What is indicated by the abbreviation FB in medical terminology?

In medical terminology, the abbreviation FB commonly stands for "Foreign Body." This term is frequently used in clinical settings to describe an object that is not naturally a part of the body and has inadvertently entered it, whether through ingestion, aspiration, or penetrating trauma. Identifying a foreign body is crucial for diagnosis and treatment planning, as it often requires specific interventions such as removal or management to prevent complications.

Understanding this abbreviation is particularly important in emergency medicine, radiology, and outpatient settings where foreign body incidents may be encountered frequently. In contrast, the other options—while they may have relevance in certain medical contexts—do not align with the widely accepted use of the abbreviation FB in the same way.
