Spondylitis is mostly caused by a combination of genetic, infectious and degenerative factors, and is a general term for a large group of diseases. 1. Infectious spondylitis: caused by bacterial infection, autoimmune disease or repeated unbalanced spinal force and other factors, such as staphylococcus aureus and other causes of spondylitis and inflammation of the fascia caused by strenuous exercise. 2. Degenerative spondylitis: joint metabolic disorders occur after the joints are stimulated by the outside world, or the body’s nutritional deficiencies and other joint injuries caused by the lack of effective treatment, can cause hypertrophic spondylitis, that is, degenerative spondylitis. 3. Autoimmune spondylitis: microorganisms such as Klebsiella and the human body have common antigens, which can trigger their own immune response and cause autoimmune spondylitis. If you are diagnosed with spondylitis, please go to the hospital for systematic treatment and follow the doctor’s instructions, and pay attention to moderate exercise.
