As a form of arthritis, ankylosing spondylitis often starts in early adulthood and can lead to long-term complications if left untreated.
Understanding the symptoms, diagnosis, and treatment options for ankylosing spondylitis is crucial for those affected by this condition. This article aims to shed light on the key aspects of living with ankylosing spondylitis, including how to recognize its signs, the diagnostic process, and the various ways to manage and treat the disease. By exploring these topics, individuals can better navigate their journey with ankylosing spondylitis and work towards improving their overall well-being.
Understanding Ankylosing Spondylitis
Ankylosing spondylitis (AS) is a chronic inflammatory disease that primarily affects the spine and sacroiliac joints, causing pain, stiffness, and potential fusion of the vertebrae. AS is a type of axial spondyloarthritis, which can be classified as radiographic (visible on X-ray) or non-radiographic (not visible on X-ray but diagnosed based on symptoms, blood tests, and other imaging tests).
The onset of AS typically occurs in early adulthood, with inflammation affecting various parts of the body, including the eyes, cartilage between the breastbone and ribs, and hip and shoulder joints. As the disease progresses, new bone formation may occur as part of the body’s attempt to heal, potentially leading to the fusion of vertebrae and restricted movement.
What is AS?
AS is a form of arthritis that causes inflammation in the joints and ligaments of the spine. It may also affect peripheral joints like the knees, ankles, and hips. The inflammation can lead to stiffness and, in severe cases, the fusion of vertebrae, resulting in a rigid and inflexible spine.

Causes and Risk Factors
The exact cause of AS remains unknown, but genetic factors seem to play a significant role. People with the HLA-B27 gene are at a greatly increased risk of developing AS, although not everyone with this gene will develop the condition. Other risk factors include a family history of AS, age (onset generally occurs in late adolescence or early adulthood), and the presence of other conditions like Crohn’s disease, ulcerative colitis, or psoriasis.
Related Conditions
People with AS may develop additional complications or related conditions, such as:
- Eye inflammation (uveitis): One of the most common complications, causing rapid-onset eye pain, sensitivity to light, and blurred vision.
- Compression fractures: Weakened vertebrae due to early-stage AS can crumple, increasing the severity of a stooped posture and potentially injuring the spinal cord and nerves.
- Heart problems: AS can cause problems with the aorta, the largest artery in the body, leading to an enlarged and distorted aortic valve, impairing its function and increasing the risk of heart disease.
- Psoriasis: A skin condition causing flaky patches of skin.
- Inflammatory bowel disease (IBD): Including Crohn’s disease and ulcerative colitis.
While there is no cure for AS, various treatment options can help manage symptoms, control inflammation, improve posture, and slow the progression of the disease. These may include exercise, physical therapy, occupational therapy, and medications.
Recognizing the Symptoms
The symptoms of ankylosing spondylitis (AS) can vary from person to person and may develop gradually over time. Early signs of AS often include pain and stiffness in the lower back, hips, and buttocks that persists for more than three months. This pain is typically worse in the morning or after periods of inactivity and may improve with exercise or a warm shower.
As the disease progresses, other symptoms may emerge, such as:
- Neck pain and fatigue
- Ligament and tendon pain where these structures attach to the bones
- Loss of appetite and weight loss
- Mild fever and general discomfort
In advanced stages of AS, the inflammation can lead to the formation of new bone, causing the vertebrae to fuse together. This can result in a hunched posture and reduced mobility. The fusion may also affect the rib cage, making it difficult to take deep breaths.
Complications associated with AS can involve various parts of the body, including:
- Eyes: Uveitis, a rapid-onset eye inflammation causing pain, sensitivity to light, and blurred vision
- Joints: Inflammation in the hips, knees, ankles, and shoulders
- Digestive system: Inflammatory bowel disease (IBD) such as Crohn’s disease or ulcerative colitis
- Skin: Psoriasis, causing flaky patches of skin
- Heart: Inflammation of the aorta and aortic valve, increasing the risk of heart disease
It is essential to consult a healthcare provider if you experience persistent back pain or any other symptoms associated with AS. Early diagnosis and treatment can help manage symptoms and slow the progression of the disease.
Diagnosis and Testing
Diagnosing ankylosing spondylitis can be challenging as the condition develops slowly, and there is no definitive test. The first step is to consult a healthcare provider, who will ask about symptoms, including their onset, duration, and characteristics. Back pain associated with ankylosing spondylitis is quite distinctive, as it usually does not improve with rest and may wake the patient during the night.
The physical examination is comprehensive, including a thorough clinical examination of the sacroiliac joints, assessment of spinal mobility, chest expansion, and range of motion of the hip and shoulder joints. The healthcare provider will also look for signs of enthesitis, peripheral arthritis, and associated conditions such as psoriasis or inflammatory bowel disease.

Imaging Tests
X-rays and MRI scans are essential tools in diagnosing ankylosing spondylitis. X-rays can show joint changes, but the visible signs might not be evident in the early stages of the disease. MRI scans can reveal evidence of nonradiographic axial spondyloarthritis earlier in the disease process, providing more detailed images of bones and soft tissues.
Blood Tests
While there are no specific lab tests to identify ankylosing spondylitis, blood tests can check for markers of inflammation. The HLA-B27 gene can also be tested, but its presence alone does not confirm the diagnosis, as many people with the gene do not develop ankylosing spondylitis.
Confirming a diagnosis of ankylosing spondylitis or non-radiographic axial spondyloarthritis often involves a combination of clinical findings, imaging results, and blood tests. Early diagnosis and treatment are crucial for managing symptoms and preventing complications associated with this progressive condition.
Treatment Options
The treatment options for ankylosing spondylitis (AS) focus on managing symptoms, controlling inflammation, improving posture, and slowing the progression of the disease. These may include medications, physical therapy, and in rare cases, surgery.
Medications
Nonsteroidal anti-inflammatory drugs (NSAIDs) are often the first line of treatment for AS. They help reduce pain and inflammation by blocking the production of prostaglandins. Common NSAIDs include ibuprofen, naproxen. If NSAIDs are not effective, disease-modifying antirheumatic drugs (DMARDs) may be prescribed to limit tissue damage from inflammation.
Corticosteroid injections can provide targeted relief for specific joints, but their use is limited due to potential side effects. Biologic medications, such as TNF inhibitors and interleukin inhibitors (ixekizumab), may be used when other treatments are ineffective. These drugs help block proteins responsible for inflammation but can increase the risk of infections and other side effects.
Physical Therapy
Physical therapy plays a crucial role in managing AS symptoms and maintaining physical function. A physical therapist will create an individualized exercise plan that focuses on improving strength, flexibility, posture, and overall physical conditioning. Exercises may include:
- Posture training
- Strengthening exercises
- Flexibility and stretching exercises
- Deep breathing exercises
Physical therapists may also recommend low-impact aerobic exercises such as cycling, swimming, or water aerobics to improve cardiovascular health and manage pain.

Surgery
Surgery for AS is rare and only considered when the condition is severe, and other treatments have not provided sufficient relief. The most common surgical procedures for AS include:
- Laminectomy: Removes the lamina to relieve pressure on nerve roots and reduce pain from compressed nerves.
- Osteotomy: Removes bone and realigns the spine to correct posture and reduce pain in cases of severe spinal curvature.
- Spinal fusion: Stabilizes the spine using rods, bars, or wires to promote healing after a laminectomy or osteotomy.
- Hip replacement: Replaces damaged hip joints with artificial components to restore mobility and reduce pain.
While these surgical options can provide relief, they also carry risks such as infection, blood clots, and nerve damage. Proper preparation and post-operative care are essential for a successful recovery.
