Using your phone on toilet may give you hemorrhoids: study

2025-09-0512:179473www.nbcnews.com

Endlessly scrolling through social media while on the toilet could result in hemorrhoids, a new study found. Plus, experts say, it's gross.

Of all the crappy ways smartphones have affected our health, this one is a real kick in the pants.

A first-of-its-kind study links excessive scrolling on the phone while sitting on the toilet with hemorrhoids.

(Insert poo emojis.)

But, seriously. Sitting on an open bowl offers no support for the pelvic floor. That puts pressure on veins in the rectum, making them swollen and inflamed.

“The longer you sit on the toilet, the worse it is for you,” said Dr. Trisha Pasricha, director of the Beth Israel Deaconess Medical Center’s Institute for Gut-Brain Research Institute in Boston. Pasricha is also an author of the study, which was published Wednesday in PLOS One.

And smartphones are designed to keep people fixated for as long as possible. “They’re completely consuming to us in ways that wasn’t happening to the casual bathroom reader in the 80s,” Pasricha said. “They could much more easily put the newspaper down and get up and leave.”

Pasricha and colleagues surveyed 125 adults just before they were about to have a routine colonoscopy to screen for colorectal cancer.

Eighty-three (66%) of the participants admitted to using their phones in the bathroom — mostly to catch up on news of the day and scroll through social media.

Gastroenterologists performing the colonoscopies looked for evidence of inflamed veins, or hemorrhoids. People who said they took their phone into the bathroom were 46% more likely to have hemorrhoids compared to the others.

The risk remained even when researchers accounted for other factors associated with hemorrhoids, including dietary fiber, exercise and constipation or straining while using the toilet.

Hemorrhoids aren’t necessarily dangerous, but they can be bothersome, itchy and even painful. They also bleed sometimes, understandably causing concern and leading to nearly 4 million doctor’s office and emergency department visits a year.

Over time, “pelvic floor dysfunction can also lead to incontinence, worsen constipation and be associated with rectal pain,” said Dr. Reezwana Chowdhury, an inflammatory bowel disorder specialist at the Johns Hopkins University School of Medicine. Chowdhury was not involved with the new research.

What’s more, microscopic particles from urine and feces are sent flying through the air when a toilet is flushed. Taking a phone into the bathroom, Chowdhury said, “is kind of gross.”

Younger patients

In the new study, smartphone users in the bathroom tended to be younger, meaning adults in their 40s and 50s, versus people over age 60.

Dr. Robert Cima, a colorectal surgeon at the Mayo Clinic in Rochester, Minnesota, said he’s noticed an uptick in recent years of people coming in with hemorrhoids.

“I am seeing younger, earlier- and middle-aged people having more hemorrhoidal complaints, but I can’t tie it to smartphones,” said Cima, who was not involved with the new study. “Maybe it’s because they’re using smartphones or they have better access to care or they’re not eating appropriately.”

The 5-minute rule

The experts agreed that business on the toilet should take no longer than 5 minutes.

More than 37% of study participants who used a smartphone in the bathroom stayed for longer than that, compared to 7% of people who kept their phones out of the bathroom.

Pasricha and other experts do not advocate for taking a phone into the bathroom. If you absolutely must, set a timer.

“If the magic is not happening within five minutes, it’s not going to happen,” Pasricha said. “Take a breather and try again later.”

    Leonardo da Vinci in his Codex Atlanticus said “Do not delay or prolong your visits to the lavatory”. Looks like that was some good advice.

      There is a silly scene in a movie called ‘Liar Liar’ that I used to love as a kid about the importance of not delaying a visit; the underlying plot is that Fletcher (Jim Carrey) is unable to is lie following his son making a birthday wish.

      Fletcher: Your honor, would the court be willing to grant me a short bathroom break?

      Judge: Can't it wait?

      Fletcher: Yes it can. But I've heard that if you hold it you could damage the prostate gland, making it very difficult to get an erection, or even become aroused!

      Judge: Is that true?

      Fletcher: It has to be!

      Judge: In that case I'd better take a quick break myself.

    Haemorrhoids are caused by too much straining, which is caused by bad posture during defecation. The closer you're to a squatting position, the less straining you need. Use a footrest to raise your leg (or as I call it: a stool stool, hehehe).

      The toilet stool (Squatty Potty is probably the most well known brand name) is game changing. Highly recommend. That may be some of the lowest cost to benefit thing I've found for the home.

      The only downside is that you'll miss it whenever nature calls outside the home.

      Also a bad diet or possibly poor hydration. Defecating should not require strain.

        Also, agitating the area with dry wiping vs. the soothing waterbeam of a bidet.

          I have not had to strain since using a bidet. It’s like magic.

        Insufficient hot sauce is usually the culprit.

        I've had constipation maybe twice in my life.

      Two double shots of espresso and straining is a thing of the past, regardless of diet.

      Learning to relax your pelvic floor is helpful too. You should be opening the door, not pushing things through it :)

    There is no causal link here. It's merely associative - it could be that people with hemorrhoids spend more time on the toilet.

      According to Wikipedia affluent people get more hemorrhoids, maybe they are sitting managing their money

      Definitely feels like a great Sim City 3000 news ticker item.

      >> There is no causal link here.

      One already exists. Sitting vs hovering is already known to cause hemorrhoids. Using your phone probably increases sitting time.

        Sitting in general causes hemorrhoids?
