Activity following a breast augmentation varies from individual to individual. Certainly everybody should be cautious within the first couple of weeks. I would limit activity that uses your arms and chest muscles during this time. However beyond this I like to gauge activity depending on the position of the implants. If the implants are placed beneath the muscle it is very common for those implants to stay high for several weeks until they drop into their appropriate pocket. If you start activities that cause contraction of the chest muscles while the implants are not in this pocket then the implants can remain high for a longer period time. Occasionally surgery is necessary to release the capsule that forms if they stay high for several months. I would say that most implants have dropped into the appropriate pocket by three months. Keep in mind I have had some patients that have remained in the appropriate pocket from the first postoperative day. Everybody’s different.
