Bariatric surgery

Why it’s done

  • To reduce your risk of potentially life-threatening weight-related health problems.
  • To lose excess weight.

Who it’s for

In general, weight loss surgery could be a treatment option for you if:

  • Your body mass index (BMI) is 40 or higher.
  • Your BMI is 35-39.9 and you have a serious weight-related health problem.

The type of bariatric surgery that works best for you will depend on several factors. You and your physician will discuss the best option for your situation.

Laparoscopic sleeve gastrectomy

Laparoscopic sleeve gastrectomy, or LSG, is performed by making about five small cuts in your belly. Your surgeon will perform the surgery using a thin, long, telescope with a tiny camera at the end. Instruments pushed through the incisions will be used to remove about 80% of your stomach.

Gastric bypass

Gastric bypass surgery reduces the size of your upper stomach to a small pouch about the size of an egg. The surgeon does this by stapling off the upper section of the stomach. This reduces the amount of food you can eat. The surgeon then attaches this pouch directly to part of the small intestine called the Roux limb. This forms a “Y” shape. The food you eat then bypasses the rest of the stomach and the upper part of your small intestine.

This procedure reduces the amount of fat and calories you absorb from the foods you eat. It also reduces the amount of vitamins and minerals you absorb from food.

The cost of bariatric surgery, and whether it is covered by insurance, varies.

Our bariatric patient navigator will contact each patient’s insurance company to find out if the cost of bariatric surgery is covered under the patient’s benefits and if there are any pre-surgery requirements.

Insurance Plans Accepted

We accept most insurance plans, including:

Blue Cross and Blue Shield

Within each of those companies, however, there are many policies that don’t cover the cost of bariatric surgery. Our bariatric patient navigator will help determine if your particular insurance plan offers coverage.

If your insurance will not cover bariatric surgery, we do have a self-pay option.

*UCHealth Bariatric Center of the Rockies accepts and provides care for those with Medicare and Medicaid coverage — one of the few facilities in Colorado to do so.

After bariatric surgery

Patient testimonials

Cathy DoughertyKeith GastonConnie GieseJohn MillerMichaela MillerJonathan Rhoades

Cathy Dougherty lost 124 pounds.

“I have more confidence and I’m much happier,” she said. “I don’t get grumpy like I used to because I’m not as tired as I used to be. I’m living the life.”

UCHealth bariatric patient Cathy Dougherty

Keith Gaston lost 180 pounds.

After seeing a friend’s success with weight-loss surgery, Keith decided that he wasn’t ready to give up—he wanted to spend more time with his kids, and if he wanted to live, he had to make a change. In this case, that change changed everything.

Connie Giese lost 110 pounds.

“It’s like the entire hospital has gone on this journey with me,” she said. “They’ve been so supportive. At times even when I couldn’t see the change in myself, they always could and would say things like, ‘You look so great!’ It was so nice to have the boost from others.”

John Miller lost 202 pounds.

At 6′ 4″ and nearly 500 pounds, John had several of the issues caused by morbid obesity: knee and back pain, trouble sleeping, shortness of breath, trouble getting in and out of his truck. “It’s such a dramatic difference. I wish I would have done it 10 years ago.”

Michaela Miller lost over 160 pounds.

Since her surgery Michaela doesn’t even recognize the person she used to be. In 2017 she completed the Warrior Dash, something she would have never attempted pre-weight loss. Her surgery changed her appearance, her energy, her confidence, and her life. “I feel like I am finally who I was meant to be all along,” she said.

Jonathan Rhoades lost
208 pounds.

Before weight-loss surgery, Jonathan never would have pictured himself climbing over a barrier, pulling himself up on stage and dancing with one of his favorite Celtic punk bands, the Dropkick Murphys. “I didn’t even realize before I lost the weight just how much of a physical struggle it was or how much I was limiting myself,” he said.
