A multifaceted issue
Obesity is a complicated, progressive disease caused by a wide variety of factors. The disease is associated with numerous health conditions, including diabetes, sleep apnea, heart disease, liver disease and joint problems, and is life-threatening. The Medical and Surgical Weight Management Program at UW Health is here to help with surgical and nonsurgical options.
We give you all the tools you need to lose weight safely and effectively. We design a treatment plan just for you and help you reach your weight loss goals and improve your health.
We’ll find the right treatment to help you succeed
When you’re thinking about surgery, we ask you to watch a few short videos. We also ask you to provide some details about yourself and meet with members of our team.
You’ll have seven months of group and one-on-one meetings with a health psychologist before your surgery. We work with you on nutrition and exercise to help prepare your body for surgery and beyond.
The gastric bypass or Roux-en-Y surgery is the most common surgery in the U.S. This procedure may be done either through an open approach (large incision) or via the more common laparoscopic approach.
The Roux-en-Y gastric bypass surgery procedure
During the operation, surgical staples are used to create a small pouch at the top of the stomach. A segment of the small intestine is then attached to this pouch. Food bypasses most of the stomach and the first part of the small intestine.
Most patients typically have a one- to three-night hospital stay.
Benefits of Roux-en-Y Gastric Bypass
The Roux-en-Y gastric bypass operation helps you lose weight by:
Caloric restriction: The small pouch created can hold only two to four tablespoons at a time, thereby drastically reducing the amount of food that can be eaten.
Nutrient malabsorption: Food bypasses a large portion of the stomach and the first portion of the intestine.
Additional benefits of Roux-en-Y gastric bypass include:
Significant hormonal changes for hunger and glycemic control
Immediate and robust weight loss (six to seven pounds per week in the first six to 12 months)
It is the most durable procedure for long-term weight loss
The sleeve gastrectomy procedure may be done through an open approach (large incision) or via the more common laparoscopic approach.
A large portion of the stomach is removed, leaving a narrow tube-shaped pouch with a capacity of approximately three to four ounces.
Unlike the Roux-en-Y (gastric bypass) there is no bypassing of the intestines.
Most patients typically have a one- to two-night hospital stay.
Benefits of sleeve gastrectomy
The sleeve is primarily a restrictive procedure, meaning patients lose weight by limiting the amount of food that can be eaten at a time, with some change in the ability to absorb calories and nutrients.
The sleeve may lead to hormonal changes that decrease hunger, and have metabolic effects that may speed the resolution of diabetes.
The sleeve gastrectomy procedure provides moderate weight loss (four to five pounds per week in the first six to 12 months).

Frequently asked questions
Deciding to have surgery is a significant decision. The following information is intended to help answer common questions about the procedure.
Please note that coverage varies widely, each employer may purchase a different plan and the information below may not apply to your individual plan.
Please call your insurer or employer's benefits department for the most current and accurate information regarding coverage and requirements of your plan.
If your insurance or employer changes at any time, please let us know as soon as possible as this can impact your coverage.
We recommend that you call the customer service number on the back of your insurance card and ask if bariatric surgery is a covered benefit, and if there are any specific requirements for the surgery to be covered.
It is important to understand your financial responsibilities before you begin this journey, so ask lots of questions!

Have significant health issues that would improve with weight loss?
Have a BMI of 35 or more with weight-related comorbidities?
Have a BMI of 40 or more without weight-related comorbidities?

If you are an adult 18 years or older and answered YES to any of the above questions AND are a non-smoker (you must be tobacco- and nicotine-free for at least three months prior to pre-surgery education) then you are likely a good fit for bariatric weight loss surgery.
