole story. Environmental factors are believed to play a role as well. These may include:
- Gut bacteria imbalances – Some studies suggest that changes in gut microbiome may trigger immune responses linked to the condition.
- Infections – Certain bacterial infections may act as a trigger in genetically susceptible individuals.
- Physical stress or injury – Though not a direct cause, some people notice symptoms appearing after physical trauma.
Who Is More Likely to Develop It?
- People with a close family member who has the condition
- Those who carry the HLA-B27 gene
- Men, who are more commonly diagnosed than women
- People between the ages of 17 and 45
Wrapping It Up
The causes of ankylosing spondylitis come down to a mix of genetic makeup, immune system behavior, and environmental influences. No single cause explains it fully. If you're concerned about your risk, speaking with a rheumatologist is a great first step toward getting clear answers and proper care.
