Which symptom describes a constant urge to pass stool without relief?

The correct answer is tenesmus, which refers to the sensation of constantly needing to pass stool, even if the bowel is empty or only a small amount is passed. This condition is often accompanied by discomfort and may also involve cramping, straining, and an inability to relieve the urge to defecate. It is commonly seen in gastrointestinal disorders such as inflammatory bowel disease or infections affecting the rectum and anus.

Understanding tenesmus is important in clinical practice, as it can help healthcare providers assess underlying issues and develop appropriate treatment plans. Recognizing this symptom can prompt further evaluation for conditions that require intervention, such as proctitis or other forms of colitis.
