If you have recently been pregnant or are noticing changes in your abdominal strength and shape, you may be wondering whether you have a separation in your core. A feeling of weakness, visible doming, or reduced support during movement can all point toward diastasis recti. Understanding how to check for this safely is an important first step. At Diastasis Recti Rehabilitation, we guide you through accurate assessment and structured recovery so you can rebuild strength with confidence and clarity.
Why Checking for Abdominal Separation Matters
Diastasis recti is not only about how your abdomen looks. It directly affects how your core functions. Your abdominal muscles, connective tissue, diaphragm, and pelvic floor work together to stabilise your body. When there is a separation, this system may not perform efficiently.
Checking for abdominal separation helps you understand whether your core is providing the support you need. It also helps guide the right rehabilitation approach. Without proper assessment, it is easy to follow generic advice that may not match your body’s needs.
What You Are Looking For
When checking for diastasis recti, the focus is not only on the width of the gap. It is equally important to assess the depth and the tension of the tissue between the muscles.
Width of the Gap
This refers to the distance between the two sides of the rectus abdominis muscles. It is often measured in finger widths, although this is a rough guide rather than a precise measurement.
Depth of the Tissue
Depth indicates how much the connective tissue sinks when pressure is applied. A deeper gap may suggest reduced support through the abdominal wall.
Tension and Control
Tension refers to how well the tissue resists pressure and supports movement. Even if a gap is present, good tension can mean your core is functioning well. Poor tension, on the other hand, often leads to instability and weakness.
How to Perform a Self-Check
A basic self-check can give you an initial understanding of your abdominal separation. This should be done gently and without forcing movement. The goal is awareness, not diagnosis.
Step 1: Position Yourself Correctly
Lie on your back with your knees bent and feet flat on the floor. Keep your body relaxed and your head supported.
Step 2: Locate the Midline
Place your fingers just above your belly button along the midline of your abdomen. This is where the linea alba runs between the abdominal muscles.
Step 3: Perform a Small Lift
Gently lift your head and shoulders slightly off the floor, as if beginning a small crunch. This activates the abdominal muscles enough to feel the edges of the separation.
Step 4: Assess the Gap
Use your fingers to feel how many finger widths fit between the muscle edges. Move your fingers slightly above and below the belly button, as separation can vary along the midline.
Step 5: Check the Depth
Press gently into the gap. Notice whether your fingers sink deeply or whether there is resistance. This gives you an idea of tissue tension.
What a Normal Finding Looks Like
In the early weeks after pregnancy, some degree of separation is expected. A small gap with good tension is often considered within normal recovery. Over time, with appropriate rehabilitation, this gap should reduce and the tissue should regain strength.
It is important not to focus only on closing the gap. Functional improvement, including strength, control, and stability, is the priority.
Signs That You Should Seek Professional Assessment
While a self-check is helpful, it does not replace a full clinical assessment. There are specific signs that indicate you would benefit from guided support.
Persistent or Wide Separation
If the gap feels wide or has not improved several weeks after birth, it is worth having it assessed. This allows for a targeted rehabilitation plan.
Poor Tissue Tension
If your fingers sink deeply into the gap with little resistance, this suggests reduced support in the abdominal wall.
Visible Doming During Movement
If you notice a bulge along the midline when you sit up, lift, or exercise, this indicates that pressure is not being managed effectively.
Associated Symptoms
Lower back pain, pelvic floor issues, or a feeling of instability are important indicators that your core system needs support.
Why Self-Checks Have Limitations
While self-assessment is useful for awareness, it has limitations. Finger-width measurements are not precise and do not fully capture how your core functions during movement.
A comprehensive assessment looks at how your body manages load, how your breathing pattern supports your core, and how your muscles coordinate during everyday tasks. This level of detail cannot be captured through a simple self-check.
What a Professional Assessment Includes
At Adam Vital, assessment is structured and focused on function. We do not only measure separation. We evaluate how your entire core system works together.
Movement Assessment
We observe how you move through tasks such as sitting, standing, lifting, and bending. This helps identify compensations and areas of weakness.
Core Activation and Control
We assess how well you can engage your deep core muscles and whether they support your movement effectively.
Breathing Mechanics
Your breathing pattern plays a key role in core stability. We assess whether your diaphragm is working in coordination with your abdominal wall and pelvic floor.
Pelvic Floor Integration
The pelvic floor is closely linked to abdominal function. We assess how these systems work together to provide support and control.
Common Mistakes When Checking for Diastasis Recti
Many people unintentionally make errors when performing a self-check. These can lead to inaccurate conclusions or unnecessary concern.
Checking Too Early or Too Frequently
In the early postpartum period, your body is still healing. Frequent checking can create anxiety without providing meaningful insight.
Focusing Only on the Gap
Width alone does not determine severity. Tension and function are equally important.
Using Forceful Movements
Strong crunches or aggressive movements during a check can place unnecessary strain on the healing tissue.
What to Do After Checking
If your self-check suggests a separation, the next step is not to avoid movement but to approach it with the right strategy. Guided rehabilitation focuses on restoring control, building strength, and improving how your body manages pressure.
This includes learning how to activate your deep core, adjusting movement patterns, and progressing exercises safely over time.
What Recovery Looks Like
With a structured plan, most individuals see improvement in both function and tissue quality. You may notice better control during daily tasks, reduced discomfort, and increased confidence in your movement.
Recovery is gradual and depends on consistency. It is not about quick fixes but about building a strong and reliable foundation for your body.
Conclusion
Checking for abdominal separation is a valuable step in understanding your postpartum recovery. It gives you insight into how your core is functioning and whether it needs support. While a self-check can provide initial guidance, a professional assessment ensures accuracy and a clear path forward. With the right approach, you can restore strength, improve stability, and return to your daily activities with confidence. The next step is to book an assessment, gain clarity on your condition, and begin a structured plan tailored to your body and your goals.
