Ankylosing spondylitis is an autoimmune disease that cannot be cured. It can only be managed with medication to control the condition, delay the onset of joint deformities, and reduce the rate of disability. Lifestyle changes are also a part of the treatment, including quitting smoking and drinking, and avoiding carbonated beverages as they can exacerbate bone loss. Additionally, regular exercise is important, with swimming being the best option. Swimming not only exercises the limbs and improves muscle coordination but also reduces joint wear and tear, making it the ideal form of exercise. For patients who cannot swim, other forms of exercise such as walking or running are also beneficial for fitness.
