When it comes to breast augmentation with breast implants, there are many questions to ask to choose the right implant. However, there is one common question that we are asked all the time: how much do breast implants weigh, and will they make me heavier?

In this blog post, you will find all the answers (and more) with advice from Breast & Body Clinic’s surgeon.

How do we measure a breast implant?

It is important to understand that we measure a breast implant in cubic centimeters (cc) of implant volume, not by cup sizes. This is because bra sizes are notorious for being inaccurate, with big differences in cup sizes between stores.

The larger the cc, the larger the breast implant, with an estimated bra cup size being anywhere between 120cc to 140cc.

Plastic surgeons measure the shell volume of breast implants by cubic centimeters or ccs.

What types of implants are available and how much do breast implants weigh?

There are two main types of breast implants to choose from: silicone implants and saline implants. You may not notice any weight variation between the two types, but there is a small difference.

How much do silicone implants weigh?

Silicone breast implants are filled with a thick, silicone gel. Sometimes there can be a slight variation in silicone breast implant weight, based on who the manufacturer is. However, in general, every 100cc of silicone gel weighs 0.23lbs. This means, a 300cc silicone implant (one of the most popular sizes) will weigh 0.69 lbs, and a pair of silicone implants is 1.38 lbs.

How much do saline implants weigh?

A saline implant is filled with sterile salt water and for every 100cc of total volume, a saline implant weighs 0.21 lbs. This means a typical 300cc breast implant filled with saline weighs 0.63 lbs, with a pair of saline implants coming in at 1.26 lbs.

As you can see there is not much weight difference between saline and silicone implants. These weights are approximate and don’t take into account the weight of the implant shell (the outer shell).

What type of breast implant and implant size you choose for your breast augmentation comes down to personal preference and the advice of a board-certified plastic surgeon. Dr Siddiqui at Breast & Body Clinic will make recommendations based on your existing body shape and size and your goals for breast augmentation.

How much do saline implants weigh - Breast & Body Clinic

Saline implants and silicone implants have only a small difference in their weights.

Can breast augmentation cause me to gain extra weight?

It is common to gain a small amount of additional weight with a breast augmentation due to the weight of the breast implants. If you notice your overall weight gain is more than what the implant weighs, this could be due to several factors:

The good news is these are all easy to fix! The fluid retention and swelling will improve with time and as you heal, and after 4-6 weeks you can get back to regular life and exercise to rid yourself of those last few pounds.

Striking the perfect balance for you.

To strike the perfect balance for you it is important to choose the right size and shape breast implant for your body composition and expectations. There is little weight difference between saline and silicone implants, so it is going to come down to personal preference and the advice of your surgeon.
