How Much Do Breast Implants Weigh?


Choosing to undergo breast augmentation is a crucial medical decision with numerous implications. At Radiance Plastic Surgery, we are committed to improving client understanding and decision-making by sharing information backed by scientific evidence.

Debunking the Myth of Weight Gain After Breast Augmentation

Many individuals often expect to gain a significant amount of weight after undergoing breast augmentation. However, any increase in weight noticed after the surgery is usually temporary. The apparent weight gain can be attributed to factors such as fluid retention due to anesthesia, medication intake, and the surgical procedure itself. This trend is not exclusive to breast procedures but is also seen in other types of surgeries like liposuction and body contouring. Therefore, it is recommended to refrain from weighing oneself for about ten days after surgery to prevent false impressions.

Analyzing Breast Implant Weights:

Silicone Implants: For every 100cc, silicone breast implants weigh approximately 0.23lbs. Hence, a 300cc silicone implant would weigh around 0.69 pounds. Subsequently, a pair would amount to 1.38 pounds, under 1.5 pounds. The conversion factor for silicone stands at 1cc divided by 426.67.

Saline Implants: In comparison, saline breast implants for every 100cc weigh about 0.21lbs. A 300cc saline implant, therefore, weighs 0.63lb. Cumulatively, a pair of such implants weigh approximately 1.26 pounds. The conversion for saline is 1cc divided by 473.18.

Depending on the specific manufacturer involved, some minor variations or nuances could exist.

Choosing Saline Over Silicone: A Matter of Weight?

The weight difference between saline and silicone implants should not be a deciding factor. Texture, aesthetics, and patient preferences are more important considerations.

In Summary

Breast implants do contribute to a minor post-surgical weight increase. However, it is essential to differentiate between transient fluid retention weight and the actual weight of the implant. At Radiance Plastic Surgery, our ethos centers on transparency, excellence, and an unwavering commitment to client care.

Our team is committed to answering questions and clearing up any confusion regarding breast implants, including details such as implant weight, which can be a crucial factor in the decision-making process for those considering breast augmentation.


What is the typical weight of a breast implant in Canada?

The standard weight for a 300cc silicone implant lies at approximately 0.69 pounds. When considering two such implants, the combined weight rests below 1.5 pounds.

Is a significant weight gain expected post-breast implant surgery in Canada?

A slight weight gain following surgery is usually due to temporary factors like fluid retention from anesthesia rather than the implant’s weight.

Are saline implants recommended since they are marginally lighter than silicone implants?

While saline implants are lighter than silicone implants, the difference in weight is negligible. Therefore, the choice should be based on comfort, personal preference, and aesthetic goals.
