Before your surgery, you may be asked to stop smoking for 2 – 4 weeks prior to the procedure. Nicotine retards the healing process, and quitting for as long as possible before surgery helps improve blood flow.
You might also have to have a blood test before surgery is performed.
Let your surgeon know whatever medication you use since you may need to adjust these. You may be advised to stop taking certain medication, like aspirin and some anti-inflammatory drugs. You may need to stop taking some vitamins and supplements so be sure to disclose what you are taking.
Avoid recreational drugs.
Be sure to arrange for transport to and from the clinic, since you will not be able to drive yourself after the procedure.
