How your Weight and BMI impacts your Tummy Tuck Surgery results

How your BMI impacts your Tummy Tuck surgery results

Have you ever wondered if your BMI or weight will impact your Tummy Surgery results? Are you exploring Abdominoplasty and liposuction after having children or losing weight? You may wonder if you’re FIT and LEAN enough to get a good result. If so, you’re not alone. Most Tummy Tuck Surgery patients (but not all) are carrying a bit of excess weight. This blog will help explain how your BMI can impact your surgery result.

Are you carrying too much weight to get a good outcome from a Tummy Tuck or Liposuction?

Are you at a good weight for body contouring abdominoplasty surgery? Or do you need to reach a lower, stable weight before your surgery performed?

  • It really depends on the individual patient.
  • A consultation is the best way to gain a clearer indication of your suitability for any body contouring procedure.

That noted the a good surgery candidate will have  a BMI of 30 or below. Some surgeons will operate on patients as high as BMI 35-39 but most will NOT operate on a patient of BMI 40 or above.

If you are overweight or in the obesity BMI range of 30 or above, you’re less likely to be a suitable candidate for surgery.

Another consideration for surgery is whether your weight is stable or wildly fluctuating throughout a year.


But an IDEAL BMI – a healthier lower BMI more in the 25-29 range, may get you an even better surgery result.

If you’re wondering how your current body weight and BMI might impact your surgery results, whether a Tummy tuck, liposuction or other procedure, read this important blog on how weight changes and body fat ratios can impact your results.

7 ways weight and body mass index can impact tummy tuck or liposuction surgery results.

Before you do further research into your Abdominoplasty/Tummy Tuck options, it’s important to keep the following in mind.

1: Good recovery processes after Plastic Surgery require good health.

  • Your immune system impacts your surgery experience, wound healing/scar formation and other recovery experiences.
  • Your body’s immune system is REDUCED when you are carrying too much weight or eating unhealthily.
  • Reduced immunity leaves you more susceptible to experiencing unwanted surgical complications and other risks.

“So the better your overall health, including your BMI, the better your entire surgery experience is likely to be.”

2: Your body fat index or BMI is also a factor in inflammation levels and healing responses.

  • Unhealthy body weight and/or chronic inflammation CAN impact patient-safety both during and after your operation.
  • It can impact post-operative pain, inflammation and infection risks.
  • Higher inflammation levels also usually mean you’ll tend to have more swelling, bruising, fluid retention, pain and discomfort than if you were at a lower BMI.

3: Excess Fat Also Means A Fatty Liver.

  • Being overweight or obese – with a high BMI – is associated with having what’s called a fatty liver.
  • This means your healthy liver tissue cells have become “replaced” or interspersed with fat cells. This greatly impedes the function of your liver and puts you at higher health and higher surgery risks.

4: Why is reaching a stable, healthy weight so important before you have surgery?

  • Your weight – and your daily nutritional intake – impact your surgery experience, healing processes and overall satisfaction with results over time.
  • When you schedule cosmetic or plastic surgery, it’s important to go into the surgery with the healthiest BMI you can achieve.

For you to achieve the best results from your surgery it’s crucial that you sustain a healthy weight and lifestyle over time.

  • A healthy lifestyle and healthy BMI helps you DURING your operation AND in the months and years that follow your surgery.
  • If you’re at a healthy weight/ideal BMI, you’ll likely end up getting a more visually pleasing result.
  • You’ll also be more likely to sustain a firmer, trimmer abdomen and well-defined waistline for longer (years versus months).

Plus – you’ll be more likely to have realistic expectations.

  • It’s important to recognise that Abdominoplasty Surgery results depend as much on YOUR choices as on the Surgical techniques and initial results.
  • So having an ideal weight/healthier BMI typically means you’ll REDUCE your obesity-related risks during surgery, including of developing sepsis  (a potentially fatal illness for which overweight/obese patients have higher risks) compared to healthy-weight patients having a surgical procedure.

5: How is BODY WEIGHT/BMI linked with realistic expectations about surgery, results and what it can – and can’t – accomplish?

What you do DOES MATTER in terms of your results and long-term satisfaction with your surgical investment.

‘When you recognise that you’re responsible for the longevity of your surgery results – you’ll be likely to understand not only the BENEFITS of having surgery – but what surgery CANNOT accomplish.”

You’ll recognise that Abdominoplasty surgery is a serious option, not the go-to method for a quick fix for your weight gain concerns.

  • Surgery is NOT a fix for weight problems, as you’ll discuss during your consultation with Dr Wyten.
  • Instead, surgery is an option for reducing excess skin folds and some excess fat that cannot be exercised away.
  • Surgery can also repair damaged abdominal muscles after pregnancy or weight loss (diastasis recti) to restore core strength and reduce back pain.

Surgery has certain risks that you need to consider carefully before proceeding with a body shaping procedure. One of those risks is being dissatisfied with results because you weren’t sustaining a stable, healthy BMI.

6: What happens if I gain weight or get pregnant after a Tummy Tuck or liposuction?

  • If you gain weight again or lose-and-gain weight repeatedly after your surgery, you’ll greatly impede your results – your shape is going to change.
  • Future pregnancy will also change your Abdominoplasty or liposuction surgery results and your satisfaction with longer-term outcomes.

Ageing changes your results over time even if you stay at the same weight, but weight fluctuations usually reduce patient satisfaction with results.

  • Weight changes or weight gain AFTER an operation may leave you feeling less satisfied with your body shape and/or waistline shaping results.
  • Alternatively, if you keep fit and stable in your weight, you’re more likely to be happier with your Tummy Tuck results for a longer period of time.

These are great reasons to find ways to reach a stable and sustainable healthy Body Mass Index (BMI) before your surgery. A stable weight is one you’ve reached and sustained by making lifestyle changes for a minimum of six months, but ideally for several years.

7: What does it mean to have a healthy BMI or ideal body weight?

  • The word “healthy” means that your BMI is near – OR IN – a healthy or normal range VS being in the overweight or obese BMI range.
  • A healthy BMI is NOT in the overweight or obesity category, although some overweight individuals may be healthier than others.
    • Even though some obese patients are somewhat fit, a high BMI indicates compromised health and immunity functions and potentially a fatty liver.
    • Obesity increases surgery risks including but not limited to; circulation concerns (DVT) and wound breakdowns.
  • Whilst SOME obese individuals are relatively healthy, if you fall into the OVER 30 BMI range, you’re really not a good candidate for surgery and over a BMI of 40 most surgeons will not operate.
  • Most overweight individuals will incur higher surgery risks or may find they are not suitable candidates, as they won’t get a good result.

Ideal body weight is typically within a healthy BMI range, although everyone’s ideal goal weight will be unique to their genetics and body shape. Aim for a healthy, sustainable weight before you have surgery.

So what does your BMI status actually mean?

  • Interpretations vary somewhat as to the impact your BMI has, other than obesity.
  • Different medical professionals may have different views of the data. Plus individual patients can vary in health outcomes and risks even though they have a similar BMI status.
  • According to the World Health Organisation, your BMI indicates whether you are at a so-called ‘normal weight range’ for your height, or whether you are in the underweight, overweight or obesity ranges.


Obesity and Plastic Surgery risks.

Having an elevated BMI does not guarantee you’re NOT healthy. It DOES, however, increase your surgery risks. It is also LIKELY to suppress your immunity responses and impede your recovery processes.

  • Here’s a graph indicating that even overweight individuals may be healthy, and even underweight individuals may be unhealthy – but it is far less likely.
  • Aim for normal weight or a BMI under 30 before you consider having a surgical procedure to reshape your body after pregnancy or weight loss.

Do I need to lose weight before having surgery such as a Tummy Tuck or Liposuction?

  • Typically the answer is YES, most of us DO need to get our weight in check before we have body contouring surgery.
  • That’s because losing weight BEFORE plastic surgery – and reaching a healthier, sustainable “happy” weight – goes a long way to getting a good abdominoplasty or liposuction result.
