Patient's question:
Recently, I heard from my friend that their elderly father has been diagnosed with ankylosing spondylitis. I don't know what this disease is, what are the main causes of this condition, and what age groups are most affected. So, here I would like to know what ankylosing spondylitis is?Doctor's answer:
The cause of ankylosing spondylitis is not clear, and there is no definitive conclusion in medicine regarding what causes this disease. It is generally believed to be caused by intergenerational genetic factors and living environment. The onset age of patients is mainly concentrated between 15 and 30 years old, with adolescents being more common. Patients may experience lower back pain, and further progression may lead to symptoms of overall stiffness.
