A new study from the United States suggests that using a smartphone while sitting on the toilet may increase the risk of haemorrhoids, a painful condition that affects millions of people worldwide.
Researchers led by Chethan Ramprasad, found that modern bathroom habits—particularly prolonged phone use—may worsen vein-related problems in the anal region.
The study, published in PLOS One, highlights how everyday technology habits can have unexpected health consequences and offers guidance for healthcare professionals on advising patients about safer bathroom routines.
The research involved 125 adults who were undergoing routine colonoscopy screenings. Participants completed surveys detailing their daily activities and bathroom habits, while doctors examined them for signs of haemorrhoids.
The findings revealed that 66% of participants used their phones in the bathroom, with younger individuals more likely to engage in the habit. Smartphone users were found to have a 46% higher risk of developing haemorrhoids compared with those who did not use their phones while on the toilet.
Senior author Trisha Pasricha explained that smartphones tend to prolong bathroom visits because people remain engaged with their devices. About 37% of smartphone users spent more than five minutes in the restroom, compared with only 7% of non-users.
Many participants reported using their phones to access social media or browse news. Prolonged sitting on the toilet can increase pressure on anal veins, potentially leading to swelling, discomfort, and even rectal bleeding.
Researchers advised people to avoid taking smartphones into the bathroom and limit time spent on the toilet, as these simple habits may help reduce the risk of haemorrhoids.
