  1. Why should I have my weight loss surgery at the University of Michigan?

    The University of Michigan offers a specialized, multi-disciplinary Bariatric Surgery team who works with you on an individual basis to provide you with the knowledge and skills needed to be successful after your weight loss surgery. We provide pre- and post-operative nutritional education and counseling, support group meetings, and an on-line patient community to help you deal with the nutritional, lifestyle, and emotional changes you will experience. Our staff includes surgeons, physician assistants, nurses, dietitians, and psychologists, all of whom specialize in bariatrics and are available for life long care and support.
  2. How much weight will I lose after bariatric surgery?

    Weight loss is variable from patient to patient but on average you can expect to lose 65-70% of excess body weight following Roux-en-Y Gastric Bypass surgery, 55-60% following Sleeve Gastrectomy and 35-45% of excess body weight following Laparoscopic Gastric Banding (LAP-BAND).
  3. What is the recovery time following surgery?

    For both procedures you are generally up and walking on the first day. The day after surgery you are able to begin a liquid diet. For most individuals pain is well controlled with liquid oral pain medication after the first day. Your hospital stay averages 2 to 3 days. You generally return to work in 2 to 4 weeks.
  4. Does my insurance cover weight loss surgery?

    Most insurance companies have determined weight loss surgery to be a covered benefit for obesity and obesity related co-morbidities. We encourage you to contact your insurance provider to determine if weight loss surgery is a covered benefit under your policy and to see if they have any additional criteria. Insurance providers are changing their individual criteria for weight loss surgery at least every enrollment period. Please check with your provider frequently to see if their criteria have changed. See the patient insurance information form, located in the Medical/Nutritional Questionnaire. It is important to complete page 2 of this form before your new patient evaluations.
  5. How long from the time I attend an informational session before I am scheduled for surgery?

    The length of time from the informational session to the date of your surgery varies. If your insurance carrier has no additional criteria, the average time from the informational session to the date of surgery is 3 to 6 months.
  6. How often am I required to see the surgeon/physician assistant and dietitian after surgery for follow-up?

    Following the gastric bypass or sleeve gastrectomy procedure, you will see the surgeon and dietitian at 2 weeks and 2 months. You will then see endocrinologist and the dietitian at 6 months, 12 months and annually. You can schedule additional appointments with our dietitian, as you feel you need.

  7. When will I schedule my surgery date?

    The actual surgery date is not discussed until after all the requirements from the review committee have been completed.
