Gastric Bypass Ssurgery >  Indications and Contraindications of Surgery

Who is a good candidate for this procedure?

Someone approximately 75 pounds overweight with a major obesity-related health problem (like type 2 diabetes, heart disease or sleep apnea) or someone greater than 100 pounds overweight without any other complications may be a good candidate for this type of surgery.

Indications and contraindications

In 1991, the National Institutes of Health (NIH) provided a consensus statement for patient selection for bariatric surgery. Patients were considered candidates for surgery if they met one of the following criteria:

Indications

  • BMI greater than 40;
  • BMI between 35 and 40 associated with significant comorbidity: hypertension, diabetes, degenerative joint disease or arthritis, sleep apnea (National Institute of Health Consensus Conference, 1991).

Absolute contraindications

  • BMI <35;
  • contraindication to general anesthesia;
  • pregnancy;
  • severe psychiatric disorders;
  • drug or alcohol addiction;
  • untreated esophagitis

To be candidates for bariatric surgery, patients should have attempted, without success, to lose an appropriate amount of weight through supervised diet changes. Patients must also comply with postoperative diet and exercise.
