Which gastrointestinal problem caused by chemotherapy occurs because of autonomic nervous system dysfunction?

• A. Constipation
• B. Diarrhea
• C. Nausea
• D. Vomiting

Answer: (A)

Chemotherapy can cause autonomic neuropathy that disrupts the nerves coordinating intestinal movement. When autonomic input to the gut is diminished, peristalsis slows, so stool moves slowly through the colon and constipation develops. Nausea and vomiting are driven largely by central reflex centers and chemoreceptor triggers, while diarrhea stems mainly from mucosal injury and secretory changes—so they’re less about autonomic dysfunction. This is why constipation best fits the scenario.
