Overview
- The PLOS One analysis surveyed 125 adults undergoing colonoscopy at Beth Israel Deaconess, allowing doctors to directly confirm hemorrhoids during the procedure.
- Participants who reported using smartphones on the toilet were 46% more likely to have hemorrhoids even after adjusting for age, sex, BMI, exercise, straining, and fiber intake.
- About 37% of smartphone users sat longer than five minutes per bathroom visit compared with 7% of non-users, suggesting phones prolong toilet time.
- Clinicians advise leaving phones outside the bathroom, limiting toilet sitting to a few minutes, improving fiber intake and hydration, and note that posture aids reduce straining but do not offset prolonged sitting.
- Authors caution the findings are observational and based on a small, older sample with self-reported habits, and they call for larger, prospective studies; hemorrhoids drive nearly 4 million U.S. clinic and ER visits annually.
