Abdominal Diastasis
Diastasis recti occurs when the rectus abdominis muscle separates lengthwise along the linea alba — the connective tissue that connects both sides of the abdomen. This separation can weaken the core, cause lower back pain, postural changes, and even impact the function of internal organs.
It is especially common after pregnancy due to the stretching of the abdomen to accommodate the growing baby, but it can also occur due to excessive abdominal strain, obesity, or abdominal surgery.
Clinical evaluation
The assessment can be done palpatively, ideally complemented with ultrasound for greater accuracy.
- The client lies on her back, with her knees bent and feet flat on the floor;
- A slight flexion of the head and shoulders is requested, activating the rectus abdominis;
- The professional positions the fingers in the midline (above, at the height of and below the navel) to check the width of the separation;
- Diastasis is considered when the separation is greater than 2 cm or when there is no tension in the linea alba, even with correct muscle activation.
What can be done to improve or reverse it?
In most cases, diastasis can be reversed with specific exercises and changes in movement habits:
- Deep core training, focusing on the transverse abdominal muscle;
- Functional breathing exercises, such as diaphragmatic breathing;
- Clinical Pilates adapted to individual needs.
The following should be avoided:
- Traditional sit-ups and planks;
- Movements that cause increased intra-abdominal pressure;
- Lifting weight incorrectly.
Conclusion
Diastasis recti is a common but often overlooked condition. Correct identification and treatment are essential for the functional and aesthetic health of the abdomen. Having the support of a physical therapist specializing in pelvic health or a personal trainer experienced in postpartum recovery can speed recovery and prevent relapses.
