Ankylosing spondylitis can briefly be summaries as under:
1. Ankylosing spondylitis belongs to a group of arthritis conditions which tend to cause chronic inflammation of the spine as well as degeneration.
2. Ankylosing spondylitis is a cause of back pain in adolescents and young adults.
3. Tendency to develop Ankylosing spondylitis is genetically inherited.
4. The HLA-B27 gene can be detected in the blood of most patients with AS.
5. Ankylosing spondylitis can also affect eyes, heart, lungs, and occasionally the kidneys
6. The optimal treatment of Ankylosing spondylitis involves medications that reduce inflammation or suppress immunity, physical therapy and exercise.
7. Homeopathy offers encouraging results, significant disease control and pain relief.
 

Site of disease:
The sacroiliac joints are located in the low back where the sacrum (the bone directly above the tailbone) meets the iliac bones (bones on either side of the upper buttocks). Due to chronic inflammation in these areas there are symptoms like pain and stiffness of spine. As this condition is chronic one with time this leads to fusion of the vertebrae i.e. complete cementing together of vertebrae.

This process is known as Ankylosis. Due to this condition there is loss of mobility if
spine. The stiffness could eventually be very severe making the spine resembling a bamboo. Hence it is also called bamboo spine.

Ankylosing spondylitis can affect other tissues throughout the body. It can cause inflammation in or injury to other joints away from the spine, as well as other organs, such as the eyes, heart, lungs, and kidneys.
 

Related conditions:
1. Psoriatic Arthritis
2. Reactive Arthritis
3. Arthritis associated with Crohn’s disease and ulcerative colitis.
These conditions are collectively referred to as "spondyloarthropathies."
 

Prevalence of AS:
Ankylosing spondylitis is two to three times more common in males than in females.

In women, joints away from the spine are more frequently affected than in men.
Ankylosing spondylitis affects all age groups, including children. The most common
age of onset of symptoms is in the second and third decades of life. One research study says that male to female ratio of this disease condition is 4:1.
