Bariatric Surgery Frequently Asked Questions
How to Prepare for Your First Appointment
If you are thinking about having surgery, a member of our bariatric surgery team will talk with you over the phone to determine if you might be a candidate. Some of the questions they will ask you may include the following:
- What is your age? (Surgery is only available for adults 18 and older)
- What is your height and weight? (This will be used to calculate your BMI.)
- Do you have any of the following health conditions:
- Congestive heart failure
- Diabetes
- Gastroesophageal reflux disease
- High blood pressure
- Polycystic ovary syndrome
- Pseudotumor cerebri
- Osteoarthritis
- Sleep apnea
- Urine stress incontinence

[MUSIC PLAYING] Have you ever used a body mass index calculator to get your BMI number? It's easy. Just search the internet for a BMI calculator and plug in your height and weight. Confused about what your number means? Wondering if you really need to be worried about your weight at all? I mean, sure, you've gained a few pounds over the years, but it's not that big a deal, right?
Well, answer these questions. Are you 100 pounds heavier than you should be? When you calculate your BMI, is it over 35? Over 40? Do you also have diabetes, sleep apnea, high blood pressure, or high cholesterol? If you answered yes to two of these questions, you qualify for bariatric surgery.
That's right. You have severe obesity. And ignoring it or taking more pills for your medical problems isn't wise. In fact, your life expectancy is at least seven years shorter than someone who didn't answer yes. If your BMI is really high like 55, you are likely to die 14 years earlier than you would at a normal weight.
It's time to get a sense of urgency about this problem. And it's time to face facts. Obesity is a chronic disease. And it needs to be treated. It's easy to blow it off now because it doesn't hurt or cause a lot of symptoms. But just like cancer and heart disease, it will progress without treatment. And it will end your life early.
If you have obesity, it's not just a willpower problem. You've tried a hundred times to lose weight with diets and exercise, so willpower isn't the issue. It's biology, environment, genetics. And yes, it's behavior too. If you're obese, you just have to own it. It doesn't mean you need to be embarrassed or ashamed. Would you be embarrassed if you were told you had diabetes? No, you would get it treated. Same should be true for obesity.
Unfortunately, many doctors don't have the time or expertise to discuss or treat obesity. There are experts out there, though, that focus their careers on treating this disease. Bariatric surgery programs offer all kinds of treatments for obesity, including medication, endoscopic treatment, and surgery. Learn more about these safe and effective treatment options.

Frequently Asked Questions about Bariatric Surgery
UChicago Medicine follows guidelines supported by the National Institutes of Health in order to determine a patient's eligibility for weight loss surgery. Rather than using weight, we use body mass index (BMI) as a criteria for surgery — excess fat in relation to height. Individuals are candidates for surgery if:
- Their BMI is greater than 40 or between 35 and 40 with major obesity-related medical problems, such as diabetes, hypertension, hyperchloremic, sleep apnea. Check your BMI.
- They have failed previous attempts at weight loss in a medically supervised program
Before becoming eligible for surgery, you will meet with our surgeons, dietitians, psychologists and members of our nursing staff for a full evaluation.
No, surgery is not a solution for everyone. We only determine whether a patient is right for surgery after a complete evaluation and discussion with the patient. Because weight loss surgery is a life-altering procedure, we want to make sure our patients are committed to making the lifestyle changes needed for a successful procedure and life-long health maintenance.
All major surgery comes with risks, and the risks are different for each patient. At UChicago Medicine, our surgeons have better outcomes than most. During your first appointment, your surgeon will explain your individual risk level.
The amount of weight you lose and how fast you lose it depends on which weight loss surgery you have. Patients who have adjustable gastric banding (Lap-Band) procedures usually lose weight more slowly the first year than those who have gastric bypass (RYGB) or duodenal switch procedures (DS).
In our program, the average patient loses between 68 to 78 percent of his or her excess body weight after RYGB or DS and between 60 to 70 percent after vertical sleeve gastrectomy (VSG). Weight loss with gastric banding is less predictable. The amount of weight loss also depends on your age, gender, starting body mass index and your ability to adhere to lifestyle changes necessary to make surgery a success.
Weight loss surgery has actually been linked with producing a sudden positive change in fertility. Women with fertility problems linked to obesity may begin ovulating regularly for the first time in years post-bariatric surgery. However, women should avoid pregnancy for at least 18 months after surgery. Please discuss any pregnancy plans with your surgeon during one of your clinic appointments.
Insurance coverage depends on your plan. For example, some insurance companies require a patient to be in a physician-supervised weight loss program for at least a year before surgery. Before you come in for your first appointment, please call your insurance company to find out if weight loss surgery is covered. UChicago Medicine has an insurance coordinator who can help you after you are approved for surgery.
If you are interested in weight loss surgery, please call us at 1-773-702-1618. We will discuss our program and your weight loss surgery options.
When you come to your first appointment, please bring the following information:
- Social security number
- Insurance card
- Any paperwork needed by your insurance carrier (managed care referral authorization, for example)
- Any past medical records
- A list of your current medications
- A hand-written food diary
- The name of your primary care doctor
You can see our physicians at the UChicago Medicine Duchossois Center for Advanced Medicine on our main medical campus in Hyde Park as well as at our Orland Park and River East locations.
Plan to be at your first appointment for about two hours. It should take place after you have attended an information session. The surgeon or nurse practitioner will perform an extensive history and physical. Our dietitian and psychologist will also see you at this appointment.
This depends on your insurance provider and the criteria they require, as well as the tests and requirements our team finds necessary.
Your hospital stay will depend on the type of weight loss surgery you have. Generally, hospital stays are between one and three days.
Again, your time off of work will depend on the type of weight loss surgery you have and the type of work you do. In general, plan to take about two to four weeks off of work. While you will not be incapacitated by any means, you will use this period to focus on healthy eating and drinking habits.
Yes. Because your medical condition will change following weight loss surgery, it is essential that you are closely monitored by your primary care doctor. We will keep him or her informed on your progress.
As you start losing weight, you may notice excess skin. The amount of excess skin you experience is due to your weight loss, age and smoking habits. Some patients choose to have surgery to have this skin removed. Learn about body contouring after weight loss procedures performed by UChicago Medicine plastic and reconstructive surgeons.
Yes, but the number depends on your weight loss procedure. All procedures require a lifetime of vitamin supplementation. More supplementation and stricter adherence is required with Roux-en-Y and Biliopancreatic Diversion. Our dietitians will help individualize your vitamin regimen.
Regular exercise is extremely important for maintaining your weight loss. Your bariatric surgery team will help you with the types of exercise you should be doing and how soon after surgery you should start doing them.
Yes. For most people who have experienced major weight loss after weight loss surgery, excess skin can be painful and cumbersome. UChicago Medicine’s board-certified plastic and reconstructive surgeons are highly experienced in body contouring procedures.
