Bariatric Surgery

Bariatric surgery in Topeka, KS

When diet, exercise, and medication aren’t working, weight loss surgery can help you achieve your weight loss goals and live a healthier life. At the University of Kansas Health System, we understand that bariatric surgery is a big decision. Our doctors are here to help answer any questions you may have about weight loss surgery, including whether it may be right for you. We offer pre-surgery counseling, post-surgery support, and a wide range of resources to help you live a healthier, more active life.



Weight loss procedures we offer

Research has shown that weight loss surgery is an effective way to achieve long-term weight loss. It can also improve conditions like diabetes, heart disease, and sleep apnea. Our medical weight loss program provides bariatric surgical treatments to treat a wide range of conditions that affect your ability to maintain a healthy weight.

We offer the following types of weight loss surgery:

  • Biliopancreatic diversion with duodenal switch (BPD/DS)
  • Revisional surgeries
  • Roux-en-Y (gastric bypass)
  • Sleeve gastrectomy

Bariatric surgery may be an option for adults with a BMI of 40 or more, or for patients with serious health conditions like diabetes or heart disease who have a BMI between 35 and 40. Patients with a BMI below 35 do not qualify for bariatric surgery.

If you have additional questions, please contact our bariatric patient navigator by calling (785) 270-7326.

After weight loss surgery

Weight loss surgery is just the first step towards a healthier life. To help you achieve the best results possible, our weight loss program also provides:

  • Exercise education and wellness classes
  • Nutrition education and guidance
  • Regular follow-up appointments
  • Support groups

Research has shown that patients who attend support groups are more successful in reaching their weight loss goals after surgery. For this reason, we offer free online weight loss support groups to our patients who have had weight loss surgery or are about to have weight loss surgery. The virtual group provides education and encouragement through guided discussions and guest speakers— all from the comfort of your home. Family and support persons are welcome to attend as well.

To learn more about our virtual support groups, please click here.

Schedule an appointment

The decision to have bariatric surgery is best made with lots of information and an equal amount of support, and that’s just what we provide. First, you’ll meet one of our surgeons at a free seminar, where you’ll learn about our process and the surgical options we provide. Then you’ll have a one-on-one appointment to discuss which option is right for you.

There are three steps required for an initial consultation at our weight loss clinic:

  • Click here to watch our online seminar
  • Complete the short quiz following the seminar and earn a score of 100.
  • After you complete the quiz, a member of our support staff will be in contact with you to review insurance coverage and schedule your first consultation.

We plan your personalized treatment together, from surgery through the lifestyle changes that will occur as a result. You’ll have access to post-surgery resources such as support groups, weight loss seminars, nutritional advice, exercise classes — and, of course, our caring team of physicians. With help from one of our specialists, you’ll be on your way to the healthier life you deserve.

    The Worst WLS Mistake You Can Make

    The Worst WLS Mistake You Can Make

    By Katie Jay, MSW: Certified Wellness Coach

    Have you heard the Aesop’s fable about the dog and his shadow? In the story, a hungry dog manages to get a morsel of meat. Thrilled with his acquisition, the dog decides to take it back to his den where he can devour it in peace.

    As he hurries home, the dog dashes across a plank lying over a brook, but as he’s moving across, he sees his shadow reflected in the water.

    Weight loss surgery significantly reduces mortality and results in remarkable weight loss and reversal in several obesity-related comorbidities.  There is a lot of evidence that the resolution of inflammation that occurs after bariatric surgery mitigates some of these comorbidities.

    Tidbit Tuesday: Spring Has Sprung
