Abdominoplasty: 5 facts about the procedure and body contour

Although abdominoplasty is often linked solely with removing surplus skin from the abdomen, the procedure has a broader purpose. As techniques have developed, the operation has become an important option for restoring body contours, particularly after pregnancy, substantial weight fluctuations or significant weight loss.

According to Dr Flávia Bonato, a plastic surgeon and member of the Brazilian Society of Plastic Surgery (SBCP), the International Society of Aesthetic Plastic Surgery (ISAPS) and the Brazilian Association of Aesthetic Plastic Surgery (BAPS), modern abdominoplasty assesses the abdominal area as a whole and can address changes that extend beyond excess skin.

“Many patients arrive at the clinic believing that excess skin is the only issue. In fact, there is often a combination of factors, such as separation of the abdominal muscles, changes to the waistline, laxity in the deeper tissues and excess localised fat. Treatment needs to take all these structures into account for the result to be harmonious,” she explains.

Here are five facts that offer a clearer understanding of the procedure.

1. Abdominoplasty can correct separation of the abdominal muscles

One of the changes most commonly seen after pregnancy or major changes in weight is abdominal diastasis, a condition in which the rectus abdominis muscles separate. This can leave the stomach protruding even in people with a low body-fat percentage or those who exercise regularly.

“During abdominoplasty, the surgeon can perform muscle plication, a technique that repositions these muscles and helps restore firmness to the abdominal wall. Correcting diastasis generally offers not only aesthetic benefits but functional ones as well. Many patients report improved trunk stability and body awareness after surgery,” says Dr Flávia Bonato.

2. The aim is not always weight loss

While it is frequently connected with losing weight, abdominoplasty is not a weight-loss procedure. “In practice, the operation is indicated to remove excess tissue and improve body contour in patients who are already close to their desired weight. It is actually more common after weight loss,” the doctor states.

According to the plastic surgeon, this is increasingly common among people who have experienced considerable weight loss, including after using weight-loss medication, and have been left with excess skin and abdominal laxity.

Dr Flávia Bonato stresses that surgery should not be regarded as an alternative to health measures such as a suitable diet and regular exercise. Results from the technique are generally more satisfactory when the patient’s weight is already stable and they wish to address changes that lifestyle adjustments have not corrected.

3. Abdominoplasty is often combined with liposuction

A common question is whether the surgery removes fat. “Although small amounts can be removed along with the excess skin, body reshaping is generally enhanced when it is combined with liposuction,” says Dr Flávia Bonato.

This combination makes it possible to address laxity and deposits of localised fat at the same time. “The advantage of combining abdominoplasty with liposculpture is better treatment of the body contour, bringing out the waist more clearly and creating a more attractive silhouette,” highlights Dr Marcelo Rudy, a plastic surgeon and member of the Brazilian Society of Plastic Surgery.

Abdominoplasty can also be paired with other procedures. “We can currently combine abdominoplasty, for example, with technologies from the IgniteRF platform, such as Quantum and Morpheus, with ultrasonic liposculpture and with direct intramuscular fat injection,” the doctor says.

Dr Flávia Bonato notes that surgical planning considers the body in its entirety, taking the balance between different structures into account. “Simply removing skin is not enough. We need to assess proportions, contours and volumes in order to achieve a natural, balanced result.”

4. The navel is usually repositioned

One aspect of the operation that often surprises patients is how the navel is managed. The plastic surgeon explains that, in traditional abdominoplasty, the abdominal skin is pulled downwards once the excess has been removed. Consequently, the navel must be brought out again in a new anatomical position.

“That is why the final appearance of the navel is an important stage of surgical planning. The navel is one of the details that draws the most attention in the final result. There are now techniques designed to create an understated, natural appearance that is proportionate to the abdomen,” explains Dr Flávia Bonato.

5. Not every patient needs a full abdominoplasty

Although the traditional version is the best known, there are different forms of the procedure, including mini-abdominoplasty. “Mini-abdominoplasty is indicated when complaints are below the navel. The choice between it and conventional surgery depends on the amount of skin that needs to be removed, whether the patient has diastasis and, most importantly, whether the patient has concerns above the navel,” says Dr Marcelo Rudy.

According to Dr Flávia Bonato, tailoring treatment to the individual is one of the foundations of modern plastic surgery. “The largest operation is not always the best operation. Successful treatment depends on identifying exactly what each patient needs. There are situations in which smaller procedures provide excellent results precisely because they respect the anatomical characteristics of that case,” she says.

Important care before and after surgery

Despite technical advances, abdominoplasty should always be recommended only after a detailed medical assessment. Dr Flávia Bonato also explains that clinical history, the presence of diastasis, skin quality, body weight, lifestyle habits and the patient’s expectations all directly influence surgical planning.

“Another important aspect is the patient’s nutritional status before and after surgery. Adequate protein intake deserves particular attention, as these nutrients provide the amino acids needed for collagen synthesis, tissue repair and healing,” says the doctor.

Medical follow-up is therefore essential. “Patients who have undergone major weight-loss processes, including those who have used weight-loss medication, may have insufficient protein intake or loss of muscle mass, which must be identified and corrected before the procedure. After the procedure, protein supplementation may be indicated, depending on the patient,” she explains.

Surgery is only one part of treatment. Dr Flávia Bonato says that recovery also depends on the body’s ability to promote healing. Nutritional adjustments may therefore be recommended, as well as support from a nutritionist where necessary, to optimise protein intake and aid post-operative recovery.

“Modern plastic surgery seeks naturalness and proportionality. The aim is not to transform the body completely, but to restore structures that have been altered by time, pregnancy or weight loss, returning comfort and harmony to the patient,” she concludes.
