Care and Treatment of Bariatric and Metabolic Disorders

Is Bariatric (Weight Loss) Surgery Right for You?

Weight loss surgery is the only effective and lasting form of treatment for obese patients. But is surgery right for you?

From our experiences, being the right patient starts with the understanding that losing weight and keeping it off requires a life-long commitment. If you have that commitment, we then need to make sure that you’re a good candidate for weight loss surgery. We've established requirements you have to meet in order to be considered.  These are to make sure that surgery will a safe and effective method for your weight loss. We can't emphasize enough that surgery is a serious medical procedure and the start of some pretty big lifestyle changes.

Bariatric surgery requirements

  • Attend a seminar to learn about weight loss, bariatric surgery, and your health.
  • Six months of supervised (physician or Weight-Watchers) attempts at weight loss with documented weights (insurance requirement), dependent on your specific insurance plan
  • Nutritional evaluation and completion of food diary 

Meeting with a nutritionist before and after surgery is critical. You will have no more important change in your life than the change in your eating habits after surgery. It’s critical to educate yourself regarding how to best meet this challenge.

  • Psychological evaluation
  • Primary care physician referral
  • Patients are current on preventative health tests, including mammograms and colonoscopies.

Diagnostic tests

To fully optimize patients pre-operatively, we require the following diagnostic tests. These should be completed within six months prior to surgery. These diagnostic tests will allow us to provide you with the best care possible, and are always meant to assist care, not deny it. You can work with your primary care physician to complete many of these tests.

  • CXR
  • EKG
  • Blood Work
    • CBC
    • Complete metabolic panel, including calcium and liver function tests
    • Thyroid function tests
    • Lipid panel
    • Fe Panel
    • B1, B12
    • Folate, Thiamine
    • Homocysteine, C-Reactive Protein, Lipoprotein a – to assess cardiac risk factors
    • HgbA1C (if known diabetic)
  • Cardiac Echo – hx of phen-fen or long-standing sleep apnea or cardiac risk screen
  • Stress Test per physician discretion
  • Greenfield Filter – Your surgeon will make this decision and is usually indicated if history of blood clots in your lungs or legs, severe sleep apnea, weight >400 lbs. The filter helps prevent blood clots from traveling from your legs to your lungs where they can be fatal. Stanford  physicians are able to place temporary filters that are removed 2-4 weeks after surgery.
  • Cessation of smoking, steroid use and immune suppressant medication. Use of any of these drugs will jeopardize your recovery.
  • Endoscopy and/or Upper GI
