Can you fix diastasis recti — even years later?” The short answer is yes. But the more useful answer depends on what you actually mean by “fixed.”
As awareness of diastasis recti (DR) has grown, so has the confusion surrounding it. Our goal is to demystify DR with evidence-based, easy-to-understand information you can actually use, whether you’re healing yourself or working with clients.
Read on to learn:
- What diastasis recti (DR) is
- What causes DR
- How to check yourself (or a client) for DR
- What “fixing” DR actually means
- The factors that influence how quickly DR heals
- What you can do to support healing at any stage postpartum
Quick Answer: Yes, you can heal diastasis recti at any point postpartum — even years later — because the linea alba is made up of collagen and, like other soft tissues in the body, it can remodel with the right inputs. But “fixing” DR is more nuanced than most people think. The common goal of “closing the gap” has two problems: first, everyone has some degree of natural separation, so there is no true baseline to close back to; and second, research suggests that the tension you can generate in the linea alba is a more telling indicator of recovery than gap width alone. How quickly healing progresses depends on several factors — some of which are within your control (like alignment, breathing mechanics, and core recovery work), and some that are not (like age and genetics). The real measure of successful healing is a strong, functional core that supports the activities that matter to you.
What Diastasis Recti Is
Diastasis recti is a wider-than-usual separation between the left and right sides of the rectus abdominis (“6-pack”) muscle. The word “diastasis” means separation, and “recti” refers to the rectus abdominis. One commonly used definition is a separation of 2.7 cm (about 2 finger-widths) or greater at the umbilicus (Rath et al., 1996).
DR can often present as a “torpedo-like” protrusion in the belly, most visible during movements that engage the abdominal muscles, such as in the image below.
What Causes Diastasis Recti
The primary cause of DR is consistent and excessive intra-abdominal pressure (IAP). There are several factors that can lead to elevated IAP, which is why DR can occur in anyone — male and female alike. One completely normal and necessary cause is the growing belly during pregnancy. As the belly grows, it increases outward pressure on the abdominal wall, which thins and stretches the connective tissue running down the midline of the body, called the linea alba. This weakens the linea alba, which causes the left and right sides of the rectus abdominis to move further apart.
Because DR is a natural part of pregnancy, everyone will have at least some degree of DR in the immediate aftermath of labor. Healing rates vary widely by individual based on several factors. This is what we’ll get into now.
How to Check Yourself for Diastasis Recti
Before beginning any recovery work, it helps to have an accurate picture of your starting point by performing a DR check. This assessment measures two things: width (how many finger-widths fit between the ridges of the rectus abdominis) and depth (how the tissue feels when you press down on it — from shallow and springy to soft and deep). Depth is actually the more telling indicator of severity.

Note: We recommend waiting until you are at least 6 weeks postpartum to perform this assessment, as everyone will have some degree of DR in the weeks following delivery.
What Does it Mean to “Fix” or “Heal” Diastasis Recti?
Most people, when they think about healing DR, are thinking about “closing the gap.” There are a couple of significant problems with that framing.
1. You don’t know what your pre-pregnancy “gap” was.
From an anatomical standpoint, there has always been a gap between the left and right sides of your rectus abdominis. We are not born fused together. Rather, we are designed to be pliable and move in three dimensions. Because most people only become aware of their gap after learning it has widened during pregnancy, there is no baseline to compare it to. “Closing the gap” is therefore neither an accurate nor a measurable goal.
2. The “gap” isn’t the ONLY important characteristic that defines DR.
As discussed in the articles linked above on how to check for DR, newer research shows that how much tension you can generate in the linea alba (or the “depth” of your gap) is a more telling indicator of the severity of your DR than the width of your gap. Put simply, if your core is strong and functional, and you don’t have pain, then the width of your gap matters very little.
As an illustration, watch the quick DR video demo below. In this case, you can clearly see the gap width. However, this individual can generate great “tension” in her linea alba tissue and has no pain. Therefore, this is not a problematic case of DR.
The bottom line: the goal is to develop a strong, capable core that supports the activities that matter to you — whether that’s picking up your child without pain or keeping up with your grandkids at the park. Successful healing is marked by satisfaction with your quality of life, not by achieving a certain number on a subjective assessment.
Factors that Influence DR Healing
Several factors impact how quickly and completely DR heals. Some are within your control; others are not.
- Alignment: The positions in which you orient and move your body directly impact how your deep core functions. Pregnancy often causes alignment shifts that can persist into the postpartum period, altering how the core recruits and fires. The more you can learn to move in neutral alignment, the more efficiently the linea alba tissue can heal.
- Breathing: The way you breathe significantly affects your core strength and function. Pregnancy-related alignment changes and weight gain often alter breathing patterns, which affects how much the core works. Learning 360° Breathing mechanics is one of the most meaningful steps you can take to expedite healing.
- Physical Activity: The more active you are, the more quickly your deep core structures tend to recover their strength and control.
- Degree of Core Recovery Work: Deliberately strengthening your deep core with progressive, specific postpartum recovery work accelerates healing far more than general activity alone.
- Age: The linea alba is made up of collagen, and collagen production begins to decline after age 25, with a more significant drop after 40. The older you are, the more time healing may take.
- Genetics: The characteristics of your soft tissues, including your collagen and skin elasticity, are influenced by genetics. Looser tissue may, by nature, mean a longer recovery timeline.
- Diet: Since the linea alba is primarily composed of collagen, what you eat directly affects healing. Collagen-rich foods can support tissue recovery, while a diet higher in processed foods can increase inflammation and slow it.
- Pregnancy Weight Gain: The more weight gained during pregnancy, the more the tissues are stretched and stressed, which affects both the degree and speed of recovery.
Take Your DR Knowledge Further
Understanding DR is one thing. Knowing how to systematically guide clients through recovery is another. The ProNatal Fitness Pre & Postnatal Fitness Specialist Certification teaches you a comprehensive Core Recovery Protocol to take clients through that will help them heal DR and rebuild a strong, functional core from the inside out, regardless of how long ago they gave birth.
Frequently Asked Questions About Healing Diastasis Recti
Can DR heal on its own without targeted exercise? Some natural remodeling of the linea alba can occur in the weeks following delivery, but research suggests that deliberate, progressive core recovery work is what drives meaningful healing. The linea alba is a tensile tissue, which means it needs to be loaded through resistance training in various planes of motion to fully remodel. General activity alone is unlikely to produce the same results as a structured core recovery approach.
How long does it take to heal diastasis recti? There is no universal timeline. Healing rate depends on several individual factors, including age, genetics, activity level, alignment, breathing mechanics, and the degree of separation. Some people notice significant improvement within a few months of consistent core recovery work; others take longer. What matters most is that healing is possible at any stage — even years postpartum — with the right approach.
Does the gap ever fully close? As stated above, from an anatomical standpoint, everyone has some degree of natural separation between the left and right sides of the rectus abdominis. We are not born fused together. Most people simply never measured their gap before pregnancy, so there is no true baseline to compare against. “Closing the gap” is therefore neither well-defined nor particularly useful as a goal. The more meaningful indicator of recovery is the tension you can generate in the linea alba, not the width of the gap itself. Many people develop a strong, fully functional core without achieving a specific gap measurement, and live without pain or limitation as a result.
Can you have DR without knowing it? Yes. DR does not always produce obvious symptoms. Some people have a measurable gap with no pain, no visible coning in the belly, and no functional limitations. This is why the depth assessment matters — a wide gap with good linea alba tension may be far less problematic than a narrower gap with poor tissue integrity.
Can DR come back after healing? It can, if the conditions that drove it in the first place return. Consistent and excessive intra-abdominal pressure is the primary driver of DR, so managing IAP through good alignment, breathing mechanics, and smart exercise programming is important for long-term recovery. This is as relevant for fitness professionals coaching clients as it is for individuals managing their own recovery.
