Can a cold cause a breast augmentation to be postponed?

I am sorry to hear about your concerns prior to your day of surgery. Generally speaking, patients undergoing elective surgery should be at their optimal (or close to) level of health prior to proceeding. It is especially important that there be no compromise of pulmonary function or active source of infection present.
Your plastic surgeon will be the only relevant resource when it comes to determining what medications you can take prior to surgery and your ability to proceed at this time.
Best wishes.

Your surgeon should be notified if you develop a cold before surgery. Depending on the severity of your cold, your surgery may be rescheduled.

Thank you for your question.  A significant cold or upper respiratory infection creates a serious risk of complications or pneumonia following general anesthesia.  Please consult your surgeon.
