Which lifestyle modification helps manage anticholinergic side effects?

• A. Increase protein intake
• B. Increase fiber and fluids
• C. Decrease fluid intake
• D. Avoid exercise

Answer: (B)

Managing anticholinergic side effects is about countering dryness and slowed gut movement. Medications with anticholinergic effects reduce acetylcholine signaling, which can lead to dry mouth and constipation. Increasing fiber intake adds bulk to the stool and speeds its passage through the colon, while drinking more fluids keeps stool soft and helps maintain mucosal moisture. Together, more fiber and fluids directly address the main bothersome issues from these drugs, making bowel movements easier and reducing dryness. Increasing protein won’t alleviate constipation or dry mouth, decreasing fluids would worsen dryness and constipation, and avoiding exercise doesn’t help with these specific GI and hydration issues.
