1. Leave of absence

Business & Finance · Human Resources Abbreviations

Approved extended period away from work while remaining employed, for reasons such as medical treatment, family care, military service, education or personal matters. A leave may be paid or unpaid and may be protected by law or granted under company policy.

Example: He's on LOA until March, so route his accounts to the backup rep.

Legally protected leaves in the US include FMLA leave, military leave under USERRA (up to five years cumulative), and leave as a reasonable accommodation under the ADA. Benefits continuation and job reinstatement rights differ by leave type, so HR tracks each one carefully.

2. Lysis of adhesions

Medical · Surgical Abbreviations

Surgical division of internal scar tissue bands (adhesions) that form after previous operations or inflammation and can cause bowel obstruction, chronic pain or infertility. It can be done laparoscopically or through open surgery.

Example: Laparoscopic LOA for adhesive small bowel obstruction; no bowel resection required.

Adhesions form in most patients after abdominal surgery, but only some cause problems. Many adhesive small bowel obstructions resolve with bowel rest and a nasogastric tube, and water-soluble contrast studies help predict which will. Every operation risks forming new adhesions. In psychiatric and military records LOA means leave of absence.

3. Length overall

Transportation & Travel · Maritime Abbreviations

Maximum length of a vessel from the foremost to the aftmost point of the hull, including fixed bow sprits or overhangs. Marinas, ports and canals charge fees and set limits by LOA.

Example: The marina charges by LOA, so the anchor platform added two feet to our bill.

Naval architects also use length at waterline (LWL) and length between perpendiculars (LBP), which affect speed and tonnage calculations. LOA appears in yacht listings and ship specifications. Port entry rules for large ships often set maximum LOA.
