Diastasis Recti (Abdominal Separation)

Diastasis recti is the separation of the rectus abdominis muscles (the “six-pack” muscles) along the midline of the abdomen. This condition commonly occurs during pregnancy but can affect anyone, and understanding it is crucial for proper core recovery and function.

Diastasis recti occurs when the two parallel bands of the rectus abdominis muscles separate along the linea alba (the connective tissue that runs down the center of your abdomen). This separation can range from mild to severe and may occur anywhere along the length of the abdominal muscles.

  • Normal: Rectus muscles close together with minimal gap
  • Diastasis: Gap of 2+ finger widths between muscle bands
  • Functional impact: Affects core stability and support
  • Above the navel (most common)
  • Below the navel
  • At the navel level
  • Full length separation (more severe cases)
  • Growing uterus during pregnancy stretches abdominal muscles and connective tissue
  • Hormonal changes (relaxin) soften connective tissues
  • Increased intra-abdominal pressure from growing baby
  • Multiple pregnancies increase risk and severity
  • Rapid weight gain or significant weight fluctuations
  • Incorrect exercise techniques - especially abdominal exercises
  • Chronic coughing causing repeated pressure increases
  • Heavy lifting with poor technique
  • Genetic predisposition to connective tissue weakness
  • Multiple pregnancies - risk increases with each pregnancy
  • Multiples (twins, triplets) during pregnancy
  • Large babies or excess amniotic fluid
  • Advanced maternal age (over 35)
  • Previous history of diastasis recti
  • Poor core strength before pregnancy
  • Certain body types - taller women may be at higher risk
  • Visible gap or ridge down the center of the abdomen
  • Doming or coning when doing abdominal exercises or sitting up
  • Bulging of abdominal contents when straining
  • Changed abdominal shape - less defined or protruding appearance
  • Lower back pain from reduced core support
  • Pelvic floor dysfunction - incontinence or prolapse
  • Poor posture and spinal alignment issues
  • Reduced core strength and stability
  • Difficulty with functional movements like lifting or carrying
  • Decreased athletic performance
  • Difficulty with everyday activities requiring core stability
  • Compromised breathing patterns
  • Altered movement patterns to compensate for weakness

Position:

  1. Lie on your back with knees bent, feet flat on floor
  2. Place fingertips horizontally across your midline
  3. Lift your head slightly off the ground (mini crunch position)

What to Feel For:

  • Gap width - measure in finger widths
  • Depth - how far fingers sink into gap
  • Tension - quality of tissue between muscles

Measurements:

  • Normal: Less than 2 finger widths
  • Mild: 2-3 finger widths
  • Moderate: 3-4 finger widths
  • Severe: More than 4 finger widths

Check Multiple Locations:

  • Above navel (most common location)
  • At navel level
  • Below navel (2-3 inches down)
  • Gap greater than 2 finger widths
  • Visible doming when activating abdominal muscles
  • Functional difficulties or back pain
  • Persistent symptoms beyond 8-12 weeks postpartum
  • Medical history including pregnancy and delivery details
  • Physical examination of entire core and pelvic region
  • Functional movement assessment
  • Posture and alignment evaluation
  • Pelvic floor assessment (diastasis often occurs with pelvic floor dysfunction)
  • Ultrasound imaging for precise measurement
  • Real-time assessment during various movements
  • Pressure testing to evaluate functional capacity
  • Integration assessment with breathing and pelvic floor

Specialized Exercise Program:

  • Breath-based exercises to activate deep core muscles
  • Progressive loading of abdominal muscles
  • Functional integration with daily activities
  • Postural correction exercises

Core Rehabilitation Phases:

Phase 1: Foundation (0-6 weeks postpartum or initial treatment):

  • Breathing exercises to activate transverse abdominis
  • Gentle pelvic floor activation
  • Postural awareness training
  • Safe movement patterns

Phase 2: Strengthening (6-16 weeks):

  • Progressive core strengthening exercises
  • Functional movements with proper alignment
  • Load management and exercise progression
  • Integration with daily activities

Phase 3: Advanced Function (16+ weeks):

  • Higher-level exercises and sports-specific training
  • Return to previous activity levels
  • Maintenance program development
  • Long-term strategy implementation

Safe Exercises for Diastasis Recti:

  • Dead bug variations
  • Modified planks (wall or incline)
  • Heel slides with core engagement
  • Pelvic tilts and bridges
  • Functional squats and lunges

Exercises to Avoid Initially:

  • Traditional crunches or sit-ups
  • Planks (until appropriate progression)
  • Heavy lifting overhead
  • Intense twisting movements
  • Any exercise causing visible doming
  • Soft tissue mobilization of abdominal fascia
  • Scar tissue treatment (post-cesarean)
  • Postural correction techniques
  • Breathing pattern retraining
  • Immediate postpartum: Gap is largest, tissues are soft
  • 6-8 weeks: Initial tissue healing and hormone stabilization
  • 3-6 months: Significant improvement possible with proper exercise
  • 12+ months: Continued improvement with consistent treatment
  • Severity of separation at start of treatment
  • Consistency with exercise program
  • Overall health and fitness level
  • Breastfeeding status (hormones affect tissue healing)
  • Additional pregnancies during recovery period
  • Complete closure possible in mild to moderate cases
  • Significant improvement achievable in most cases
  • Functional restoration often more important than complete closure
  • Prevention of worsening with proper management
  • Severe functional impairment despite comprehensive conservative treatment
  • Large separation (>5cm) with significant symptoms
  • Associated ventral hernia requiring repair
  • Failed conservative treatment after 12+ months
  • Significant cosmetic concerns affecting quality of life
  • Abdominoplasty (tummy tuck) with muscle repair
  • Endoscopic repair (minimally invasive)
  • Open repair with or without mesh
  • Combined procedures addressing multiple issues
  • Complete conservative treatment trial first
  • Finished childbearing (pregnancy after surgery can cause recurrence)
  • Realistic expectations about outcomes
  • Understanding of risks and recovery time
  • Safe abdominal exercises throughout pregnancy
  • Proper body mechanics for lifting and movement
  • Postural awareness as body changes
  • Breathing techniques to support core function
  • Avoid exercises that cause abdominal doming
  • Early appropriate exercise starting with breath work
  • Gradual progression back to higher-level activities
  • Proper technique with all exercises
  • Professional guidance for safe return to exercise
  • Maintain healthy weight and avoid rapid fluctuations
  • Learn proper lifting techniques
  • Address chronic cough or constipation
  • Build core strength before pregnancy when possible
  • Log rolling to get out of bed rather than sitting straight up
  • Proper lifting technique using legs and core
  • Supportive clothing or abdominal binder when needed
  • Posture awareness throughout daily activities
  • Focus on function rather than just appearance
  • Quality over quantity in exercise selection
  • Listen to your body and avoid activities causing symptoms
  • Progressive overload as strength and control improve
  • Body image support and counseling if needed
  • Realistic expectations about recovery timeline
  • Support groups for women with similar experiences
  • Professional counseling for significant distress
  • 80-90% of women see significant improvement with proper treatment
  • Functional restoration achieved in majority of cases
  • Cosmetic improvement varies but often substantial
  • Prevention of worsening with proper management
  • Early intervention leads to better outcomes
  • Consistency with exercise program
  • Professional guidance for proper progression
  • Patience with gradual improvement process
  • Realistic goals focusing on function first
  • Maintenance exercises to preserve improvements
  • Ongoing awareness of body mechanics
  • Modifications for future pregnancies
  • Regular assessment if symptoms recur

Consult a healthcare professional if you experience:

  • Gap greater than 2 finger widths that persists beyond 8 weeks postpartum
  • Visible doming when doing abdominal exercises
  • Back pain or pelvic floor symptoms
  • Functional difficulties with daily activities
  • Concerns about appearance or core strength
  • Pelvic floor physiotherapists with postpartum specialization
  • Women’s health physiotherapists trained in core rehabilitation
  • Exercise physiologists with prenatal/postnatal certification
  • Plastic surgeons specializing in post-pregnancy reconstruction (if surgery considered)

Remember: Diastasis recti is a common and treatable condition. With proper assessment, appropriate exercise progression, and patience, most people can achieve significant functional improvement and restore core strength and stability.


For comprehensive assessment and treatment of diastasis recti, consult with a pelvic floor physiotherapist or women’s health specialist experienced in core rehabilitation and postpartum recovery.
