Overactive bladder is characterized by a sudden spasming where the bladder will suddenly squeeze without your knowledge or desire. “It’s that uncomfortable, ‘gotta-go’ feeling,” says Dr. Michael Kennelly, a specialist in overactive bladders. This leads to frequent trips to the bathroom, which can be distressing. Also bothersome is when the bladder leaks without your knowledge or desire. “That’s a call to action,” says Kennelly. “It makes women say that they need to see a physician.”
