Using Smartphones on the Toilet Linked to Increased Hemorrhoid Risk, New Study Finds

A recent study presented at Digestive Diseases Week (DDW) 2025 has revealed a surprising connection between smartphone use on the toilet and an increased risk of hemorrhoids. According to research conducted by Dr. Trisha Satya Pasricha and colleagues at Beth Israel Deaconess Medical Center in Boston, adults who use smartphones while on the toilet spend significantly more time seated and have a 46% higher likelihood of developing hemorrhoids compared to those who do not engage in this habit.

Study Overview and Key Findings

The cross-sectional survey involved 125 adult patients undergoing screening colonoscopy. Researchers assessed participants’ smartphone habits during toilet use, gastrointestinal symptoms, and lifestyle factors such as fiber intake and physical activity. Hemorrhoids were directly visualized and documented during colonoscopy.

• Prevalence of Hemorrhoids: 43% of participants had hemorrhoids visible on colonoscopy.

• Smartphone Usage: 66% of respondents reported using smartphones on the toilet, with 93% of these users engaging in this behavior at least once or twice weekly.

• Time Spent on Toilet: Smartphone users were more likely to spend extended time on the toilet; 37.3% spent over 6 minutes per visit compared to only 7.1% of non-users.

• Increased Risk: After adjusting for age, sex, BMI, exercise, and fiber intake, smartphone use on the toilet was associated with a 46% increased risk of hemorrhoids (P = .044).

• Common Activities: Reading news (54.3%), social media browsing (44.4%), and emailing or texting (30.5%) were the most frequent activities performed on smartphones during toilet visits.

Implications and Recommendations

The study authors suggest that prolonged sitting and distraction caused by smartphone use may contribute to increased pressure on the rectal veins, potentially leading to hemorrhoid development. While the findings do not establish a direct cause-and-effect relationship, they highlight the importance of mindful bathroom habits.

Dr. Pasricha stated, “Prolonged engagement with smartphones while using the toilet may be associated with an increased prevalence of hemorrhoids. Further research is warranted to explore causal relationships and examine behavioral modifications as strategies for preventing hemorrhoid development.”

What This Means for You

• Limit time spent on the toilet, especially when using smartphones.

• Avoid straining during bowel movements.

• Maintain a high-fiber diet and stay physically active to promote healthy digestion.

• Consider reducing smartphone use in the bathroom to minimize potential risks.
