Abdominal muscle separation (or Diastasis Recti) is a completely normal and necessary part of pregnancy. As your baby grows your abdominal area accommodates by stretching the skin, muscles and connective tissue. During this process the line down the middle of your abdominals (known as your Linea Alba) stretches also and this increases the distance between the two sides of your rectus muscles.
There are many factors that we think might affect how large your gap may be during/after pregnancy, including:
- How many babies you were carrying (eg, twins, triplets!)
- Maternal BMI
- Narrow pelvis
- How many pregnancies you have had in your lifetime
- How strong/weak your core was pre-pregnancy (as your muscles support the linea alba) and how active/inactive you were during your pregnancy (as this has an affect on your general strength and abdominal control)
- Genetics; connective tissue varies between individuals and we believe some of this is based around genetics.
Again, these are very much factors that remain to be further researched but we think they might have some influence on Diastasis Recti.
What does this mean as a mum?
After you have had a baby you may notice that your abdominals do not feel or look the same as they did before pregnancy. Approximately more than half of women will have a gap in their abdominals at 8 weeks post birth which means that this is a very common issue postpartum and something that I see a lot of in the clinic.
The biggest issue? Abdominal separation is linked to lower back and pelvic pain as the abdominal wall is part of the structures responsible for keeping your pelvis strong as well as protecting and supporting your spine! Whilst aesthetically your abdominals may look different or you notice a gap, or a doming in the centre, there is also the possibility for the physical strength in your abdominal wall to have been reduced (with or without a gap being present!).
Gaps can vary from 2-3cm wide and 12-15cm in length to 12-20cm widths and the full length of the abdominals. Some of these gaps reduce quickly, some don't. Some of these gaps are supported by great functioning TA (transverse abdominis muscle) and core muscles, some are not.
What can a Physiotherapist help with?
A physiotherapist can assess your core function, assess basic pelvic floor control and function (no vaginal exam), assess pelvic control and strength and postpartum posture! All of these components have an affect on pain, control, return to exercise and fitness activities so it is very important to get assessed so that you can get strong for all the varied activities of motherhood and for your active lifestyle!
A physiotherapist can help to re-educate your abdominal wall function, help you strengthen and improve your control and support your daily activities. Generally this is done through learning proper breathing mechanics, posture, activation and of course - exercises!!
Will I need surgery?
This is a really common question and not one that we can answer easily. Surgery is potentially indicated in large diastases or when severe dysfunction is present. However! It is really important to start learning how to build strength and tension in the anterior abdominal wall so physiotherapy management pre-surgery and post surgery is also often indicated.
It's best to come and see the experts for assessment rather than fretting on your own as to what might be going on (or consulting Dr Google). Come and see our expert team in the clinic to put your mind at ease and have you on the road to recovery today!
