Which abbreviation is used for Headache?

The abbreviation used for headache is "HA." This shorthand is commonly recognized in medical terminology and is widely used in clinical practice. By using "HA," healthcare providers can efficiently communicate about a patient's symptoms without needing to write out the full term "headache," which helps streamline documentation processes.

The other options do not accurately represent the term for headache in the medical context. "HD" typically stands for "heart disease" or "hemodialysis"; "HEA" is not a standard abbreviation in this context; and "HED" does not correspond to any widely accepted term related to headaches. Utilizing "HA" allows for clear and effective communication among healthcare professionals when discussing headache cases.
