Breast Augmentation and Recovery. Everyone says stay off fat burners for 3 weeks before and after breast augmentation. Why?

There are many products that can contribute to bleeding and bruising.  It is always best to discuss any OTC medications or supplements you may be taking before scheduling your surgery date to make sure certain products are out of your system before, during and after surgery. 

are not contraindications to surgery and there is not strict rule about its use around procedures.  If you're using diet pills such as Phentermine, those drugs affect the anesthetics used and should be stopped 3 weeks prior and may be resumed post-op when cleared with your surgeon.  As for OTC medications, your surgeon should be able to tell you what you can and cannot use but as you're already seeing here, every surgeon has their own guidelines.  In my practice, stopping a week prior and starting up a week post-op is good enough.
