Frequently asked questions (FAQs)

Why is bariatric surgery done?
  • To reduce your risk of potentially life-threatening weight-related health problems.
  • To lose excess weight.
Are there general requirements to qualify for bariatric surgery?
  • Yes. Most insurance companies only cover surgery when a patient has a BMI (body mass index) of 40.
  • Patients with BMI of 35-39.9 and suffer from comorbid conditions such as heart disease, type 2 diabetes or other health problems may qualify (you can calculate your BMI via the tool under “How do I figure out my BMI?” below).
  • Patients need to have quit smoking at least 8 weeks prior to surgery, and also cannot be using drugs or alcohol.
  • All patients need to complete a psychological evaluation and nutrition class prior to surgery.
  • Patients must meet other specified requirements as outlined by their insurance plan for surgery to be covered.

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.
