Liposuction

No. Liposuction treats subcutaneous fat deposits and changes contour; it is not an obesity treatment or a substitute for a weight-loss plan. Brazilian CFM Resolution 1.711/2003 explicitly states it should not be indicated for weight loss.

Assessment considers what is causing the volume: fat under the skin, visceral fat, excess skin or abdominal wall changes. Liposuction does not reach fat inside the abdomen around the organs.

Nor can a specific weight loss be promised. Body weight and contour change are different measures, and the early recovery period includes swelling.

If substantial weight loss is still planned, addressing that first may be more appropriate. In patients with stable weight, localised deposits and suitable skin, surgery may improve proportions within its limitations and individual risks.

Liposuction reduces fat tissue in the area but does not prevent new fat accumulation or future contour changes. Remaining cells may enlarge with weight gain.

It is also incorrect to explain the result by saying adults never produce new fat cells. A study of adipose tissue biology found turnover of approximately 10% of fat cells each year, even with a relatively stable total number under certain conditions. This does not mean the treated area will necessarily return to its previous volume.

A small randomised trial involving 32 womeninvestigated fat restoration and redistribution after liposuction. It reinforces that removing fat from one area does not eliminate the body's regulation of adipose tissue, but cannot predict exactly what will happen to each patient.

In practice, maintaining habits and a relatively stable weight helps preserve the outcome. Surgery changes local fat distribution; it does not make the area immune to body changes.

The limit is not the same for every patient and should not be based on the number of areas alone. Weight, health, treated area, technique, operating time and combined procedures must be considered.

In Brazil, CFM Resolution 1.711/2003 states that aspirated volume should not exceed 7% of body weight with the infiltrative technique or 5% with the non-infiltrative technique, and the area should not exceed 40% of body surface area. The regulation advises against reaching both maximum parameters together or combining procedures near these limits; specifically justified exceptions are provided for in a fully equipped hospital.

An important technical distinction: under this resolution, aspirated volume means the supernatant material collected. This is not automatically equivalent to total aspirate, including all fluids, used in some international references.

These are planning limits, not removal targets or guarantees of safety. Individual indications may require much smaller volumes. Extensive treatment may be better staged. At the consultation, I explain estimated volume and which areas may be treated together.

High-definition liposuction aims to accentuate muscular contours through selective fat treatment. It does not build muscle strength or replace training; the result is a surgical contour change.

It may involve technologies such as ultrasound, but high definition is not synonymous with a particular device. Selection depends on anatomy, the team's experience and the desired degree of definition.

Good skin quality and suitable body composition help planning. Visceral fat, substantial excess skin and expectations of a permanently defined abdomen may limit suitability. Definition should also be assessed in motion and with the body relaxed.

The original Hoyos and Millard publication described a demanding technique with a learning curve and possible complications. It should not be used to claim universal superiority over conventional liposuction. Excessive definition, irregularities and outcomes that do not adapt to weight changes are issues to discuss.

Before choosing, we discuss the appearance you consider appropriate and less defined alternatives.

Liposuction removes fat, not excess skin. Retraction depends on tissue elasticity and quality, as well as the amount and distribution of the volume treated.

With good elasticity, skin may adapt to the new contour. If significant laxity already exists, removing fat may make the excess more apparent. Age, pregnancies and major weight fluctuations inform assessment, but examination is decisive.

In some cases, appropriate treatment includes skin removal, such as a tummy tuck or body lifts. Technologies intended to tighten skin can be discussed for specific indications, but should not be presented as guaranteed substitutes for skin removal when excess is substantial.

No single percentage of skin retraction applies to every device or patient. Planning must clarify what liposuction alone may improve, what will probably remain and whether another procedure may be needed.

Gluteal fat grafting uses the patient's own fat to change buttock volume and contour. Some grafted fat may be reabsorbed, and retention varies; injected volume cannot be promised to equal final volume.

Planning respects tissue capacity and safety. Extra fat should not automatically be grafted to compensate for reabsorption. A second stage may sometimes be considered after assessing the outcome.

The main concern is fat embolism, a potentially fatal complication. The joint statement by plastic surgery societies in 2022 advocates injection only into subcutaneous tissue, above the gluteal fascia, and the use of real-time ultrasound to monitor cannula position during injection. These measures reduce risk; they do not guarantee freedom from complications.

I do not use a historical mortality rate as though it represents your current individual risk. Technique, team, setting, volume and patient selection need individual discussion.

Recovery includes specific instructions about pressure on the area, positions and activities. Stable weight helps assess the volume achieved but does not eliminate biological variation in graft integration.
