Key Takeaways
Diastasis recti is a separation of the abdominal muscles that commonly occurs during pregnancy
The condition affects up to 60% of pregnant women and can persist after childbirth
Symptoms include a visible bulge or ridge down the middle of the belly
Physical therapy and targeted exercises are the primary treatment approaches
Most cases improve with proper rehabilitation and time
Overview
Diastasis recti is a condition where the rectus abdominis muscles (your "six-pack" muscles) separate along the midline of your abdomen. This separation happens when the connective tissue between these muscles stretches and weakens.
The condition most commonly develops during pregnancy as your growing baby puts pressure on your abdominal wall. However, it can also occur in newborns, men, and women who have never been pregnant. The separation creates a gap that can range from a few centimeters to several inches wide.
About 35-60% of pregnant women develop diastasis recti during their pregnancy. The good news is that many cases improve naturally after delivery, though some people need targeted treatment to fully recover.
The connective tissue between your abdominal muscles is called the linea alba. When this tissue stretches too much, it loses its ability to hold the muscles together properly. Your muscles don't actually tear apart, but they move farther away from each other along the center of your belly.
Some people may not notice their diastasis recti right away. The separation can happen gradually over several months or even years in some cases. Understanding what is happening in your body helps you know when to seek help from a doctor.
Symptoms & Signs
Diastasis recti symptoms can vary from person to person. Some people notice obvious visual changes, while others may only feel functional differences in their core strength.
Primary Symptoms
Visible bulge or ridge that appears down the center of your belly, especially when sitting up or straining
Weak core muscles that make it hard to lift heavy objects or get out of bed
Lower back pain due to reduced abdominal support for your spine
Poor posture as your body compensates for weakened core muscles
The bulge may look like a ridge or a soft bump running down your belly. This happens because your abdominal muscles are no longer holding your belly in tight. The bulge is usually more noticeable when you tense your abdominal muscles or lean forward.
Weak core muscles can make everyday tasks harder than they should be. You might feel tired when standing for long periods or find it difficult to climb stairs. Some people feel unstable or off-balance because their body is not getting the support it needs from their core muscles.
Some people with diastasis recti also have lower back pain, but the separation may not be the cause. A healthcare professional can assess persistent pain and look for other possible causes.
When to Seek Care
You should contact a healthcare provider if you experience severe abdominal pain, persistent back pain, or if the separation seems to be getting worse over time. A healthcare provider can help determine whether your symptoms are related to diastasis recti or another condition.
When to Seek Immediate Care
Seek urgent medical care for severe or worsening abdominal pain, persistent vomiting, fever, a painful or firm bulge, or a bulge that cannot be pushed back. These symptoms are not typical of diastasis recti and may indicate another condition, such as a hernia complication.
Causes & Risk Factors
The primary cause of diastasis recti is increased pressure on the abdominal wall that stretches the connective tissue between your rectus abdominis muscles. This pressure most commonly comes from pregnancy, but other factors can contribute.
During pregnancy, hormones like relaxin soften your connective tissues to prepare for childbirth. Combined with the growing baby pushing against your abdominal wall, this creates the perfect conditions for muscle separation.
The hormone relaxin starts working early in pregnancy to loosen ligaments and connective tissue. This is helpful for childbirth but can make your abdominal muscles more likely to separate. The effect of relaxin combined with the weight of your baby creates stress on your belly muscles.
Age
Risk Factors
Factors associated with diastasis recti include age over 35, family history of connective tissue disorders, multiple pregnancies, carrying a large baby, reduced core strength, obesity, chronic coughing, and heavy lifting with poor form.
Genetics
Family history of connective tissue disorders increases likelihood
Lifestyle
Multiple pregnancies, carrying large babies, or poor core strength
Other Conditions
Obesity, chronic coughing, or heavy lifting without proper form

Diagnosis
Healthcare providers can usually diagnose diastasis recti through a simple physical examination. The process is straightforward and doesn't require expensive tests in most cases.
Medical History & Physical Examination
Your doctor will ask about your pregnancy history, symptoms, and any activities that worsen your condition. They'll examine your abdomen while you're lying down and sitting up to assess the separation. The provider will measure the width and depth of the gap between your abdominal muscles.
Diagnostic Testing
Physical finger test where the provider checks the separation width with their fingers
Ultrasound imaging to get precise measurements of the muscle gap and tissue thickness
CT scan or MRI in complex cases to evaluate deeper abdominal structures

Treatment Options
Treatment for diastasis recti focuses on strengthening your core muscles and improving functional movement patterns. Most people can see significant improvement with consistent, targeted exercises.
Conservative Treatments
Physical therapy with specialized exercises to retrain your deep core muscles
Breathing exercises that engage your diaphragm and pelvic floor muscles
Postural training to reduce strain on your abdominal muscles during daily activities
Physical therapy is usually the first treatment doctors recommend for diastasis recti. A trained physical therapist will teach you exercises that specifically target your deep core muscles. These exercises help your muscles work together again to close the gap between them.
Breathing exercises may sound simple, but they are very important for healing. Proper breathing helps activate your deep core muscles without straining your abdominal wall. Your physical therapist will show you how to breathe correctly during exercise and daily activities.
Advanced Treatments
Surgical repair (abdominoplasty) when conservative treatment fails after 12-18 months
Minimally invasive procedures using mesh or sutures for smaller separations
Combined approaches that address both muscle separation and excess skin
Diastasis recti treatment works best when guided by healthcare professionals.
Surgery is usually only considered when exercises and physical therapy haven't helped after many months. Most people improve without needing surgery if they stick with their exercise program. Your doctor will discuss whether surgery might be right for you based on your specific situation.
Living with the Condition
Managing diastasis recti requires patience and consistency with your treatment plan. Many people find that small daily changes make a big difference over time.
Daily Management Strategies
Focus on proper body mechanics when lifting, getting out of bed, or carrying objects. Avoid activities that cause your abdominal muscles to dome or bulge outward. Practice good posture throughout the day and use supportive garments if recommended by your healthcare provider. Maintain a healthy weight to reduce pressure on your abdominal wall.
Wearing supportive clothing can help reduce symptoms while you recover. Special belly bands or compression garments can make daily activities feel easier. These supports work best when combined with exercises and proper movement habits.
Exercise & Movement
Start with gentle breathing exercises and basic core activation before progressing to more challenging movements. Walking, swimming, and modified yoga can be beneficial for overall fitness. Proper rehabilitation takes time and consistency. Exercises such as crunches, planks, and resistance training may need to be modified based on your symptoms, technique, and current ability. A physical therapist can help you progress safely.
Exercise should feel gentle and controlled when you have diastasis recti. Visible doming may mean that an exercise is currently too difficult to control. Modify the movement or ask a physical therapist to assess your technique. Talk to your physical therapist before starting any new exercise program to make sure it's safe for your condition.
Consistency with exercise is more important than doing intense workouts. Doing your exercises a little bit every day is better than doing a lot of exercise once a week. Improvement varies among individuals and may take weeks or months. Progress depends on factors such as symptoms, function, the degree of tissue change, and the exercise program.
Prevention
Maintain proper form during pregnancy exercises and avoid activities that strain your abdominal muscles
Practice good posture and body mechanics during pregnancy and daily activities
Strengthen your core before pregnancy if possible, focusing on deep stabilizing muscles
Control weight gain during pregnancy according to your doctor's recommendations
Use proper lifting techniques and avoid heavy lifting when your abdominal muscles are weakened
Reducing the risk of diastasis recti involves consistent healthy movement habits over time.
Staying active before and during pregnancy can support overall strength and function, but diastasis recti is common during pregnancy and cannot always be prevented. Ask your healthcare provider which exercises are appropriate for you. Talk to your doctor about safe exercises you can do before becoming pregnant.
Use comfortable, controlled movement and appropriate lifting technique during pregnancy. Routine twisting or lifting does not need to be avoided unless it causes symptoms or your healthcare provider recommends restrictions. Using proper lifting techniques, like squatting instead of bending at your waist, protects your growing belly.
After pregnancy, returning to core exercises gradually helps your muscles heal properly. Starting too soon with intense exercise can make separation worse instead of better. Work with your doctor to know when it's safe to begin exercise after you give birth.
Frequently Asked Questions
Many cases improve naturally within 6-12 months after delivery, especially with mild separations. However, larger gaps or persistent symptoms usually need targeted treatment to fully resolve.
Can I exercise with diastasis recti?
Yes, but you need to choose the right exercises. Focus on gentle core activation and breathing exercises first, then progress gradually under professional guidance. Avoid movements that cause your abdomen to dome outward.
No, while pregnancy is the most common cause, diastasis recti can also occur in men, children, and women who have never been pregnant. Factors like obesity, chronic coughing, or improper exercise technique can contribute to the condition.
Recovery time varies greatly depending on the severity of separation and your commitment to treatment. Mild cases may improve in 6-8 weeks with proper exercises, while severe cases can take 6-12 months or longer to see significant improvement.
Surgery may be considered when significant symptoms persist despite appropriate conservative care, when a hernia is also present, or when a specialist determines that repair is appropriate. The decision is individualized and is not based on gap width alone. Surgery is usually considered only after appropriate conservative treatments have been tried.
