Question: What is (are) Diffuse idiopathic skeletal hyperostosis ?
Answer: Diffuse idiopathic skeletal hyperostosis (DISH) is a form of degenerative arthritis in which the ligaments (connective tissues that connect bones) around the spine turn into bone. Many people with this condition do not experience any symptoms. When present, the most common features are pain and stiffness of the upper back; however, other symptoms may also develop when bone spurs press on nearby organs or parts of the body. The exact underlying cause of DISH remains unknown, although risk factors such as age, gender, long-term use of certain medications and chronic health conditions have been identified. Treatment for DISH depends on many factors including the signs and symptoms present in each person and the severity of the condition.
