Am I A Suitable Weight For Plastic Surgery?

Sep 6, 2023 | Blog, General

When it comes to Plastic Surgery procedures in Australia, maintaining a healthy Body Mass Index (BMI) is essential for your safety. If your BMI falls within a healthy range, you’ll minimise your own exposure to risk of complications during and after your surgery and increase the likliehood of optimal results. In this blog, we’ll explore the importance of BMI where Plastic Surgery is concerned and why we use it as part of your assessment for Plastic Surgery. 

Are there weight restrictions for Plastic Surgery in Australia?


While there isn’t a specific ‘weight’ restriction, Plastic Surgeons in Australia insist that any client undergoing Plastic Surgery be within a healthy Body Mass Index (BMI) prior to their surgery.

Achieving a healthy BMI before surgery typically leads to better surgical outcomes, a smoother recovery and faster healing. For these reasons, your Plastic Surgeon will not accept clients with a BMI considered too high or too low.

Importantly, weight gain in the future can also negatively impact on results, so we encourage clients to achieve and maintain their ideal weight or healthy BMI for at least 6-months before their surgery.


What is Body Mass Index?

Body Mass Index (BMI) is a measure used to assesses the amount of body fat relative to your height and weight. You can calculate your BMI using the Heart Foundation BMI Calculator. You can also calculate your BMI using this formula

BMI = weight (kg) / height (m)2

Unlike weight as a measure, BMI considers your height – so if you’re taller, you’re naturally expected to weigh more than someone who is shorter. 

Importantly, a BMI is not a perfect indicator, and does not measure how healthy you are. It also doesn’t take into account important factors like age, gender and body composition (fat, muscle and bone). Because of these limitations, BMI is not an effective measure for those with a higher muscle mass such as athletes, or those with lower muscle mass such as children or the elderly. 

What Does My BMI need to be for Plastic Surgery?

The ideal BMI for surgery is likely to vary according to the nature of your surgery. Some of our Plastic Surgeons will not accept clients with a BMI below 17 or over 30. Conversely, for clients undergoing Weight Loss Surgery, the client’s BMI must be greater than 35.

Why Is BMI Important for Plastic Surgery?
