Habit of Scrolling on the Toilet May Raise Hemorrhoid Risk, New Study Finds

Many people are guilty of using their smartphones while sitting on the toilet. However, a recent study conducted in the United States and published in 2025 indicates that this common habit could significantly elevate the risk of developing hemorrhoids, by up to 46%. The research highlights the link between prolonged toilet sitting, especially time spent looking at a smartphone, and the occurrence of hemorrhoids.

Hemorrhoids, or piles, are cushions of blood vessels and tissue located near the anal opening. They play a crucial role in maintaining bowel control but can become swollen or inflamed, causing pain, bleeding, or lumps, either inside the anus (internal hemorrhoids) or protruding outside (external hemorrhoids). Over half the population will experience hemorrhoids at some stage, and risk factors include age over 45, pregnancy, obesity, persistent constipation or diarrhea, heavy lifting, and spending excessive time on the toilet.

The study examined 125 adults over 45 undergoing colonoscopy at Beth Israel Deaconess Medical Center. Participants reported their smartphone usage during toilet time, including frequency and duration, alongside other behaviors like straining, fiber intake, and physical activity levels. Notably, 66% of participants used their smartphones while on the toilet, primarily to read news or browse social media. These individuals tended to spend more than five minutes on the toilet, with smartphone users spending significantly longer than non-users.

Results revealed that those who used smartphones had a 46% higher risk of developing hemorrhoids after accounting for other known risk factors. Interestingly, the study did not find a direct association between straining and hemorrhoids, suggesting that extended time on the toilet—especially with distractions—might be more influential. However, the study's limitations include reliance on self-reported data, which may be subjective, and a small, age-specific sample, which might not reflect the broader population.

Previous research from 2020 supports these findings, indicating that spending over five minutes on the toilet correlates with hemorrhoid development and severity. Typical defecation times are short—around two minutes for healthy adults—so extended toilet sitting, often spent reading or using devices, increases internal pressure in the pelvic region, contributing to hemorrhoid formation.

Experts recommend increasing fiber intake and staying well-hydrated to promote easier bowel movements and reduce straining. Importantly, reducing toilet sitting time by avoiding distractions like smartphones can help lower hemorrhoid risk. If symptoms such as blood in stools, anal lumps, or pain occur, consulting a healthcare professional is advised.
