List of Medical Abbreviations (A to Z)
Medical abbreviations are commonly used in the English language to shorten long phrases and words. While there are many medical abbreviations, some of the more common ones include AIDS, ADHD, and OCD. By using medical abbreviations, doctors are able to communicate more effectively with one another, as well as with their patients. In addition, medical abbreviations can help to save time during a doctor’s visit.
