Coffee‘s Call of Nature: Why Your Morning Brew Sends You Running, According to a Florida Doctor
ORLANDO, FL – Ever wonder why your morning coffee is so reliably followed by a trip to the bathroom? It’s not just you. A Florida-based gastroenterologist explains the physiological reasons behind coffee’s laxative effect, revealing a complex interplay of hormones and muscle contractions triggered by the popular beverage.
For millions who rely on coffee to kickstart their day, the resulting gastrointestinal response is a common – and sometimes inconvenient – reality. Understanding why coffee stimulates bowel movements can help individuals manage their routines and address any related digestive concerns.The effect isn’t simply due to coffee’s caffeine content, but a combination of factors impacting the digestive system.
Dr. John P. Cunha, a gastroenterologist at South Florida Gastroenterology Associates, explains that coffee stimulates contractions in the colon, known as colonic motility. “Coffee doesn’t just contain caffeine; it contains over 100 different compounds that can affect the gut,” he stated. These compounds, combined with caffeine, increase the urge to defecate.
Specifically, coffee appears to increase levels of gastrin and cholecystokinin, hormones that stimulate colonic activity. Gastrin, for example, prompts the colon to contract, moving waste along. Caffeine also boosts acid production in the stomach,which can further accelerate the digestive process.
Though, the effect varies significantly from person to person. Individuals with Irritable Bowel Syndrome (IBS) may experience a more pronounced response,while others might potentially be less sensitive. Cunha notes that the temperature of the coffee can also play a role, with hot liquids generally having a stronger effect on the bowels.
While generally harmless, frequent or urgent bowel movements triggered by coffee could indicate an underlying digestive issue. Individuals experiencing persistent discomfort or changes in bowel habits should consult a healthcare professional.
