No doubt as some point in your life you will have had an “itis” of one form or another e.g. tonsillitis, laryngitis, appendicitis. The suffix “itis” seems to find its way into many medical terms. Have you ever thought about what exactly it means? Often it is assumed that infection is the cause. Whilst that may indeed be the case, “itis” simply means inflammation and doesn’t necessarily mean that there is an infection. Can you think of an example of an “itis” that isn’t infective in origin?
