What level of abdominal distention would indicate that holding enteral feedings is appropriate?

• A. Holding enteral feedings is generally not indicated unless abdominal girth exceeds the baseline measurement by at least 8 to 10 cm
• B. Abdominal girth >2 cm
• C. Abdominal girth >20 cm
• D. Abdominal girth >15 cm

Answer: (A)

Distention is a sign of potential feeding intolerance, but small fluctuations in abdominal size are common and not cause to stop feeds. The most clinically meaningful trigger to hold enteral nutrition is a substantial increase from the patient’s baseline abdominal girth. When abdominal girth rises by about 8–10 cm above baseline, that change suggests a true intolerance or evolving complication (such as ileus or significant gas/fiberal distention) and warrants pausing feeds to evaluate and manage before continuing.

Understanding this threshold helps balance the goal of providing nutrition with the need to prevent complications like aspiration or worsening distention. If the increase is smaller (for instance, around 2 cm), continued feeding with careful monitoring is typically reasonable, provided there are no other concerning signs (vomiting, high residuals, pain, or worsening distention). Conversely, very large increases (e.g., 15–20 cm) would indicate a high risk and require urgent assessment.

In practice, measure abdominal girth consistently at the same location and time, compare to the established baseline, and integrate other clinical findings to decide on the feeding plan.
