Pregnancy brings about remarkable changes in the body, including abdominal separation, a condition known as Diastasis Recti (DR). The pain associated with this separation is a common concern that prompts a search for understanding and relief. While stretching the abdomen is natural to accommodate a growing baby, the resulting discomfort and functional changes can interfere with daily life. Understanding the mechanics of this separation and management strategies provides reassurance and a clear path toward physical comfort.
Defining Abdominal Separation During Pregnancy
Diastasis Recti is the widening of the gap between the two large muscles that meet in the center of the abdomen. These muscles are the rectus abdominis, often called the “six-pack” muscles, which run from the ribs down to the pubic bone. They are held together by a strip of connective tissue called the linea alba.
As the uterus expands during pregnancy, pressure is placed on the abdominal wall. This pressure causes the linea alba to stretch and thin, allowing the rectus abdominis muscles to pull apart sideways. The condition is defined by this widening, or diastasis, of the connective tissue. This separation occurs because the body is making room for the baby, and it is a very common occurrence, affecting more than half of women who have delivered a baby.
The separation typically develops in the third trimester when the baby’s growth is most rapid. While the tissue is elastic and often retracts after delivery, it can lose its ability to snap back, leaving a gap. A separation is generally diagnosed as Diastasis Recti when the gap is wider than two centimeters, or about two finger-widths.
Why Does Separation Cause Pain
The separation itself is not inherently painful, but the resulting loss of stability in the body’s core structure leads to significant discomfort. The rectus abdominis muscles are a major component of the core, helping to stabilize the spine and pelvis. When the central support system is compromised, the body must compensate by placing undue strain on surrounding structures.
This instability often results in lower back pain because the weakened front wall forces the lower back muscles to overwork to maintain posture. The lack of abdominal integrity also affects the pelvic floor, which works in tandem with the deep core muscles to manage pressure. This imbalance can lead to pelvic or hip pain and symptoms like urinary leakage or constipation.
Daily activities involving increased intra-abdominal pressure can also cause sensations of pulling, stretching, or sharp pain in the midsection. Actions such as coughing, sneezing, laughing, or even changing position in bed can push the internal organs through the weakened midline, resulting in a visible bulge or “doming.” This functional weakness makes routine movements difficult and contributes to discomfort experienced during pregnancy.
Recognizing Risk Factors and Misconceptions
Several factors can increase the likelihood of abdominal separation.
Risk Factors
Carrying multiple babies, having multiple pregnancies, or having pregnancies spaced less than 12 months apart are risk factors. Advanced maternal age, being over 35, and having a baby with a high birth weight can also contribute to the condition. However, Diastasis Recti is not selective and can affect any pregnant person regardless of fitness level.
Misconceptions
A common misconception is that all abdominal exercises should be avoided during pregnancy. While movements that cause the abdomen to bulge or cone, like traditional crunches or sit-ups, can exacerbate the separation, safe core work is beneficial. Focused exercises that strengthen the deeper core muscles, such as the transverse abdominis, can help stabilize the trunk.
Another misunderstanding is that surgery is the only way to fix the separation. In most cases, the condition can be significantly improved through targeted, non-surgical interventions. Although a visible abdominal bulge can be a cosmetic concern, the condition is primarily a functional issue that impacts core stability and physical comfort.
Safe Strategies for Management and Recovery
Managing Diastasis Recti during pregnancy and in the postpartum period requires careful attention to body mechanics and movement. The “log roll” maneuver is recommended for getting out of bed or standing up from a reclined position. This involves rolling onto one side first and then using the arms to push the body up, which avoids putting direct strain on the rectus abdominis.
Avoid high-pressure movements that cause the abdomen to dome, such as lifting heavy objects, straining during bowel movements, or performing exercises like crunches and full planks. Focus should shift to exercises that activate the deep core muscles, the transverse abdominis. These exercises involve gentle contractions, often paired with breathwork, to draw the belly button toward the spine and provide internal support.
Consulting a pelvic floor physical therapist is effective for management and recovery. A physical therapist can provide a personalized program that progresses safely and teaches proper posture and lifting techniques to minimize strain. Postpartum, abdominal bracing or compression garments may be recommended for short-term external support, particularly in the first few weeks after delivery. Surgery is reserved for severe cases or when a hernia is present, and only after conservative treatment methods have not been successful.
