Patient Information

The decision to have weight loss surgery should be made after careful consideration and investigation of available options. To help you with this process, click on the link at the left for a list of reputable web sites that can provide helpful information. Our most successful patients are those who are well informed about what to expect before, during, and after undergoing weight loss surgery.

If you have made the decision that weight loss surgery is the right option for you, please contact us to schedule an appointment to meet with one of our surgeons. To expedite this process, you can begin the process of pre-surgical testing — even before your first appointment with us. You may bring the results of these tests to our office at the time of your first visit, or you may have them faxed to us at (212) 746-5236.

Pre-Operative Testing

Before you begin pre-operative testing, kindly click on the link at the right to download a copy of the pre-operative evaluation form. This form will be used to indicate the tests that are needed.

Pre-operative tests that can be performed before your first visit include:
  • Upper endoscopy with H. pylori biopsy
  • Colonoscopy (only needed if you are more than 50 years old)
  • Psychological Evaluation. Prior to your weight loss surgery, a psychological evaluation is needed. Please click on the link at the right to download a copy of the psychological evaluation sample letter. This form should be brought to the psychologist or psychiatrist who will perform this evaluation to ensure that they are familiar with the psychological implications of weight loss surgery. If you choose to meet with a psychiatric professional that is part of our extended care team, this document is not needed; our team members are familiar with these guidelines.
  • Laboratory Tests: T3, T4, TSH, PTH, Vitamin D 25 hydroxy
Please note that in some cases, additional testing may be necessary. This will be determined by the surgeon at your first visit.

Documents You Will Need
  • Nutrition history letter (to be provided by your primary care physician). Please click on the link at the right to download a copy of this sample letter. Your primary care physician may use this document as a guide for writing your nutritional history letter. It should be as detailed as possible due to the stringent requirements of most insurance companies.

  • Medical clearance letter from your primary care physician.

  • Preoperative nutrition assessment form (to be completed by you). Please click on the link at the right to download this form, then complete this 2-page document to the best of your ability. Try to be specific about your past attempts at more conventional weight loss. The nutritionist should receive this completed form at least 2 days prior to your appointment for nutritional evaluation. You may fax it, send it by mail, or bring it in person prior to your nutritional evaluation. You may also want to bring another person with you to your nutrition evaluation, especially if you are not the person who usually prepares meals or if you plan on someone else assisting you with meal preparation in the immediate post-operative period. (For example, if your wife or husband does the grocery shopping and cooks for you, please have her or him come with you.)

  • Dietary Guidelines Booklets. In most cases, you and your surgeon will come to an easy agreement as to the weight loss procedure that best suits your needs. After you meet with your surgeon, we will schdule a meeting with our nutritionist. During this visit, the nutritionist will provide further information regarding the type of surgery that you and your surgeon have determined is best for you. Prior to meeting with the nutritionist, please click on the links at the right to download our dietary guidelines. These documents describe meal-planning strategies that you will need to follow after your surgery and for the rest of your life to ensure proper nutrition. Please read these guidelines carefully so that you can discuss any questions or concerns with the nutritionist at the time of your visit.
