<\/p>\n
Ankylosing spondylitis is a chronic inflammatory condition that primarily affects the spine and sacroiliac joints. These are the joints connecting the base of the spine to the pelvis. Over time, persistent inflammation leads to pain, stiffness, and in severe cases, fusion of vertebrae.<\/p>\n
<\/p>\n
Spondyloarthritis, the broader disease family to which ankylosing spondylitis belongs, is the second most common inflammatory rheumatic disease in India after rheumatoid arthritis, according to research mentioned in The Times of India. Early ankylosing spondylitis symptoms often resemble ordinary back pain, leading to delayed diagnosis.<\/p>\n
<\/p>\n
This article explains ankylosing spondylitis meaning, its causes, symptoms, and how it is diagnosed.<\/p>\n
Ankylosing spondylitis’s meaning is best understood through its name: ‘ankylosing’, which means stiffening or fusion of joints, ‘spondyl’ refers to the vertebrae, and ‘itis’ means inflammation. Together, the term describes a condition that inflames and progressively stiffens the joints of the spine.<\/p>\n
The exact ankylosing spondylitis causes are not fully known, but genetics play an important role. The HLA-B27 gene is the most established risk factor. Over 90% of patients with ankylosing spondylitis carry the HLA-B27 antigen.<\/p>\n
<\/p>\n
Other risk factors include:<\/p>\n
<\/p>\n
Ankylosing spondylitis symptoms develop gradually. The most common early sign is persistent, dull lower back and buttock pain, typically worse in the morning or after rest, and improving with movement.<\/p>\n
<\/p>\n
Common symptoms include:<\/p>\n
<\/p>\n
<\/p>\n
Without management, ongoing inflammation can cause the vertebrae to fuse, leading to a rigid, stooped posture.<\/p>\n
Diagnosing ankylosing spondylitis requires clinical assessment, imaging, and laboratory tests. A rheumatologist is typically involved, given the overlap of ankylosing spondylitis symptoms with other spinal conditions.<\/p>\n
<\/p>\n
Key diagnostic steps include:<\/p>\n
<\/p>\n
<\/p>\n
A positive HLA-B27 blood test alone does not confirm ankylosing spondylitis. Results must be interpreted alongside symptoms and imaging.<\/p>\n
There is no cure for ankylosing spondylitis, but early diagnosis and appropriate management help control pain and slow progression. The goals of ankylosing spondylitis treatment are to reduce stiffness, preserve spinal mobility, and prevent complications.<\/p>\n
<\/p>\n
Common management steps include:<\/p>\n
<\/p>\n

Individuals with persistent lower back pain that worsens with rest but improves with movement, especially those under 40, should seek medical evaluation and book the HLA-B27 Qualitative PCR test<\/a> with Dr. Lal PathLabs.

It belongs to a group of diseases called spondyloarthritis.<\/p>\n A positive HLA B27 test indicates the presence of the HLA-B27 antigen, strongly linked to ankylosing spondylitis. However, not everyone who tests positive develops the disease, so results must be interpreted alongside clinical symptoms and imaging.<\/p>\n Ankylosing spondylitis most commonly begins in people between below the age 40.<\/p>\n","protected":false},"excerpt":{"rendered":" Ankylosing spondylitis is a chronic inflammatory condition that primarily affects the spine and sacroiliac joints.
