Do you ever pee a little when you sneeze? If you do, you’re not alone. Pelvic floor dysfunction is incredibly common, affecting a quarter to a third of women the US. Pregnancy and childbirth are common culprits, but so are injuries, trauma, or even too much Pilates. Most people think we should all be tightening our pelvic floors and doing Kegel exercises all day, but an overly tight pelvic floor isn’t much better than an overly loose one. Dysfunction in this area in either direction can cause pelvic pain, low back pain, constipation, painful sex, or—you guessed it—peeing when you sneeze.
