What causes Diffuse idiopathic skeletal hyperostosis ?
What causes diffuse idiopathic skeletal hyperostosis ? The exact underlying cause of diffuse idiopathic skeletal hyperostosis (DISH) is poorly understood. However, several factors have been associated with an increased risk of developing the condition. For example, conditions that disturb cartilage metabolism (such as diabetes mellitus, acromegaly, or certain inherited connective tissue disorders) may lead to DISH. Long-term use of medications called retinoids (such as isotretinoin) can increase the risk for DISH. Age (being older than age 50) and sex (being male) may also play a role.
