Women who developed diabetes while pregnant were nearly twice as likely to develop an overactive bladder before menopause than women who did not have diabetes. While nearly 1 in 8 adults has an overactive bladder, the underlying cause of the condition is unknown in the vast majority of cases, according to UTMB’s Dr. Tristi Muir, associate professor of obstetrics and gynecology and dailyRx contributing expert. “Although gestational diabetes mellitus may contribute to development of overactive bladder later in life, it is only one piece of the complex overactive bladder puzzle that sends many women running to the nearest toilet,” Muir said. “Further research into a comprehensive understanding of overactive bladder is ‘urgently’ needed,” she said.
