5. A cause of constipation is:

Answer: C

Explanation:

Certain medications are a cause of constipation.

Constipation can be caused by certain medications that affect bowel movements. These medications may slow down intestinal motility or alter the normal function of the digestive system.

A) Increased fluids

Increased fluid intake generally helps to alleviate constipation by softening the stool and promoting regular bowel movements. Therefore, this option is incorrect as it is typically associated with preventing rather than causing constipation.

B) High-fiber diet

A high-fiber diet is known to enhance digestive health and prevent constipation by adding bulk to the stool and facilitating its passage through the intestines. Hence, this option is also incorrect as it promotes bowel regularity rather than causing constipation.

C) Certain medications

Certain medications, such as opioids, antacids containing aluminum, and some antidepressants, can lead to constipation as a side effect. This option accurately identifies a common cause of constipation, making it the correct answer.

D) Increased activity

Increased physical activity is associated with improved bowel function and can help prevent constipation. Therefore, this option is incorrect since it typically encourages regularity rather than contributing to constipation.

Conclusion

The identification of certain medications as a cause of constipation is crucial, as they can significantly impede normal bowel function. In contrast, all other options—increased fluids, a high-fiber diet, and increased activity—are linked to preventing constipation. Understanding these distinctions is essential for effective management of bowel health.
