What does "guarding" refer to in the context of a physical exam?

Guarding refers to a protective mechanism that patients exhibit during a physical examination, particularly when assessing the abdomen. When a healthcare provider examines the abdomen and the patient feels discomfort or experiences pain, they may instinctively tense their abdominal muscles or withdraw from contact, which is known as guarding. This reaction helps to protect the area from further discomfort or injury and is often indicative of underlying issues, such as inflammation or irritation within the abdominal organs.

In clinical practice, observing guarding can prompt further evaluation and investigation to determine any potential abdominal conditions that may require treatment. This physiological response serves as an important diagnostic cue for healthcare providers during a physical examination.
