Ankylosing spondylitis (AS) is a chronic inflammatory disorder of the spine and sacroiliac joints that can cause pain and stiffness in the lower back and hips. It is a type of arthritis that primarily affects the spine, but can also affect other joints and organs.
The exact cause of AS is unknown, but it is believed to be a combination of genetic and environmental factors. Some research suggests that the condition may be an autoimmune disorder, in which the body’s immune system mistakenly attacks healthy tissues. Other studies suggest that it may be an autoinflammatory disorder, in which the body’s immune system inappropriately activates and causes inflammation.
The symptoms of AS can vary from mild to severe, and can be managed with medications, physical therapy, and lifestyle changes. People with AS may experience fatigue, stiffness, and pain in the lower back and hips. It can also cause changes in posture, such as a stooped or hunched back, and can lead to fusion of the vertebrae in the spine.
Currently, there is no cure for AS. However, medications, physical therapy, and lifestyle changes can help manage symptoms and reduce the risk of complications.
In conclusion, the exact cause of AS is unknown, but it is believed to be a combination of genetic and environmental factors. Some research suggests that it may be an autoimmune disorder, while other studies suggest it may be an autoinflammatory disorder. Treatment is aimed at managing the symptoms and reducing the risk of complications.
