Smartphone use on the toilet and the risk of hemorrhoids

★ ★ ★ ☆ ☆

Paper Summary

Paperzilla title
Does doomscrolling cause hemorrhoids? A small study suggests a link.

This cross-sectional study suggests a correlation between prolonged smartphone use on the toilet and an increased prevalence of hemorrhoids. Smartphone users in the study spent more time on the toilet and were younger than non-users. The small sample size, cross-sectional design (correlation, not causation), and self-reported data limit the strength of the conclusions.

Explain Like I'm Five

Using your phone on the toilet for too long might increase your risk of hemorrhoids. Sitting on the toilet for a long time, especially while distracted by your phone, could lead to increased pressure and swelling.

Possible Conflicts of Interest

None identified

Identified Limitations

Small Sample Size
With only 125 participants, the study's power to detect true effects and generalize findings is limited.
Cross-Sectional Design
The study design can only show correlation, not causation. It's impossible to determine whether smartphone use causes hemorrhoids, or if other factors are at play.
Self-Reported Data
Relying on participant recall for time spent on the toilet and straining is prone to bias and inaccuracies.
Confounding Variables
Other lifestyle factors like diet, exercise, and overall health could influence both smartphone use and hemorrhoid development, but were not fully explored.
Limited Generalizability
The study population (adults over 45 undergoing colonoscopies) isn't representative of the general population, limiting the generalizability of the results.

Rating Explanation

The study's methodology has several limitations, including the small sample size, cross-sectional design, and self-reported data. These factors significantly restrict causal inference and generalizability. However, the findings are interesting and provide a basis for further investigation, warranting a rating of 3.
