What Is the Ideal Weight before your Tummy Tuck/ Abdominoplasty Surgery? – BMI impact on Abdominoplasty Surgery Results

The Tummy tuck or abdominoplasty is one of the most commonly performed plastic surgery procedures after weight loss or pregnancy. It contours the abdominal area and make the skin on your mid-section look tighter and fitter. Surgeons recommend being somewhere near your ideal Weight or BMI to be able to undergo the surgery and get the best results. Patients who are classified as obese or overweight are at higher risk and less likely to get optimal results.

The Australian Government has a NEW Medicare Item Number for a Tummy Tuck/ Abdominoplasty for some eligible post-pregnancy patients with 3cm+ Diastasis Recti (Split Tummy Muscles) if you are eligible and meet the new medical criteria. This new 30175 Medicare Item Number – is effective from 1st July 2022. Read the 30175 Medicare Item Number factsheet.

About Tummy Tuck/ Abdominoplasty Surgery

A tummy tuck/ abdominoplasty addresses concerns such as loose, saggy skin on the abdominal area in a way that strict diet and lifestyle schedules fail to. A protruding stomach, sagging skin, lax abdominal muscles can be simultaneously corrected with the help of a tummy tuck/ abdominoplasty procedure. All the effects are common in patients post-pregnancy or a massive weight loss transformation.

Tummy Tuck/ Abdominoplasty can help improve these concerns. However, you should note that Abdominoplasty isn’t a weight-loss procedure. In fact, the ideal candidates for tummy tuck/ Abdominoplasty surgery are the ones who are already at or close to their goal weight and don’t intend to lose a significant amount of additional weight post the surgery.

Understanding Body Mass Index (BMI)

BMI or Body Mass Index is a way to measure the body’s overall fat in an individual relative to their height. This measurement provides a technical classification as to whether an individual is at a healthy weight, underweight, overweight, or obese. If you are considering a tummy tuck/ Abdominoplasty, Body Mass Index evaluation will be a determining factor when it comes to your candidacy for the treatment.

Does BMI Affect My Ability to Undergo Tummy Tuck/ Abdominoplasty Surgery?

There is some discussion in the medical community whether BMI is the best measure. For some patients, body shape and where your fat is stored is also an important factor.

While a number of issues will be taken into consideration, your BMI may be one of the deciding indicators of whether you are an ideal candidate for tummy tuck/ Abdominoplasty surgery or not. Being mildly overweight doesn’t automatically exclude patients from candidacy; however, a BMI showing excess weight that could affect the overall safety of the procedure or the success of results after treatment may indicate that it is not a good idea to undergo tummy tuck/ Abdominoplasty surgery until the weight is brought down.

You may be deemed a good candidate for the procedure by Dr Hunt after he evaluates you during the consultation. Other factors besides BMI play a key role in determining your eligibility for the procedure include: age, health, expectations, and current state of your skin.

If your surgeon asks you to lose weight before surgery, then you should put in an effort to achieve a good outcome from the surgery. Here are some tips for losing weight before surgery.

Why is BMI Important in Tummy Tuck/ Abdominoplasty Surgery?

The most important reason that you should have a generally healthy BMI before a tummy tuck/ Abdominoplasty is that it can reduce risks associated with surgery and the anaesthesia used during the procedure. A person with a higher BMI and individuals who are classified as obese also may have other health conditions, such as heart disease, diabetes, and joint concerns that could increase the potential for complications during surgery. Additionally, patients who are not at a healthy weight prior to the procedure may be more at risk of aesthetic outcomes that fall below their expectations.

Safety is certainly the most common goal in determining your eligibility for the treatment. Individuals who have a healthy BMI of 30 and above are at a much higher risk of developing complications such as blood clots, abdominal fluid collection, wound separation, excessive blood loss, infection, pneumonia, and slow wound healing.

Some Ways in Which BMI Impacts the Results of the Surgery

Before you decide to go ahead with the surgery, it is important to keep in mind the following facts:

  • Your immunity is not at its best when you have a higher BMI. Having a healthy BMI will help you heal and recover faster after tummy tuck/ Abdominoplasty and greatly minimise risks
  • Your BMI is directly linked with inflammation levels and healing responses of the body. Unhealthy weight and chronic inflammation can impact your safety during and after the surgery
  • Excess fat is linked to fatty liver which is a dangerous condition and can lead to serious complications post tummy tuck/ Abdominoplasty
  • A healthy BMI will help you achieve a slimmer, trimmer and well-defined abdomen post-surgery for years to come. It can help increase the longevity of results
  • An unhealthy BMI will increase the chances of post-operative pain, inflammation and infections
  • A higher BMI will often equate to fluid retention, swelling, bruising and increase the risk of bad scarring post a tummy tuck/ Abdominoplasty surgery
  • A healthy BMI can help a smooth recovery, better results and an overall positive experience with the surgery

What Can I Do if I am too fat for a Tummy Tuck/ Abdominoplasty Surgery?

Just because your current weight or BMI is too high, doesn’t mean that you will never be a good candidate for the surgery. If your BMI is the factor preventing you from being a good candidate for the surgery, it is time to start a weight loss program that is designed to bring your BMI to a healthier range. Don’t forget, the closer you are to a healthier body weight, the better the results of the surgery will be.

Will My BMI Be the Deciding Factor?

The answer to this varies from patient to patient and can be decided after your initial consultation. As a general rule of thumb, BMI results aren’t the sole indicator of the fact that you are a good candidate for the procedure or not. Other factors that come into play include your age, expectations from the procedure, overall health, the proportions of your body, muscle mass and a variety of other things. Moreover, sometimes the BMI isn’t the most accurate way to determine the amount of fat in a person’s body and other methods are taken into account.

The best way to determine whether you are a good candidate for tummy tuck/ Abdominoplasty surgery or not is to book a consultation with a specialist plastic surgeon for a detailed evaluation.

Dr Hunt will evaluate all your unique needs during a consultation, take all factors into account and give you a clear idea about your options.
