Rectus abdominis laxity—sometimes called abdominal muscle laxity or, in some cases, diastasis recti—is a condition in which the rectus abdominis muscles (the “six-pack” muscles) become stretched, weakened, or separated. This guide is meant to explain in very simple terms what this condition is, why it happens, how it is diagnosed, and what treatment options exist.

Rectus abdominis laxity occurs when the muscles that run vertically along the front of your abdomen lose their firmness or become separated. This separation can lead to a visible gap along the midline of the belly, sometimes making the stomach appear bulged or “loose.” Although it is often seen in postpartum women, other factors like aging, obesity, or improper exercise techniques can also contribute.

Key Points:

• Also known as: Abdominal muscle laxity, diastasis recti (especially after pregnancy)
• Who is affected: Common in postpartum women, older adults, and individuals who have experienced heavy strain or injury to the abdominal area
• Main concern: Reduced core stability, potential for back pain, and in some cases, an increased risk of hernias

Pathophysiology of Rectus Abdominis Laxity

Understanding how the rectus abdominis works helps explain why laxity occurs. Below is a breakdown of the muscle’s structure, its blood and nerve supply, and its functions.

Structure of the Rectus Abdominis

• Location: The rectus abdominis is a long, paired muscle that runs vertically on each side of the midline of the abdomen.
• Appearance: Often visible as the “six-pack” when well-toned.
• Attachment: It stretches from the pubic bone at the lower part of the pelvis to the rib cage at the top.

Blood Supply

• Major Arteries:
  • Superior Epigastric Artery: Supplies blood from the upper part of the muscle.
  • Inferior Epigastric Artery: Delivers blood to the lower portions.
• Importance: A rich blood supply is essential for muscle repair and maintenance. When these vessels are compromised or when the muscle is overstretched, healing can be slower.

Nerve Supply

• Primary Nerves: The intercostal nerves (branches that run between the ribs) supply the rectus abdominis.
• Role of Nerves: They help control muscle movement and relay signals that allow the muscle to contract. When the nerve supply is affected, muscle function can decline, contributing to laxity.

Functions of the Rectus Abdominis

• Trunk Flexion: Helps bend the torso forward (think of doing a crunch).
• Core Stability: Supports your spine and helps maintain posture.
• Respiratory Assistance: Plays a role in forced expiration (like during vigorous exercise).
• Protection: Acts as a cushion for internal organs.

Types of Rectus Abdominis Laxity

Rectus abdominis laxity can vary in severity and may be classified based on its cause or how pronounced the separation is. Common types include:

• Mild Laxity: Small separation, often noticed as a slight bulge.
• Moderate Laxity: More noticeable separation with some impact on core strength.
• Severe Laxity (Diastasis Recti): Significant separation that can affect posture, movement, and may require intervention.
• Postpartum Laxity: Commonly occurs after pregnancy when the abdominal wall stretches to accommodate a growing baby.
• Age-related Laxity: Occurs gradually with aging due to natural loss of muscle tone.
• Traumatic Laxity: Results from physical trauma or surgery, affecting muscle integrity.

Causes of Rectus Abdominis Laxity

Multiple factors can lead to the weakening or separation of the rectus abdominis muscles. Here are 20 possible causes:

1. Pregnancy: The growing fetus stretches the abdominal wall.
2. Rapid Weight Gain: Excess weight can put pressure on the abdominal muscles.
3. Aging: Natural loss of muscle tone over time.
4. Poor Posture: Continuous slouching or improper sitting/standing can strain the muscles.
5. Excessive Abdominal Strain: Overworking the abdominal muscles without proper support.
6. Heavy Lifting: Lifting weights or heavy objects incorrectly can lead to muscle strain.
7. Genetic Predisposition: Some people may naturally have looser connective tissues.
8. Connective Tissue Disorders: Conditions that affect the strength of connective tissues.
9. Surgical Scars: Abdominal surgeries can weaken the muscle structure.
10. Abdominal Trauma: Injury to the abdomen may result in muscle damage.
11. Chronic Coughing: Repeated coughing can place stress on the abdominal wall.
12. Obesity: Excess fat can stretch and weaken the muscles.
13. Sedentary Lifestyle: Lack of regular exercise can reduce muscle tone.
14. Hormonal Changes: Hormones during pregnancy or menopause can affect muscle elasticity.
15. Improper Exercise Techniques: Wrong form during workouts can injure the muscles.
16. Overtraining: Excessive exercise without adequate rest.
17. Nutritional Deficiencies: Inadequate protein or vitamins can impair muscle repair.
18. Inflammatory Conditions: Inflammation can weaken muscle tissue.
19. Neuromuscular Disorders: Conditions that affect nerve and muscle function.
20. Chronic Stress: Elevated stress hormones can contribute to muscle weakness.
