What Happens to Fat Cells After Liposuction?
If you’re considering liposuction, it’s important to understand how the procedure works and what happens to your body afterward – particularly when it comes to the fat cells that are removed. This article draws on clinical insights from Dr Mark Kohout, a specialist plastic surgeon based in Sydney, to explain what happens to fat cells after liposuction and what patients can realistically expect from the procedure.
A common question many patients ask is: “What happens to the fat cells that are taken out during liposuction – and can they come back?” Let’s take a closer look at what liposuction involves and clarify what really occurs during and after fat removal.

Understanding Liposuction
Liposuction is a surgical technique used to remove fat from specific areas of the body. Many individuals seek this procedure when certain regions – such as the abdomen, flanks, thighs, or upper arms – do not respond to regular diet and exercise.
There are several methods of liposuction, but the two most common are:
Traditional Liposuction
In traditional liposuction, Dr Mark Kohout makes small incisions in the targeted area and inserts a thin, hollow tube (cannula). Fat cells are loosened and removed using controlled suction. This method allows for the physical extraction of subcutaneous fat in areas that may be resistant to lifestyle changes alone.
Laser-Assisted Liposuction
Laser-assisted liposuction works similarly but uses laser energy to first liquefy fat before it is suctioned out. The laser technique can allow for smaller incisions and may result in less bruising and swelling post-operatively. In some cases, Dr Mark Kohout may perform this under local anaesthetic rather than general anaesthesia, depending on the extent of the treatment and the individual’s suitability.
Who Is a Candidate for Liposuction?
Liposuction is best suited for individuals who are close to their ideal body weight but have specific areas of localised fat that do not respond to lifestyle measures. It is not a treatment for obesity or a substitute for weight loss. A consultation with Dr Mark Kohout, specialist plastic surgeon, can determine whether liposuction is an appropriate option based on your individual goals and health profile.
Before and After Liposuction Patients
Types of Fat
There are three main types of fat cells in the human body: white, brown, and beige. White fat, the most abundant, stores energy, insulates, and protects organs. Brown fat burns energy to generate heat, primarily in newborns and hibernating animals. Beige fat, an intermediate type, can behave like either white or brown fat depending on the situation
What Happens to the Removed Fat Cells?
Fat cells that are removed during liposuction are permanently extracted from the body. Once removed, they do not regenerate. However, this does not mean that the body is incapable of storing fat in the future.
After liposuction, the number of fat cells in the treated area is reduced. However, remaining fat cells – both in the treated area and in other areas of the body – can still expand if overall caloric intake exceeds energy expenditure. In other words, while the treated areas may have fewer fat cells, weight gain can still occur elsewhere if lifestyle habits are not maintained.
Differences Between Fat Cell Size vs. Number
It is important to distinguish between fat cell size and number. Liposuction physically reduces the number of fat cells in targeted areas. In contrast, weight loss through diet and exercise primarily reduces the size of fat cells, not their number. This distinction helps explain why liposuction offers a contouring benefit that may not be achievable through lifestyle changes alone.
Can the Body Produce New Fat Cells?
While the body typically does not replace fat cells that have been removed, in rare cases of significant weight gain, new fat cells (a process called hyperplasia) can form. This makes long-term weight maintenance an important consideration after undergoing liposuction.
How the Body Responds After Fat Removal
Following liposuction, the body begins a healing process. Swelling and fluid retention are common in the initial weeks. The lymphatic system helps clear out cellular debris, and some firmness or scar tissue may develop temporarily. Over several months, the treated areas generally settle into their new shape as the tissues adjust.
Role of Fat Cells in the Body
Fat cells, or adipocytes, play more than just a cosmetic role. They store energy, help regulate temperature, and produce hormones involved in metabolism and inflammation. While liposuction can help reshape the body, it’s important to maintain an appropriate amount of body fat for overall health and physiological balance.
Does Fat Return to Other Areas?
A common misconception is that fat will “move” to other parts of the body after liposuction. In reality, fat distribution is influenced by genetics, hormones, and overall weight gain or loss. Liposuction does not cause fat to shift to new areas, but untreated areas with more fat cells may appear more prominent if weight gain occurs post-surgery.
Risks and Considerations
As with any surgical procedure, liposuction carries risks. These may include bruising, swelling, temporary numbness, uneven contours, or skin irregularities. Infections and complications from anaesthesia are less common but possible. Understanding these risks is an important part of the decision-making process and should be discussed during your consultation with Dr Mark Kohout.
Before and After: What to Expect
Immediately after surgery, you may notice swelling, bruising, and fluid accumulation. Compression garments are typically recommended to support healing. Most patients see noticeable changes within weeks, with final results developing over several months as residual swelling resolves. It’s important to follow all post-operative instructions provided by Dr Mark Kohout and his surgical team.
Long-Term Considerations
It’s important to approach liposuction as a tool to assist in body contouring—not as a weight-loss solution. The best outcomes are typically maintained when patients continue with a balanced diet and regular physical activity.
Frequently Asked Questions
Will I lose weight from liposuction?
Liposuction is not designed for weight loss. It is a contouring procedure that targets localised fat deposits.
Are the results permanent?
The fat cells removed do not return. However, remaining fat cells can still enlarge with weight gain.
Can liposuction treat obesity?
No. Liposuction is not a treatment for obesity. It is intended for patients with localised fat resistant to lifestyle changes.
Can I still gain weight after liposuction?
Yes. While the fat cells removed do not return, remaining fat cells in other areas can still enlarge if caloric intake exceeds energy expenditure.
Will liposuction improve my overall health?
Liposuction is primarily a cosmetic procedure and is not designed to improve medical conditions. Lifestyle changes remain essential for overall health and wellbeing.
What happens if I gain a lot of weight after surgery?
Significant weight gain may affect the results of liposuction and can lead to the formation of new fat cells in untreated areas.
Can liposuction help with visceral fat?
No. Liposuction targets subcutaneous fat, which lies just beneath the skin. It does not remove visceral fat located around internal organs.
Is there a limit to how much fat can be removed?
Yes. There are safe limits to the volume of fat that can be removed in a single procedure. This is determined during your preoperative consultation with Dr Mark Kohout based on your individual case.
