Ankylosing spondylitis (AS) is a form of arthritis that causes inflammation in the joints and ligaments of the spine, resulting in pain and stiffness. The disease can also affect peripheral joints like the knees, ankles, and hips, and may cause damage to the eyes, heart, lungs, and intestinal tract. The most common symptom of AS is lower back and/or hip pain, which worsens during periods of rest or inactivity. While the exact cause of AS is unknown, studies show that both genes and environmental factors may play a role in its development. Treatment options include medication, physiotherapy, acupuncture, and exercise, which can help improve pain and stiffness, as well as slow disease progression.

Ankylosing spondylitis causes inflammation in the spine and joints, resulting in pain and stiffness
Ankylosing spondylitis (AS) is a form of arthritis that causes inflammation in the joints and ligaments of the spine. This inflammation can result in pain and stiffness, particularly in the lower back and hips. The condition typically worsens during periods of rest or inactivity, causing increased pain during the night or after prolonged inactivity. Moving and exercise can help alleviate these symptoms.
AS is a chronic inflammatory disease that primarily affects the spine, although it can also impact peripheral joints such as the knees, ankles, and hips. The inflammation associated with AS can lead to the fusion of vertebrae, resulting in a rigid and inflexible spine. This fusing of bones can cause a hunched or stooped posture and may affect an individual's ability to breathe deeply if the ribs are involved.
The exact cause of AS is unknown, but researchers believe that both genetic and environmental factors play a role. The HLA-B27 gene has been identified as a risk factor, although not everyone with this gene will develop AS. Symptoms of AS vary from person to person and can include mild to severe pain, stiffness, and inflammation in the joints. Other symptoms may include digestive issues, rashes, weight loss, and eye inflammation (uveitis).
Treatment for AS focuses on reducing inflammation, easing pain, and slowing disease progression. Nonsteroidal anti-inflammatory drugs (NSAIDs), biologics, and corticosteroids are commonly used to manage inflammation and pain. Physiotherapy and exercise play a crucial role in improving muscle strength, maintaining mobility, and preventing stiffness. Maintaining good posture and staying active are also important components of AS management.
While there is no cure for AS, early treatment and lifestyle changes can help improve quality of life and prevent permanent joint damage. It is important for individuals experiencing symptoms of AS to seek medical attention, as a timely diagnosis can lead to more effective management of the condition.

The disease can cause bones to fuse, restricting movement and causing further pain
Ankylosing spondylitis (AS) is a form of arthritis that causes inflammation in the joints and ligaments of the spine. This inflammation can cause back pain and stiffness, particularly in the lower back and hips. Over time, the symptoms may progress to other areas of the spine or body. The pain typically worsens during periods of rest or inactivity.
AS can cause new bone to form in the spine, leading to a condition known as ankylosing spondylitis. This occurs when the vertebrae fuse together, resulting in a rigid and inflexible spine. The fused vertebrae can flatten the natural curves of the spine, causing an inflexible, hunched posture. This can make it difficult to bend and move, restricting movement and causing further pain.
The disease may also affect the ribs, making it difficult to breathe deeply. In some cases, bones in the chest may fuse, further impacting breathing. AS can also cause osteoporosis, or thinning of the bones, which can result in spinal fractures.
Treatment for AS aims to reduce inflammation, ease pain, and slow disease progression. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), biologic disease-modifying anti-rheumatic drugs (DMARDs), and corticosteroids can be used to manage inflammation and pain. Physiotherapy and exercise are also important components of treatment, helping to improve muscle strength, maintain mobility, and prevent stiffness. Maintaining good posture and staying active can also help to reduce pain and improve quality of life.

Ankylosing spondylitis can lead to osteoporosis, increasing the risk of spinal fractures
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease that primarily affects the sacroiliac joints, vertebrae, and intervertebral discs. It is a type of arthritis that causes stiff and painful joints in the spine, usually in the lower back. The inflammation associated with AS can lead to bone erosion and new bone formation, resulting in a loss of mobility and a hunched posture.
AS is associated with an increased risk of osteoporosis, even in the early stages of the disease. Osteoporosis is a condition characterized by low bone mineral density (BMD) and bone loss, which can weaken the bones and make them more susceptible to fractures. In the context of AS, osteoporosis can further compromise the structural integrity of the spine, increasing the risk of spinal fractures.
The development of osteoporosis in AS is influenced by various factors, including elevated levels of biochemical markers of bone turnover, pro-inflammatory cytokines, and acute-phase reactants. Systemic inflammatory mediators such as interleukin-6 and tumor necrosis factor-alpha may play a role in bone loss. Additionally, genetic factors, vitamin D deficiencies, low levels of sex steroid hormones, and impaired calcium absorption can contribute to osteoporosis in individuals with AS.
The presence of osteoporosis can complicate the management of AS. Diagnosing spinal osteoporosis in AS patients can be challenging due to the formation of new bone tissue, which interferes with accurate assessments of bone mineral density. Advanced imaging techniques, such as multidetector CT and MRI scans, may be employed to confirm the presence of fractures and guide treatment decisions.
The treatment options for AS-related osteoporosis and spinal fractures depend on the patient's overall health, age, and fracture stability. Both non-operative and operative treatments are available, including external orthoses, traction, halo vest placement, and surgical interventions. Early diagnosis and appropriate management are crucial to prevent further complications and potential neurological injuries associated with spinal fractures.

Inflammation can spread to other parts of the body, causing organ damage and digestive issues
Ankylosing spondylitis (AS) is a form of arthritis that causes inflammation in the joints and ligaments of the spine. It is also referred to as axial spondyloarthritis. The inflammation associated with AS can spread to other parts of the body, causing a range of issues.
AS can cause organ damage, particularly to the heart, lungs, and eyes. In terms of the heart, AS can cause problems with the aorta, the largest artery in the body. The inflamed aorta can enlarge, distorting the shape of the aortic valve and impairing its function. This increases the risk of heart disease. Eye inflammation, or uveitis, is a common complication of AS, causing eye pain, light sensitivity, and blurred vision.
AS can also lead to digestive issues. Abdominal pain and loose bowel movements are symptoms that may occur. In some cases, AS can cause intestinal inflammation, resulting in conditions such as Crohn's or ulcerative colitis.
The treatment for AS focuses on reducing inflammation, easing pain, and slowing disease progression. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), biologic disease-modifying anti-rheumatic drugs (DMARDs), and corticosteroids are used to manage inflammation and pain. Physiotherapy and exercise play a crucial role in improving muscle strength, maintaining mobility, and reducing stiffness.
It is important to note that AS can vary in severity and progression, and early diagnosis and treatment are essential to prevent permanent damage to joints and improve quality of life.

Ankylosing spondylitis (AS) is a type of arthritis that causes stiff, painful joints in the spine, usually in the lower back. It is an inflammatory disease that can cause vertebrae in the spine to fuse over time, resulting in a loss of flexibility and a hunched posture. While there is no cure for AS, treatments can help relieve symptoms, slow or prevent disease progression, and delay or prevent spinal fusion.
Treatments include medication, physiotherapy, and lifestyle changes to:
- Relieve pain and stiffness: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are commonly used to treat pain and inflammation. If NSAIDs are ineffective, doctors may suggest tumour necrosis factor (TNF) blockers, interleukin-17 (IL-17) inhibitors, or steroid injections.
- Improve strength and flexibility: Physiotherapy is crucial for improving muscle strength and maintaining mobility in the spine and joints. Physiotherapists can design specific exercise programs to meet individual needs, including range-of-motion exercises, strengthening exercises, and guidance on proper sleeping and walking positions.
- Maintain a healthy weight: Keeping a healthy weight is important to reduce stress on painful joints.
- Quit smoking: Smoking can worsen ankylosing spondylitis, further compromising lung function and blunting the effects of treatment.
- Exercise: Regular physical activity can reduce stiffness and prevent AS from worsening. Low-impact exercises, such as water exercise programs, are recommended to maintain healthy and strong muscles, preserve joint mobility, and maintain flexibility.
- Improve posture: Practicing good posture, such as standing straight, can help avoid problems associated with ankylosing spondylitis.
- Manage the disease: Self-care and education about the disease and its treatments can empower individuals to manage their condition and improve their health. This includes communicating with the healthcare team, seeking support for physical and mental health, and participating in care decisions to build confidence in performing daily activities.
- Address eye inflammation: Eye inflammation (uveitis) is a common complication of ankylosing spondylitis. It is typically treated with steroid eye drops, but more severe cases may require steroid tablets or injections.
