Weight-loss procedure options

Based on your weight-loss needs and goals, you have options at Gundersen. Gastric bypass and gastric sleeve are today’s safest and most effective surgeries for weight loss, and we also offer non-surgical procedures. 

Minimally invasive gastric bypass surgery (laparoscopic Roux en Y)

During a Roux en Y gastric bypass, a surgeon creates an egg-sized pouch from the upper part of your stomach. The pouch is then connected to your small intestine, bypassing your stomach. Doing so can improve reflux, diabetes and other health conditions.

Gastric sleeve surgery (vertical sleeve gastrectomy or VSG)

During gastric sleeve surgery, a surgeon makes your stomach smaller to limit how much you can eat before you feel full. Your stomach is about the size and shape of a banana after the procedure. Unlike with gastric bypass surgery, the rest of your digestive tract remains unchanged.

Orbera® intragastric balloon (non-surgical)

With Orbera®, a silicone balloon is inserted with a scope into your stomach. The balloon is then filled with saline until it’s about the size of a grapefruit. After six months, the balloon is removed. The process reinforces portion control.

Adjustable gastric banding maintenance, removal and conversion

We do not place gastric bands or perform lap band surgery at Gundersen, but we'll help you manage your adjustable gastric band if you have one. This includes converting it to a different surgical option if necessary.

What to expect

Getting started

Preparing for bariatric surgery often takes six or more months. We’ll be with you every step of the way. Here's what to expect:

Education: Our free online Weight-Loss Surgery Seminar is the first step toward surgery. You'll also attend nutrition classes and other educational opportunities. 

Evaluations: Medical, psychological and other evaluations will be done to make sure surgery is the best option for you. If it's not, we'll discuss other treatments.

Payment options & insurance: If your insurance covers weight-loss surgery, you’ll need to meet your carrier’s requirements. We’ll help you navigate this process and submit to your insurer. If you don’t have insurance or you choose to pay out of pocket, we offer competitive prices. Please contact us for more information.

Scheduling surgery: After you meet all program requirements and get the green light to proceed from your insurance company, your surgery and all pre-operative appointments will be scheduled.

Long-term follow-up: Choosing weight-loss surgery means choosing lifelong follow-up care. This means regular visits in the first year and annual visits for life with our weight-loss doctors. We also offer a monthly bariatric support group to help you after surgery.
