People who use smartphones while sitting on the toilet may be at higher risk for hemorrhoids, according to a new study; similar associations are reported in prior research. Most related studies generally support the finding that extended smartphone use in the bathroom can contribute to increased hemorrhoid risk, with additional concerns about hygiene and broader health habits, as documented in recent literature and the open access journal PLOS One.
- Multiple observational studies report a link between prolonged mobile phone use on the toilet and increased prevalence of hemorrhoids, with time spent seated being a key contributing factor 1 2.
- Related research highlights that smartphone use in the bathroom is common across age groups, often accompanied by behaviors that can negatively impact physical health, hygiene, and even increase the risk of bacterial contamination 1 4 5 6.
- While there is consensus on the potential risks, some studies also note gaps in longitudinal evidence and call for further research to confirm causality and explore mechanisms behind these associations 1 2 3.
Study Overview and Key Findings
The increasing ubiquity of smartphones in daily life has prompted questions about their effects on health, especially regarding behaviors that may inadvertently increase health risks. This new study addresses a long-suspected, but rarely investigated, link between smartphone use while sitting on the toilet and the development of hemorrhoids. By directly assessing both self-reported habits and clinical findings among adults undergoing colonoscopy, the research provides new data on this modern lifestyle factor and its potential medical consequences.

In this study, 125 adults undergoing screening colonoscopies at Beth Israel Deaconess Medical Center were surveyed on their bathroom smartphone habits and other lifestyle factors, then examined for hemorrhoids. Results showed that those who reported using a smartphone on the toilet were 46% more likely to have hemorrhoids, even after adjusting for age, exercise, and fiber intake. Notably, smartphone users spent longer periods sitting on the toilet, a behavior believed to increase pressure on anal tissues and contribute to hemorrhoid formation. The findings suggest that advising patients to limit smartphone use in the bathroom could be beneficial.

Summary Table of Key Topics and Findings
| Topic | Key Findings |
|---|---|
| Does smartphone use on the toilet increase the risk of hemorrhoids? | - Multiple studies find a positive association between prolonged smartphone use on the toilet and increased hemorrhoid risk 1 2. - Clinical reports and pilot data suggest that extended phone use while defecating may require medical intervention for hemorrhoidal disease 2. |
| What are the hygiene risks of using smartphones in the bathroom? | - Surveys show that over half of medical staff and students use smartphones in bathrooms, and these devices are often contaminated with bacteria 4 5. - Phones used in toilets have higher microbial loads, raising concerns about transmission of infectious agents 4 5. |
| How prevalent is smartphone use in the bathroom and what are its effects? | - A significant proportion of adults and youth report using smartphones in bathrooms, with many spending more time seated as a result 1 6 7. - Extended screen time and problematic use are linked to sleep disturbances, neck pain, and distraction in daily life 6 7. |
| What behaviors are associated with problematic smartphone use? | - Compulsive smartphone use is common, especially among younger adults, and is associated with increased risk of distraction, sleep problems, and use in situations such as driving or bathroom use 6 7. - Popular apps and digital environments encourage prolonged use, making it easy to lose track of time 1 7. |
Does smartphone use on the toilet increase the risk of hemorrhoids?
Several studies converge on the finding that spending extended time on the toilet with a smartphone is associated with higher rates of hemorrhoids. Both survey-based research and clinical observations suggest that the distraction provided by phones contributes to longer bathroom sessions, which may increase pressure on the anal and rectal veins and lead to hemorrhoidal disease 1 2. Previous studies also report cases where excessive toilet phone use was the only notable risk factor for acute hemorrhoidal problems requiring medical intervention 2.
- Prolonged smartphone use on the toilet is correlated with a higher prevalence of hemorrhoids, independent of other risk factors such as straining or fiber intake 1.
- Clinical case series and anecdotal evidence identify regular, extended toilet phone use as a unique risk factor in patients with acute hemorrhoidal disease 2.
- Both older and newer studies agree that time spent seated during defecation is a modifiable risk factor for hemorrhoids, now exacerbated by the ubiquity of digital devices 1 2.
- The new study's finding of a 46% increased risk in smartphone users aligns with previous observational data and case reports 1 2.
What are the hygiene risks of using smartphones in the bathroom?
The literature documents that smartphones frequently accompany users into bathrooms, contributing to bacterial contamination and potentially facilitating the spread of pathogens. Studies involving healthcare workers and students demonstrate that these devices are rarely disinfected, despite recognition of contamination risks 4 5. Phones used in bathrooms harbor diverse bacterial species, posing additional health threats to users and, in clinical settings, to patients as well 4 5.
- In surveys, 52% of pediatric hospital staff and a majority of university students report using their phones in bathrooms, with a minority cleaning their devices regularly 4 5.
- Microbial analyses show that phones used in toilets have significantly higher bacterial loads, including potentially pathogenic species 5.
- The risk of healthcare-associated infections may be increased by the common use of contaminated phones in clinical environments 4.
- Awareness campaigns and recommendations for regular disinfection are suggested to mitigate these hygiene risks 4 5.
How prevalent is smartphone use in the bathroom and what are its effects?
Smartphone use in bathrooms is widespread among different age groups, with surveys reporting rates from 36% to over 50% in adult and youth populations 1 6 7. This behavior is associated not only with increased time spent on the toilet, but also with broader patterns of extended screen exposure, which have been linked to musculoskeletal discomfort and sleep disturbances 6 7. The new study adds to this evidence by quantifying the impact of bathroom phone use on a specific health outcome (hemorrhoids) 1.
- In the recent study, 66% of adults reported smartphone use on the toilet, and these users spent longer per visit seated than non-users 1.
- Among youth, over half report using phones in the bathroom, with additional negative effects such as neck pain and sleep problems tied to overall screen time 6.
- Compulsive use patterns are more common in younger populations, contributing to risk behaviors across various contexts, including the bathroom 7.
- The prevalence of bathroom phone use suggests that any associated health risks could affect a large segment of the population 1 6 7.
What behaviors are associated with problematic smartphone use?
The broader literature shows that problematic smartphone use is a growing concern, with compulsive behaviors affecting daily routines, sleep, concentration, and safety 6 7. Apps are designed to encourage prolonged engagement, making it easy for users to spend more time than intended in settings such as the bathroom 1 7. These patterns may exacerbate physical health risks, including those identified in the new hemorrhoid study 1.
- Surveys find that 66.7% of French adults exhibit compulsive smartphone use, with high rates of use in the bathroom and before bed 7.
- Excessive use is linked to sleep disturbances, neck pain, lower self-esteem, and distraction in situations requiring focus 6 7.
- Younger adults are more likely to engage in both compulsive and situational (e.g., bathroom) smartphone use 1 6 7.
- The design of smartphone apps and environments is cited as a factor in the loss of time awareness and extended device use 1 7.
