Impact of the Four Seasons on Bowel Cleansing Quality Prior to Colonoscopy

Patients scheduled to undergo elective colonoscopy will be evaluated in this observational study. No additional medications, interventions, or diagnostic procedures beyond standard clinical practice will be administered. The primary objective of the study is to investigate whether the quality of bowel preparation prior to colonoscopy varies according to seasonal differences. Bowel cleansing quality will be assessed during the colonoscopy procedure using standard evaluation criteria. The quality of bowel preparation will be compared across different seasons to determine the potential impact of seasonal variation on bowel cleansing adequacy prior to elective colonoscopy.
