Diastasis recti is a separation of the two “six‑pack” abdominal muscles along the midline of your belly, caused by stretching and thinning of the connective tissue (linea alba).

What is diastasis recti?

Diastasis recti (also called rectus diastasis) happens when the left and right rectus abdominis muscles move farther apart than normal.

The tissue that normally holds them together, the linea alba, becomes thinned and widened, allowing a gap and often a visible midline bulge from the breastbone down toward or past the belly button.

Who gets it and why?

  • Very common during and after pregnancy, affecting around 6 in 10 women postpartum.
  • Can also occur in men, newborns, and people with increased abdominal pressure (heavy lifting, chronic coughing, significant weight change).
  • As the uterus or abdomen expands, the linea alba stretches like a rubber band; if it loses elasticity, the gap does not fully close.

Typical signs and symptoms

  • A long, vertical bulge or “doming” in the middle of the abdomen, especially when you sit up, cough, or do a crunch.
  • A visible or palpable gap between the two sides of the abs when lying on your back and slightly lifting your head.
  • Feeling of core weakness, trunk “instability,” or poor posture.
  • It can contribute to low back pain and urinary stress incontinence in some people.
  • Many people have no pain; they mainly notice the shape change or “still look pregnant” months after birth.

Is it dangerous?

  • Diastasis recti itself is usually not considered dangerous or a true hernia, because the fascia is stretched but not torn open.
  • However, it can affect quality of life by causing weakness, discomfort, or dissatisfaction with abdominal appearance.
  • A true hernia (a defect in the abdominal wall where tissue protrudes through) is different and may need more urgent medical attention.

Treatment and management

Most cases can improve with time and targeted exercise:

  • Postpartum core‑strengthening and physical therapy focusing on deep abdominal muscles and pelvic floor (not just standard crunches).
  • Avoid or modify activities that sharply increase abdominal pressure (intense sit‑ups, heavy lifting with poor form) early in recovery.
  • Guided rehab from a physiotherapist trained in diastasis recti is often recommended, especially for moderate or severe gaps.
  • In resistant, severe cases with functional problems or major bulging, surgical repair (often combined with abdominoplasty) can be considered.

When to see a doctor

  • If you notice a persistent midline bulge or gap that worries you after pregnancy or weight change.
  • If you have pain, vomiting, or a hard, tender lump (to rule out hernia or other conditions).
  • If back pain, pelvic floor issues, or core weakness are limiting your daily life.

Aspect Details
Definition Widened gap between left and right rectus abdominis muscles due to stretching/thinning of the linea alba.
Common in Pregnant and postpartum women; can also affect men, newborns, and anyone with chronically increased abdominal pressure.
Main signs Midline abdominal bulge, visible or palpable gap, worsens with sit‑up or strain.
Possible issues Core weakness, back pain, urinary stress incontinence, cosmetic concerns.
Treatment Targeted physiotherapy and exercises; surgery reserved for severe, persistent cases.
Urgent signs Painful, hard lump, redness, or systemic symptoms, which may suggest a hernia or other problem rather than simple diastasis recti.
