Doctors and other healthcare professionals abbreviate certain medical terminologies for convenience in completing patient charts, writing prescriptions, communicating needs and billing for services. Medical terminology can be very technical and wordy, so abbreviations help to save time and space, especially in writing.
Some medical abbreviations include AKA, a.c., COPD, EBL, Fx, STD and WA. These mean "above the knee amputation," "before meals," "chronic obstructive pulmonary disease," "estimated blood loss," "fracture," "sexually transmitted disease," and "while awake," respectively.
In medical terminology, the capitalization in abbreviations is significant for determining the meaning of certain words and differentiating certain abbreviations from similar acronyms.
