Q&A with Dr. Feiz:

1. How will you determine if surgery is right for someone? 
We will do a complete assessment to see if you are right for bariatric surgery. This may include an application that describes your health and weight loss history. We also will conduct other evaluations--such as nutritional, psychological, and medical--look at your BMI, and discuss any obesity-related health conditions you may have.
2. How does someone physically prepare for bariatric surgery?
Before we gain weight on the outside, your body is busy gaining weight on the inside of the abdomen. The liver is one of the organs that enlarges and gains fat as we gain excess weight (commonly referred to as a “fatty liver”). Similarly, as we lose weight, we first lose weight from the inside of the abdomen. For example, a 5-10 pound weight loss just before surgery will help shrink the liver. This can facilitate a faster surgery and may decrease postoperative pain. This can often be achieved by replacing one meal a day with a low carbohydrate protein shake.
3. What are things a patient can do on the day of surgery to prepare?
These are general guidelines. You must discuss these instructions with your physician to insure that they apply to you. Please stop all Pain Medications that can thin your blood at least 7 days before surgery. These include:Ibuprofen (Advil, Motrin), Aspirin, Naproxen (Naprosyn, Aleve), Midol, etc. Pain medications that have Tylenol or Acetaminophen are okay. Stop ALL Herbal Medications at least 10 days prior to day of surgery.
• Start a Clear Liquid Diet 48 hours prior to the day of surgery. Clear liquids include apple and cranberry juice, broth, jello, popsicles, and most sodas. If you are having Gastric Bypass surgery you will need a bowel cleansing (also referred to as a “prep”). You must drink two bottles of of Fleets Phosphosoda (over the counter, 45 milliliters each)--one at 2pm and the second bottle at 6pm. Each dose should be followed with six glasses of water or sugar-free liquids.
• Do not drink or eat anything, beginning midnight of the day before the day of surgery.
• Most medicines can be taken the day of surgery, just with small sips of water (however, your doctor will have instructions regarding specific medications).
• Bring your CPAP breathing machine, if you have one, for use in the hospital.
• Arrive early! Some hospitals and surgery centers require patients to arrive two hours early. 
What procedure would you like to do more of and why?
In the last 6 months I have been performing far more of the Sleeve Gastrectomy surgery and would choose to do more. Recovery rate is fast and results are visible right away. All my patients have been happy with this procedure and have hit their goals in 4 months time!
What is your favorite quote or saying?
God grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference.
