During pregnancy, the abdominalwall in the centre of the abdomen between the two halves of the midline abdominal muscle is weakened.
The abdominal wall is made up of supporting and binding tissue, including collagen fibres. Due to the pregnancy hormones, the tension of the fibres decreases and they begin to stretch. After delivery, this process will redress itself and the collagen fibres will regain their normal tractive force. However, long term stretching or ever tearing of the fibres can lead to the binding tissue not being able to recover fully. The two halves of the abdominal wall will thus remain separated, which, in medical terms, is referred to as diastasis.
You can easily check your diastatis yourself or ask one of our trainers to help you with that.
