Why smartphone use on the toilet may increase hemorrhoid risk

Adults using smartphones on the toilet spent significantly more time seated and had 46% higher odds of hemorrhoids on colonoscopy. The cross-sectional study suggests prolonged sitting, not straining, may be the key driver of hemorrhoid risk.

AI use in colonoscopy may weaken doctors' detection skills over time

The introduction of artificial intelligence (AI) to assist colonoscopies is linked to a reduction in the ability of endoscopists (health professionals who perform colonoscopies) to detect precancerous growths (adenomas) in the colon without AI assistance, according to a paper published in The Lancet Gastroenterology & Hepatology journal.
