Human Illnesses and Problems Acronyms

List of acronyms, abbreviations, and initials that relate to human diseases and includes both infectious and non-infectious diseases and medical disorders..

Periods (full stops) were often used when styling abbreviations, however, prevalent practice in medicine today is often to forego them as unnecessary.

A common way to represent plurals when writing medical acronyms, abbreviations, and initials is to add a lowercase “s” without an apostrophe.

While the vast majority of people don’t really need to understand specific discipline terminology outside of their profession, medical vocabulary is one notable exception in order to know about factors regarding our health.

A list of medical abbreviations and acronyms of the most common infectious and non-infectious human Diseases and disorders. Periods (full stops) were often used when styling abbreviations, however, prevalent practice in medicine today is often to forego them as unnecessary. In addition the most common way to represent plurals when writing medical acronyms, abbreviations, and initials is to add a lowercase “s” – without an apostrophe.

Whether you are working on mastering medical abbreviations or just looking to research a specific acronym, feel free to consult our free comprehensive guide to acronyms, abbreviations, and initials used in hospitals.
