# Diastasis after childbirth can be managed at home too
Pregnancy and childbirth are an extraordinary test for the female body. The uterus expands, the abdominal wall stretches, hormones alter the firmness of connective tissue – and the result can be a condition that is still far too rarely discussed. Diastasis recti after childbirth affects, according to various estimates, up to 60% of women in the immediate postpartum period, and in some of them it persists for months or even years. Yet many mothers first hear this term only when their gynaecologist or physiotherapist tells them they have "separated muscles."
So what exactly is diastasis? It is a separation of the rectus abdominis muscles along the midline – the so-called linea alba, a fibrous band that connects both muscles. During pregnancy, this connective tissue naturally loosens and stretches to make room for the growing belly. The problem arises when, after delivery, the muscles either fail to return to their original position on their own, or when the gap is so large and the linea alba so lax that it can no longer fulfil its stabilising function. The result is not merely an aesthetic issue – although the protruding centre of the abdomen troubles many women – but above all a functional deficit that can manifest as back pain, pelvic floor instability, a sense of weakness in the trunk, or even digestive problems.

How to find out whether you have diastasis
The good news is that a basic screening test can be performed at home, without any equipment. Lie on your back, bend your knees and place your feet flat on the floor. Place one hand behind your head and lay the fingers of the other hand horizontally across the centre of your abdomen, roughly at the level of the navel. Then slowly lift your head and shoulders – as at the start of a classic crunch – and pay attention to what you feel beneath your fingers. If you feel a gap into which your fingers partially "sink," along with soft, almost absent resistant tissue in the middle, this may indicate the presence of diastasis. A gap of approximately two fingers' width or more is considered clinically relevant, although width alone is not the only indicator – the depth and tension of the tissue are also important.
It is essential to emphasise, however, that the home test serves only as an initial orientation. A definitive diagnosis should always be made by a specialist – ideally a physiotherapist specialising in pelvic floor health or postpartum women's health. Ultrasound can measure the width of the separation more precisely and also assess the quality of the linea alba itself, which is crucial for planning rehabilitation. The Czech physiotherapy community is increasingly engaged with this topic, and specialist facilities are becoming available beyond major cities.
When should you be cautious about performing the test? In the first six weeks after delivery, the body is still healing intensively and any testing should be approached with care. Many experts recommend the first check-up after the six-week postnatal period has passed, and ideally as part of a visit to a physiotherapist rather than as a self-help experiment in the living room.
What to do about diastasis at home: movement that helps and movement that harms
Once diastasis has been confirmed, the question that troubles almost every affected mother arises: what now? The answer depends on the severity of the condition, but there are many things that can be addressed at home – and equally many things that women with diastasis should definitely not do, even though this may come as a surprise.
Let us start with what is harmful. The conventional gym, as most of us know it, can be a genuine trap for a woman with unresolved diastasis. Exercises such as classic sit-ups, a full plank position, or heavy barbell squats can worsen the separation, because they increase intra-abdominal pressure and overload the weakened linea alba. Women should also be mindful of everyday activities – getting out of bed by sitting straight up rather than rolling onto one side first, carrying heavy loads on one side of the body, or coughing and sneezing without consciously engaging the deep stabilising system.
On the other hand, there is a whole range of physical activities and conscious habits that support healing. The foundation is working with the deep spinal stabilising system – that is, the diaphragm, the pelvic floor, the deep back muscles, and the transversus abdominis. The transversus abdominis is the key player in diastasis rehabilitation, because it functions as a natural corset and helps to tension the linea alba again. Exercises that engage it are gentle, subtle and perhaps visually unimpressive – but they deliver results.
Specific exercises most commonly recommended by specialists in the early phase of rehabilitation include:
- Breathing exercises with conscious abdominal engagement – gently drawing the navel towards the spine on the exhale
- Pelvic floor activation – Kegel exercises in various positions
- Heel slides – slowly sliding the heel along the mat while lying on your back, maintaining a neutral pelvic position
- Dead bug in a modified, safer version without full range of motion
Alongside exercise, overall body care also plays a role. Quality sleep and an anti-inflammatory diet rich in collagen, vitamin C and zinc support the healing of connective tissue. Collagen is the fundamental building block of the linea alba, so it makes sense to focus on its intake – whether through diet (bone broths, fish, eggs) or quality supplements. Hydration is equally important, as connective tissue requires adequate fluid to function properly.
As physiotherapist and pelvic floor specialist Kaisa Tuominen puts it: "Diastasis is not a diagnosis that condemns you to a lifetime of limitations. It is a challenge that forces you to know your body more deeply than you ever had to before."
A practical aid in home rehabilitation can also be a special supportive belt or diastasis brace, which mechanically draws the abdominal muscles together and reduces the load on the linea alba during everyday activities. These aids are not a substitute for exercise, but they can be a useful supplement especially in the first few weeks, when the body is still very sensitive. When choosing one, it is advisable to consult a physiotherapist about which type of belt is appropriate for the specific situation.
How long does diastasis treatment take
This is a question with no simple answer – and every woman who has encountered diastasis knows this well. The length of rehabilitation depends on many factors: the width and depth of the separation, the quality of the linea alba, whether it is a first or subsequent birth, the woman's age, her physical condition before pregnancy, and how soon and how systematically she begins to address the problem.
Generally speaking, mild diastasis (a separation of up to three centimetres with good tissue tension) often improves significantly with proper rehabilitation within three to six months. More severe cases may require a year or longer, and in some women – particularly those who have had multiple pregnancies or in whom the linea alba is permanently damaged – conservative treatment may not achieve full effect, and surgical correction becomes an option. However, this is indicated only in truly exceptional cases and should always be preceded by at least six months of physiotherapy.
It is important not to be discouraged by slow progress. The postpartum body undergoes enormous regeneration, and connective tissue is among the slowest to heal. A study published in the Journal of Orthopaedic & Sports Physical Therapy showed that women who completed a structured rehabilitation programme focused on the deep stabilising system achieved statistically significant improvements in diastasis width and pelvic floor function – but results came gradually, not overnight.
One of the most common mistakes observed by specialists is that women begin exercising, notice improvement after a few weeks, and then discontinue rehabilitation. Yet diastasis can return – or stagnate – if a woman does not develop long-term movement habits and does not work on correct movement patterns in everyday activities. Diastasis rehabilitation is not a sprint, but rather a marathon with a variable pace.
Consider a thirty-year-old mother of two who, after her second birth, discovered she could not breathe properly into her abdomen and felt a strange pressure in the centre of her trunk with every cough. After visiting a physiotherapist, she received her diagnosis: four-centimetre diastasis with significantly reduced linea alba tension. She began exercising at home for ten to fifteen minutes every day, adjusted her diet, learned how to get out of bed correctly, and after seven months the separation had reduced to two centimetres with markedly improved tissue tension. Today, a year and a half after giving birth, she exercises without restriction – but still consciously, still attentive to what is happening in her body. Her story is not exceptional. It is typical of women who approach diastasis with patience and knowledge.
The world of postpartum women's health care is fortunately changing. More and more gynaecologists, midwives and paediatricians are highlighting diastasis as a topic worthy of attention, rather than as "a normal part of motherhood that will resolve on its own." Organisations such as Pelvic, Obstetric and Gynaecological Physiotherapy in the United Kingdom, or the Czech Section of Physiotherapy in Healthcare, are actively educating both professionals and the general public. And with growing awareness comes a greater chance that women will receive help sooner – not only once back pain or pelvic floor problems have begun to significantly reduce their quality of life.
Diastasis after childbirth is not a life sentence. It is a challenge that, with the right approach – a combination of physiotherapy, conscious movement, nutritional care and patience – leads to significant improvement in the vast majority of women. And the first step? Stop ignoring it and find out exactly where your body is right now.
