Brittany Mahomes urges moms to "take care of your pelvic floor." Here's why experts agree.

Brittany Mahomes, the wife of quarterback Patrick Mahomes, is urging women to take care of their pelvic floor.

"Just a daily reminder: Once you have kids please take care of your pelvic floor. Seriously," the 28-year-old mother of two wrote in an Instagram Story last week, signing the message: "From: A girl with a fractured back."

Though specific details about Mahomes' case are not publicly known, a fracture from a weak pelvic floor is typically rare, Dr. Fatima Naqvi, the medical director at Atlantic Medical Group Outpatient Obstetrics and Gynecology, told CBS News.
