We recommend that patients refrain from taking any "supplements" or other dieting during the post op period for at least 3 months. This is important to allow your body to heal. It needs the building blocks that only a well balanced healthy diet can provide! As far as "diet pills" are concerned, we would recommend that you have a thorough discussion with your family doctor who is managing the prescriptions you are taking. Also, discuss this with the operating surgeon performing your procedure prior to beginning any course of appetite or mood altering medications.Remember, the success of the surgery always depends on following the advice of your doctor to assure good wound healing.
