Weight-loss surgery in Oklahoma

Bariatric care teams at Ascension hospitals in Oklahoma provide bariatric surgery and nutrition counseling for weight loss.

Bariatric surgery and weight management

Bariatric surgery helps support weight loss by reducing the size of your stomach and, in some procedures, changing how your body absorbs nutrients. These changes help you feel full sooner, reduce appetite, and support long-term weight loss.

The bariatric care teams at Ascension St. John in Tulsa and Bartlesville, Oklahoma provide comprehensive surgical and medically supervised weight-loss care.

Weight-loss surgery is a deeply personal and potentially life-changing decision. Our doctors and nurses take the time to listen, understand your goals, and partner with you to create a plan that fits your health needs and lifestyle.

Bariatric surgeries/procedures 

Surgical weight-loss procedures

Our bariatric surgeons specialize in minimally invasive procedures designed to support safe and effective weight loss, including:

  • Roux-en-Y gastric bypass
  • Sleeve gastrectomy
  • Single Anastomosis Duodeno-Ileostomy with Sleeve Gastrectomy (SADI-S)
  • Revision of previous weight-loss surgeries

Minimally invasive techniques may help reduce pain, shorten recovery time, and support a faster return to daily activities.

Is bariatric surgery right for me?

You may be a candidate if you can answer “yes” to one or more of the following:

  • BMI >35 with another health condition OR BMI >40 with or without additional health condition
  • Does my current weight contribute to chronic health conditions such as diabetes, high blood pressure, sleep apnea, or joint pain?
  • Am I willing to commit to weight-loss efforts required by my insurance plan?
  • Am I ready to make long-term changes to my diet, physical activity, and overall health?

Endoscopic bariatric procedures

Endoscopic weight-loss procedures are non-surgical options performed through the mouth without incisions. These procedures may be appropriate for patients who do not meet criteria for traditional bariatric surgery or who prefer a less invasive approach.

These procedures may be appropriate for patients with:

  • A BMI of 30–50 
  • Weight-related health conditions
  • A desire for a non-surgical or revision option
  • Previous bariatric surgery with weight regain (procedure-dependent)

Additional considerations:

  • Performed without external incisions
  • Typically shorter recovery time
  • Requires commitment to lifestyle and nutrition changes
  • Must be paired with ongoing medical and nutritional support

Your provider will help determine whether an endoscopic procedure is appropriate based on your medical history and goals.
