Yes you do! There is no doubt that pregnancy and childbirth can play a part in weakening pelvic floor muscles even if your baby is delivered by caesarean section. Research has also shown that even ladies who have not had children can still be susceptible to pelvic floor weakness. This is usually due to the combination of the reduction in oestrogen during and after the menopause and the ageing process. Being overweight or constipated also does not help and the muscles can be affected by external influences such as smoking.
