Calculate your BMI

BMI Calculator

Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

Comprehensive support throughout your weight loss journey

If you think you may be a candidate for bariatric surgery, please attend one of the free weight loss surgery seminars at North Suburban. The sessions occur on the second Thursday of each month from 6 p.m. to 8 p.m. in the Aspen Room. (Enter through the main entrance and take the elevator to the basement floor.)

To RSVP for the next weight loss seminar, please call (303) 920-4362.

Talk to your insurance provider

Now that you have attended our free introductory seminar, call the number on the back of your insurance card. Provide your ID number, and ask if bariatric surgery is a covered benefit. (Make sure you provide your ID number so they can check your employer policy if that applies to you.)

Then, ask these questions:

  • Does my insurance require a referral from my primary care doctor before I see the bariatric surgeon? (If so, you will have to have this appointment before setting up your consultation.)
  • Does my insurance cover any of these weight loss surgeries? (You can provide these codes: Gastric bypass: 43644; Gastric banding: 43770; Sleeve gastrectomy: 43775)
  • Does my insurance require a medically managed weight loss period? If so, how long is it?
  • What are the out-of-pocket costs?

Consultation with a bariatric surgeon

At the seminar, you will have an opportunity to sign-up for a one-on-one consultation with our bariatric surgeon. In addition to answering any questions you have, the doctor will speak with you about:

  • Specific health issues and how they apply to the procedure you choose
  • Different surgery options and how each fits your goals
  • Risks and complications of each procedure
  • The criteria for becoming a bariatric patient
  • The support structure we provide and the next steps along your journey

Consultation with a registered dietician

Following the consultation with the bariatric surgeon, you will meet with our registered dietitian (RD). In this meeting, the RD will complete a nutrition assessment, review the nutrition implications of surgery, discuss behavior changes required for weight loss success, as well as diet progression and supplementation use.

The RD will create an individualized nutrition care plan that will address any concerns you have, as well as assist you in meeting the lifelong nutrition guidelines after weight loss surgery.

Medically managed weight loss period

Most health insurance providers require that you complete several months of a medically supervised diet before approving your weight loss surgery. Our goal is to help you during that process and answer any questions you have.

Each month, you can expect us to discuss:

  • How are your health changes going?
  • Are you completing the necessary steps for surgery?
  • If you are a smoker, have you quit?
  • How often does your insurer require you to check in with your doctor during this weight loss period? Are you keeping up with your appointments?

We encourage you to always call us with questions. However, we want to make sure that you feel supported during this period, which is why we want to meet with you monthly.

Completion of specialist appointments

The next step is to schedule appointments with specialists to ensure you have surgery clearance.

In your consultation with the bariatric surgeon, we will discuss which specialists you will need to see, based on your health status. A psychiatric evaluation is mandatory, as is the dietician pre-operative class.

After all steps have been completed and you have been cleared for surgery, we can schedule your procedure at our bariatric clinic.
