If that extra cup of coffee in the morning sends you running for the bathroom, you might want to rethink your drink, UT Southwestern Medical Center at Dallas physicians said. It’s not true for everyone, but Dr. Gary Lemack, an assistant professor of urology, said products with caffeine, like chocolate, tea and sodas, can cause bladder irritation. “In patients prone to problems with urinary urgency and frequency, we do recommend they avoid what causes the problem,” Lemack says. Caffeine is both a diuretic and a bladder irritant and therefore may result in increased urine production as well as enhanced bladder sensitivity, Lemack says. Other foods that might irritate your bladder include citrus foods, spicy foods and certain cheeses.
