After abdominal surgery, many people expect the recovery process to be linear: the wound heals, the pain decreases, and life slowly returns to normal. However, in some cases, an unexpected concern appears: a bulge in the midline of the abdomen, feeling weak when straining or persistent low back pain.
These signs may correspond to a rectal diastasis after abdominal surgery, a condition that is more common than is believed and that deserves an appropriate evaluation.
In the practice of Dr. Jennifer Gaona, a plastic surgeon in Bogotá with extensive experience in reconstructive and aesthetic abdominal surgery, it is common to see patients who consult with questions about whether these changes are normal or if they require treatment.
This article is designed to accompany you in this process of understanding: what is rectal diastasis after surgery, why it occurs, when it is expected and when you should seek specialized medical attention.
La rectus abdominis diastasis is the abnormal separation of the two straight muscles of the abdomen, which are normally joined in the midline by a fibrous structure called Alba line. After abdominal surgery, this band may weaken, or lose tension, allowing muscles to move sideways.
It is important to understand that diastasis is not the same thing as a hernia. In the hernia there is a real defect, a “hole” through which internal tissues are produced. In diastasis, on the other hand, There isn't a hole, but rather a widening of the alba line. Even so, both conditions can co-exist, especially in patients who have had previous surgeries or a sustained increase in abdominal pressure.
Abdominal surgery involves incisions, tissue manipulation and sutures that, even if performed with the correct technique, can affect the integrity of the abdominal wall. Procedures such as laparotomy, C-sections, digestive surgery, or even a previous tummy tuck can weaken the linea alba.
Factors such as postoperative infections, poor healing, excessive wound tension, obesity, previous pregnancies or multiple surgeries increase the risk. Over time, that combination of weakened tissue and internal pressure promotes the onset of rectal diastasis after abdominal surgery.
The most visible sign is usually a bulge in the midline of the abdomen, which is most evident when coughing, getting out of bed or straining. Some people describe that their abdomen “opens” when it contracts or that it never manages to look flat despite exercise.
At the functional level, diastasis causes Core weakness, making everyday activities such as carrying objects, standing up without the help of your arms or maintaining an upright posture for long periods of time difficult. This lack of central support often results in chronic low back pain, feeling of instability and muscle fatigue.
In some cases, the alteration of the abdominal muscles affects coordination with the pelvic floor, favoring symptoms such as urinary incontinence when laughing, coughing, or exercising. These signs should not normalize and are a clear sign that the abdomen is not working properly.
Evaluation by a specialist is essential to confirm the diagnosis. The physical exam is usually performed with the patient at rest and during the abdominal contraction. A larger separation of 2 to 3 centimeters is usually considered clinically relevant, although the therapeutic decision does not depend only on the measure, but also on symptoms and functional impact.
In some cases, imaging studies, such as ultrasound or tomography, are requested to assess the integrity of the abdominal wall and rule out hidden hernias. This personalized evaluation allows us to define whether management should be conservative or surgical.
When diastasis is mild or moderate and there is no associated hernia, initial treatment is usually conservative. La specialized physiotherapy plays a central role, focusing on the activation of the abdominal transverse, diaphragmatic breathing and coordinated work with the pelvic floor.
These programs don't just seek to “close” the separation, but Improve core function, reduce pain and restore stability to the trunk. In many patients, this approach achieves significant improvement in symptoms, although it does not always completely eliminate the anatomical separation.
Surgery is considered when the rectal diastasis after abdominal surgery is extensive, symptomatic or associated with hernias. It is also an option when, despite physical therapy, functional weakness or pain persists.
There are different surgical techniques. La Abdominoplasty allows diastasis to be repaired by plicating muscles and, at the same time, correcting excess skin and sagging. In other cases, laparoscopic techniques or mesh repairs are used, especially when there are associated defects or risk of recurrence.
The choice of procedure depends on the patient's anatomy, surgical history and objectives. That's why a clear conversation with the surgeon about expectations, benefits, and risks is essential.
Recovery after surgery to correct the rectal diastasis after abdominal surgery it is a progressive process that requires perseverance, patience and medical follow-up. The goal is not only proper healing, but also to restore the function of the abdomen and prevent long-term relapses.
For the first two weeks, the priority is protect the suture of the Linea Alba. During this period it is normal to have swelling, a feeling of tightness and discomfort when moving. Pain control with the indicated medication, relative rest and gentle mobilization are essential.
It's important avoid any activity that increases intra-abdominal pressure, such as carrying weight, straining when standing up or making sudden movements. Even everyday actions such as coughing or laughing should be done with manual abdominal support to reduce strain on the repair.
La abdominal girdle plays a key role during the initial recovery. It provides external support, reduces feelings of instability and helps keep tissues in the proper position while they heal. Continuous use is generally indicated for the first 4 to 6 weeks, depending on the surgical technique and individual evolution.
Wound care is also essential. Keeping the area clean and dry, monitoring for signs of infection and going to medical check-ups on time makes it possible to detect and treat any complications early.
Between the second and sixth week, many patients can resume light activities, such as walking longer distances or performing simple household tasks. However, the return to work will depend on the type of work activity: sedentary jobs are usually resumed before those that involve physical effort.
La specialized physiotherapy usually starts at this stage. Its objective is to re-educate the core, improve muscle coordination and strengthen the abdomen in a safe way, without compromising surgical repair.
More intense exercise, including strength training, impact training, or sports, is usually postponed until approximately 12 weeks, always with medical authorization. The return should be gradual and guided, prioritizing technique and muscle control over intensity.
A hasty restart of exercise is one of the main causes of relapse, so respecting recovery times is a direct investment in the durability of the surgical result.
Once the initial phase of recovery is over, the focus is shifted to long-term protection of the abdominal wall. Surgery corrects diastasis, but maintaining the result depends largely on the patient's daily habits.
Maintaining a stable weight is one of the most important factors in preventing the recurrence of diastasis. Significant weight gain increases pressure within the abdomen and puts stress on the repaired alba line again.
Avoiding constipation, treating chronic coughs, and controlling habits that generate repeated straining also contribute to a sustained reduction in intra-abdominal pressure.
Strengthening the abdomen doesn't end with surgery. Exercise programs focused on transverse abdominal, diaphragmatic breathing and the pelvic floor they help maintain trunk stability and correctly distribute loads during movement.
This work should be progressive and, preferably, guided by physiotherapists with experience in post-surgical abdominal rehabilitation.
Learning to sit, stand and carry objects properly protects the repair in the long term. Flexing the knees, keeping the load close to the body and avoiding explosive movements without abdominal control reduces the risk of injuries and relapses.
Listening to the body's signals is key. Persistent pain, a bulging sensation, or scar changes should be a reason for medical consultation, even months or years after surgery.
No. Many cases improve with physical therapy and lifestyle changes. The surgery is reserved for large, symptomatic or hernia-associated diastases.
The girdle It doesn't correct diastasis on its own, but it provides support and relief during recovery, especially after surgery.
Yes, but they should be specific, guided exercises. Some traditional movements can worsen the separation if not done properly.
There is a low risk of recurrence, which increases if there is significant weight gain or intense efforts are resumed prematurely.
La rectal diastasis after abdominal surgery It's not just an aesthetic concern; it's a functional condition that can affect your posture, core strength, and daily well-being. Recognize symptoms in time and know When to seek specialized medical care makes the difference between living with chronic discomfort or recovering a stable, strong and functional abdomen.
Each operated abdomen has a different story. That's why Dr. Jennifer Gaona and her team address abdominal diastasis from a comprehensive and personalized evaluation, taking into account your previous surgeries, symptoms, goals and lifestyle.
This approach makes it possible to define the safest and most effective treatment, whether conservative or surgical, always prioritizing function, body harmony and the durability of the results.
