Ankylosing spondylitis is an inflammatory disease that, over time, can cause some of the vertebrae in your spine to fuse. This fusing makes the spine less flexible and can result in a hunched-forward posture. If ribs are affected, it can be difficult to breathe deeply. Ankylosing spondylitis affects men more often than women. Ankylosing Spondylitis Symptoms typically begin in early adulthood. Inflammation also can occur in other parts of your body — most commonly, your eyes. There is no cure for ankylosing spondylitis, but treatments can lessen your Ankylosing Spondylitis Symptoms and possibly slow progression of the disease.
Early signs and symptoms of ankylosing spondylitis might include pain and stiffness in your lower back and hips, especially in the morning and after periods of inactivity. Neck pain and fatigue also are common. Over time, symptoms might worsen, improve or stop at irregular intervals.
