Abdominoplasty: 5 important facts about the procedure

Although abdominoplasty is often seen simply as a way of removing excess abdominal skin, the procedure has a broader purpose. As techniques have evolved, surgery has become an important option for rebuilding body contours, especially after pregnancy, substantial weight fluctuations or intensive weight loss.

According to Dr Flávia Bonato, a plastic surgeon who is a member of the Brazilian Society of Plastic Surgery, the International Society of Aesthetic Plastic Surgery (ISAPS) and the Brazilian Association of Aesthetic Plastic Surgery (BAPS), modern abdominoplasty assesses the entire abdominal structure, making it possible to address changes that go beyond surplus skin.

“Many patients come to the clinic believing that excess skin is the only issue. In reality, 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 must take all these structures into account for the outcome to be harmonious,” she explains.

Here are five facts that can help you understand the procedure more clearly.

1. The procedure can correct separation of the abdominal muscles

One of the most common changes following pregnancy or major weight variation 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 often offers not only aesthetic benefits but functional ones as well. Many patients report improved core stability and body awareness after surgery,” says Dr Flávia Bonato.

2. Abdominoplasty is not always intended for weight loss

Despite its frequent association with losing weight, abdominoplasty is not a weight-loss procedure. “In practice, the operation is intended to remove excess tissue and improve body contours in patients who are already close to their desired weight. It is even more common after weight loss,” says the doctor.

According to the plastic surgeon, this is increasingly common among people who have experienced substantial weight loss, including through the use of weight-loss medication, and are left with excess skin and abdominal laxity.

Dr Flávia Bonato stresses that surgery should not be considered a substitute for health measures such as a balanced diet and regular exercise. Results from the technique tend to be 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 remodelling is generally enhanced when it is combined with liposuction,” says Dr Flávia Bonato.

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

It is also possible to pair abdominoplasty with other procedures. “Today, we can combine abdominoplasty, for example, with technologies from the IgniteRF platform, such as Quantum and Morpheus, ultrasonic liposculpture and direct intramuscular fat injection,” says the doctor.

Dr Flávia Bonato notes that surgical planning considers the body as a whole, taking account of the balance between different structures. “Simply removing skin is not enough. We need to assess proportions, contours and volumes 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 treated. The plastic surgeon explains that, in traditional abdominoplasty, the abdominal skin is pulled down after excess tissue is removed. Consequently, the navel must be brought through 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 attracts 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 requires 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 for concerns 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, above all, whether the patient has concerns above the navel,” says Dr Marcelo Rudy.

According to Dr Flávia Bonato, individualisation is one of the foundations of modern plastic surgery. “The biggest operation is not always the best operation. Successful treatment depends on identifying precisely what each patient needs. There are situations in which smaller procedures deliver 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 medical history, the presence of diastasis, skin quality, body weight, lifestyle habits and the patient’s expectations directly affect surgical planning.

“Another important consideration 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.

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

Surgery is only one part of treatment. According to Dr Flávia Bonato, recovery also relies on the body’s ability to promote healing. Nutritional adjustments and, where necessary, support from a nutritionist may therefore be recommended 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, giving the patient back comfort and harmony,” she concludes.
