The Biggest Mistake People Make On The Toilet | Dr. Trisha Pasricha

TL;DR

Using your smartphone on the toilet causes a 46% increased hemorrhoid risk by extending sitting time and disrupting pelvic floor muscle coordination.

Key Points

• 1.Dr. Trisha Pasricha is a neurogastroenterologist at Beth Israel studying the gut-brain connection, including how Parkinson's disease may originate in the gut.
• 2.A third of people avoid seeing their doctor about bowel symptoms due to embarrassment, and 40% of Americans say bowel habits disrupt their daily lives.
• 3.The 5-minute toilet rule traces back to a 1989 Lancet study of ~100 patients that found newspaper reading correlated with hemorrhoids — the best data available for decades.
• 4.Dr. Pasricha's own study at Beth Israel found bringing a smartphone to the bathroom was associated with a 46% increased risk of hemorrhoids found during colonoscopy.
• 5.Smartphone users were 5 times more likely to spend more than 5 minutes on the toilet, usually unintentionally due to doom-scrolling.
• 6.Hemorrhoids are engorged veins caused by prolonged pressure on an open bowl with no pelvic floor support; the same risk factors (low fiber, straining) also cause varicose veins.
• 7.95% of Americans don't reach their daily fiber goals; psyllium husk is the oldest and best-studied fiber supplement, shown to help with both constipation and diarrhea.
• 8.Microbiome changes from increased fiber intake take 2–3 months; bloating from fiber is common initially and patients should increase intake slowly to allow gut adaptation.
• 9.IBS patients have measurable abnormalities — nerve cells in the enteric nervous system fire at a lower pressure threshold than non-IBS patients — disproving the 'all in your head' myth.
• 10.One-third of people with constipation who fail laxatives actually have a pelvic floor coordination problem, diagnosed via anorectal manometry using a sensor-equipped balloon.
• 11.A 2021 Nature study from Belgian neurogastroenterologists found some IBS patients had local mast-cell allergic reactions to food antigens sprayed on their mucosa during endoscopy — invisible on blood tests.
• 12.The low-FODMAP diet should only last ~2 weeks as an elimination phase, followed by systematic reintroduction of food groups one at a time, ideally supervised by a registered dietitian.
• 13.TikTok's top IBS recommendations are abdominal massages and probiotics, while fiber — the most evidence-backed intervention — rarely appears on those lists.
