What is fecal impaction?

Fecal impaction refers specifically to the prolonged retention and buildup of feces in the rectum, which ultimately creates a blockage. This condition occurs when stool becomes hard and dry, often due to chronic constipation or infrequent bowel movements. The pressure of the impacted stool can lead to a variety of complications, including discomfort, pain, and even more serious issues if not addressed.

The characteristic factors of fecal impaction highlight that it is not merely the inability to pass stool completely but rather a specific situation where there is a significant mass of stool that cannot be expelled due to its size or hardness. While other options mention related issues in the digestive system, they do not accurately define fecal impaction, which is specifically about the accumulation and retention of feces in the rectal area.
