Neurologist Warns: Faint Risk from Long Toilet Stays

Spending excessive time on the toilet poses a significant health risk, according to neurologist Dr. Baibing Chen. He explains that prolonged sitting can cause blood to pool in the legs. Suddenly standing up can then lead to insufficient blood flow to the brain, potentially causing fainting or even a subdural hematoma, a serious brain bleed.

Dr. Chen shared an instance where a 50-year-old man experienced a head bleed after fainting from sitting on the toilet for 30 minutes. The expert noted that the risk depends on individual factors like hydration and autonomic system health. Straining during bowel movements, known as the Valsalva maneuver, can worsen the situation by expanding blood vessels and reducing heart rate.

This maneuver also increases chest pressure, hindering blood return to the heart. Mayo Clinic experts confirm that extended toilet sitting is a common cause of hemorrhoids, where anal veins swell due to pressure. They advise keeping bathroom visits brief and addressing potential causes like insufficient fiber or water intake if difficulty occurs.
