Patient Information

When you choose to have weight loss surgery, we will provide you with a wealth of patient information about the treatment you will undergo at the Dallas Surgery Center or Carrollton's Baylor Medical Center, and your responsibilities before and after surgery. You will receive guidance about insurance, and, if necessary, financing for your procedure. We feel that when patients have all the information they need and understand the reasons for our instructions, they have the best chance for success in maintaining weight loss. If at any point you have questions that remain unanswered, please contact North Texas Bariatric. Dr. Veninga or a knowledgeable staff member will make sure that you get the information that you need.

Pre-Op Instructions – In Preparation for Surgery

Call Day Surgery one week prior to surgery date to schedule pre-op appointment (972-394-2470). The appointment is for lab work, chest X-ray, EKG, and any other tests Dr. Veninga may order. The hospital will need all your insurance information and they will let you know where to report the morning of surgery. You will need to arrive one to two hours prior to your surgery time.

Dr. Veninga has all patients begin the OPTIFAST® diet two weeks prior to surgery. You take five servings a day. This is a fortified meal replacement which will result in considerable weight loss, much of it water weight. This results in a smaller liver and less upper abdominal fat, which should make the operation technically easier to perform.

Do not eat or drink anything past midnight the night before your surgery. On both the night before surgery and the morning of surgery, scrub your abdomen with Hibiclens. Hibiclens can be purchased at most drug or grocery stores. If you have any questions regarding these instructions, please feel free to call the office: 972-939-8218.

Rules for Post-Op Success

To help ensure the long-term success of your weight loss surgery, you should closely follow our post-op rules:

  • Eat three small meals per day.
  • Eat only nutritional solid food.
  • Eat slowly, and when you feel full, stop eating. If you feel full after consuming less food than is prescribed, don't try to eat more. If your prescribed meals do not give you a sense of satiety, or if you feel hungry within an hour after eating, contact North Texas Bariatric to schedule an evaluation.
  • You must not eat between meals.
  • Do not drink liquids with your meals.
  • All liquids you consume must be low calorie or, preferably, have zero calories.
  • Do not eat sugary foods or other foods with a high caloric content. Gastric banding cannot control the introduction of high-calorie foods if they are in liquid or slurry form.
  • Stay away from foods that cause gastric distress. Reduce your coffee consumption. Do not drink alcohol or carbonated drinks for the first three to six months.

After your surgery, you will receive printed instructions for the dietary protocol you must follow. We will also provide instructions on the appropriate dietary supplements for you following surgery. Six Weeks Post-Op

Protein Supplements

Protein supplements will be an essential part of your diet following surgery. We at North Texas Bariatric highly recommend OPTIFAST®, Beneprotein®, and Achieve One™ protein supplements. These products taste great and provide you with an excellent source for your daily protein requirements. We have OPTIFAST® and Beneprotein® products for sale in our office.
