Ankylosing spondylitis (AS) is an inflammatory type of arthritis that primarily affects the spine. It is an autoimmune disorder that causes inflammation of the joints, resulting in pain and stiffness. The red flags for ankylosing spondylitis include:
1. Lower Back Pain: The most common symptom of AS is chronic lower back pain, often accompanied by stiffness and a feeling of tightness in the lower back.
2. Morning Stiffness: People with AS often experience morning stiffness as well as stiffness after periods of inactivity.
3. Posture Problems: Over time, AS can cause changes to your posture, leading to a hunched-over position.
4. Pain and Stiffness in Other Areas: AS can also cause pain and stiffness in other areas of the body, such as the neck, shoulders, hips, and heels.
5. Fatigue: People with AS often experience fatigue, which can be caused by the pain and stiffness of the disorder.
6. Unexplained Weight Loss: Unexplained weight loss is another common symptom of AS, as it can be caused by the inflammation and pain associated with the disorder.
If you experience any of these red flags, it is important to talk to your doctor. Early diagnosis and treatment of AS can help manage the symptoms and reduce the risk of long-term complications.
