Top Causes of Ankylosing Spondylitis: Early Signs & Guide

Introduction

Have you ever felt stiffness in your lower back, especially in the morning, and assumed it was just from a bad mattress or poor posture? For many people, that’s all it is—but for others, it’s the first sign of a chronic condition called ankylosing spondylitis. Ankylosing spondylitis (AS) is a type of inflammatory arthritis that mainly targets the spine and can slowly reduce its flexibility. Left untreated, it can lead to pain, limited movement, and even long-term spinal damage.

Many people dismiss the early signs of AS because the symptoms can seem mild or come and go. But recognizing it early is the key to slowing its progress. In this blog, we’ll explore what ankylosing spondylitis is, the causes of ankylosing spondylitis, key symptoms to watch for, and when it’s important to consult a specialist. Whether you’re concerned about your own back pain or learning more for a loved one, this guide will help you understand AS better—and take the right steps toward managing it.

Ankylosing Spondylitis

Ankylosing spondylitis is a long-term form of arthritis that mainly affects the spine. Over time, some of the small bones in the spine (vertebrae) may join together, leading to reduced flexibility. For many people, the first signs are lower-back pain and stiffness in the morning that eases with movement.

• Age group: Usually starts in late teens or twenties.
• Gender: More common in men, but women can get it too.
• Course: Some days are good, some bad—flares and remissions are typical.

A workmate once told me that his AS felt like his back was “rusty.” A short walk or hot shower often helped him loosen up, but the ache never truly went away.

Causes

Scientists still don’t know the exact reason AS develops, but they have pinpointed several key causes of ankylosing spondylitis.

1. Genetic Link (HLA-B27)
   Around 80–90% of people with AS carry a gene called HLA-B27. Having this gene does not guarantee you’ll get AS, yet it raises the risk sharply.
   Roughly 1 in 20 people with HLA-B27 will develop AS, compared to about 1 in 200 of the general population.
2. Family History
   If a parent, sibling, or child has AS, your odds of developing it rise. My friend Ravi’s older sister was diagnosed first, which pushed him to see a doctor sooner than he might have otherwise.
   This is one of the most important causes of ankylosing spondylitis to watch for, especially if there’s a known family connection.
3. Immune System Mix-Ups
   AS is considered an autoimmune or auto-inflammatory condition. The body’s defense system, which should protect you, mistakenly targets healthy joints—mostly in the spine and pelvis—leading to long-lasting swelling.
4. Environmental Triggers
   Researchers think an infection—often of the gut or urinary tract—might flip the switch in someone who is already at risk. The infection may calm down, but the immune confusion lingers. This interplay between infection and immune response is believed to be one of the environmental causes of ankylosing spondylitis.
5. Hormonal Factors
   Some small studies suggest hormones such as testosterone or estrogen might influence who develops AS and how severe it becomes, but evidence is still mixed.
6. Lifestyle Contributors
   Smoking and obesity don’t cause AS on their own, yet they can worsen inflammation and pain once the condition is present. While not direct causes of ankylosing spondylitis, these factors can amplify symptoms and disease progression.

Keyword tip: People often search for “causes of ankylosing spondylitis“ along with “genetic” or “HLA-B27,” so understanding the gene link can help you spot reliable online resources or research papers quickly.

Symptoms

AS doesn’t look the same in every person, but the most common signs include:

• Persistent dull pain in the lower back or buttocks
• Morning stiffness that improves with activity but returns after rest
• Pain that wakes you in the second half of the night
• Swelling in other joints such as hips, shoulders, or knees
• Red, painful eyes (uveitis) in up to 40% of cases
• Fatigue so strong it feels like walking through wet sand

I remember Ravi saying the eyelid pain from uveitis bothered him even more than his back flare because it appeared suddenly and blurred his vision.

Understanding the symptoms along with the causes of ankylosing spondylitis can help people seek medical help sooner, especially when multiple signs show up together.

When to See a Doctor

So, when is a stiff back just a stiff back, and when should you worry?

• Pain lasts longer than three months
• Stiffness is worse in the morning and eases with movement, not rest
• Over-the-counter pain pills stop working
• You notice eye redness or blurred vision
• A close family member has AS or another autoimmune disease

If any of these points sound familiar, book an appointment with a rheumatologist. Early care can slow joint damage and keep you moving comfortably. Many people only realize the seriousness of their symptoms after learning about the causes of ankylosing spondylitis through medical consultation or online resources.

Conclusion

Ankylosing spondylitis may start with something as common as back stiffness, but its long-term impact on your spine and daily life can be serious if left untreated. Understanding the causes of ankylosing spondylitis, recognizing early symptoms, and knowing when to seek help can make a major difference in managing this condition.

Whether it’s a genetic link, a misguided immune response, or an unknown environmental trigger, what matters most is catching it early and beginning the right treatment plan.
