Depending upon a patient’s age and medical condition there may be preoperative laboratory testing required. This will need to be completed within 2-4 weeks of surgery and is typically covered by the patient’s insurance. Patients are asked to maintain their usual activity level and body weight from the time of consultation to their surgical date. Patients are required to stop smoking, vaping, and the use of nicotine patches, gum, and marijuana one month prior to surgery and a minimum of one month post-surgery. Patients are also required to stop using weight loss medications 2 weeks prior to their surgery. Surgery may be canceled if guidelines are not followed.
