What is Bariatric Surgery?

Also known as weight-loss surgery, bariatric surgery limits the amount of food you’re able to comfortably eat and/or decreases your absorption of food and calories. Bariatric surgery is considered the most successful weight-loss treatment option because it modifies gut hormones that signal hunger, resetting the body’s metabolism.

What Are the Benefits?

Weight loss surgery does not just treat the disease of obesity, it positively impacts a multitude of weight-related conditions such as asthma, depression, obstructive sleep apnea and cardiovascular disease, among others.

Am I a Candidate?

Most candidates for bariatric surgery have:

  • At least 100 pounds to lose or a body mass index (BMI) greater than 40
  • A BMI of at least 35 and a weight-related health complication, such as Type 2 diabetes, sleep apnea, hypertension, joint disorders and gastrointestinal conditions
  • Many people who qualify for bariatric surgery don’t realize their health insurance may cover the costs. Our team can help you determine your eligibility for weight loss surgery and launch you on a path to a healthier you.

How Safe is Bariatric Surgery?

Bariatric surgery is safer than getting your gallbladder removed. With minimally invasive surgical techniques, patients experience less pain, fewer complications, a shorter hospital stay and faster recovery.

Types of Surgery We Offer

We offer these weight-loss surgery options:


    The Sleeve Gastrectomy is one of the most commonly performed surgeries today. This minimally invasive surgery involves the removal of up to 80% of the stomach, restricting the amount of food you can eat at one time.


    The Roux-En-Y, more commonly known as Gastric Bypass, has been in practice for more than 30 years. It involves separating the upper portion of the stomach from the lower and rerouting the digestive system to restrict the amount of food you can eat at one time and alter the absorption of nutrients and calories.


    Gastric revision surgery is a procedure performed to correct issues or improve outcomes for patients who underwent prior weight loss surgery and have unexpected complications, side effects, or did not achieve their anticipated weight loss goals.

Did You Know?

Obesity is a serious health condition. Making the decision to undergo weight-loss surgery impacts not only your weight but a myriad of related conditions including type 2 diabetes, hypertension and obstructive sleep apnea, among others. Undergoing surgical treatment can dramatically improve your health, quality of life and result in a longer lifespan.
