Which of the following is a sign of chronic constipation?

Chronic constipation is characterized by infrequent bowel movements, which is a hallmark sign of the condition. This typically means having fewer than three bowel movements per week. Infrequent bowel movements can lead to difficulties in passing stools, causing discomfort and potential complications like hemorrhoids or fissures. Recognizing this symptom is crucial for diagnosing and managing chronic constipation effectively.

Frequent diarrhea is not a sign of chronic constipation; rather, it indicates a different digestive issue. Unexplained weight gain may occur for several reasons unrelated to bowel habits. Similarly, persistent fatigue can stem from numerous factors, including but not limited to diet, sleep issues, and underlying health conditions—not specifically tied to the function of the gastrointestinal system. Thus, infrequent bowel movements serve as a clear indicator of chronic constipation.
