Clinical Information about Ankylosing Spondylitis:

Ankylosing Spondylitis is a type of arthritis characterized by chronic spine inflammation. This condition causes the sacroiliac joints and the vertebrae to become inflamed, which leads to persistent back and hip pain, including stiffness. This makes the person feel pain whether they’re immobile or moving their backs, but they will also have difficulty moving.

Over time, the vertebrae may fuse due to new bone formations, which can further affect the spine, resulting in a stooped posture and even lessening the spine's flexibility.

Besides back pain, hip pain, and stiffness, people who have Ankylosing Spondylitis will likely have the following symptoms:

• Neck pain
• Joint pain
• Abdominal pain
• Weakness and fatigue
• Difficulty breathing
• Loss of appetite
• Weight loss
• Diarrhea
