Following delivery of your baby it can happen that when you laugh, cough, sneeze or even when your bladder is very full you may pass some urine accidentally. Pelvic floor exercises are important and you need to pay particular attention to performing these in the postnatal period.
You may need a referral to a physiotherapist if the situation does not improve. Controlling weight and constipation can also help. It is important to drink fluids regularly and empty your bladder frequently.
