Ankylosing Spondylitis (AS) is a type of progressive arthritis that leads to chronic inflammation of the spine and sacroiliac joints. It can also affect other joints and organs in the body, such as the eyes, lungs, kidneys, shoulders, knees, hips, heart, and ankles.
Ankylosing spondylitis is an arthritic condition that causes inflammation along the spine. If left untreated, the condition can cause the vertebrae to fuse together. When the vertebrae fuse, a personâs posture becomes hunched forward. Depending on the severity of these complications, crowding in the ribs can make it difficult for a person with ankylosing spondylitis to breathe. Inflammation is not always limited to the spine. Some people who have ankylosing spondylitis also experience inflammation around the eyes. The condition most commonly affects men, and symptoms are first noticed in early adulthood.
