I've read ab separation (diastasis recti) is common In multiple pregnancies so just wanted to see if anyone else has had it? And if anyone's had physio or surgery for a gap over 5cm which has helped? I had a abdominal 5 cm gap with my 1st now 2, I closed this abit with exercise and the gap was around 3cm when I got pregnant with twins which I got a very big bump with so it's not a surprise I've got a bigger ab gap than 1st time round over 5cm. I'm getting bad back pain when lifting my twins and toddler alot so my GP said to try specialist physio. Just wondered if this worked for anyone with over a 5cm gap? Or if it didn't how long did they have to do physio before they had surgery for this?
